Flapping Flight Is Very Energy Intensive. A Wind Tunnel Test On An 89 G Starling Showed That The Bird (2024)

Physics High School

Answers

Answer 1

There would be 546.254 g to consume to fuel this flight. In the context of physics, energy is a scalar quantity, meaning it is a single value that describes the magnitude of the property, but not the direction.

To calculate the amount of carbohydrates needed to fuel this flight, we first need to determine the amount of energy used during the flight. Energy is a property of matter and radiation that allows it to do work.

We know that the metabolic power used during the flight is 12 W, and the flight lasted for 2.0 km / 11 m/s = 182.18 s.

To find the energy used in Joules, we can use the formula:

Energy (J) = Power (W) x Time (s)

Energy = 12 W x 182.18 s

Energy = 2185.016 J

We know that the body converts carbohydrates into energy, and that 1 gram of carbohydrates is equivalent to about 4 calories.

Therefore, to find the number of grams of carbohydrates needed to fuel the flight, we can divide the energy used in Joules by the number of calories per gram of carbohydrates:

grams of carbohydrates = Energy (J) / (Calories/gram)

grams of carbohydrates = 2185.016 J / 4 J/cal

grams of carbohydrates = 546.254 g

a particle whose mass is 30.0 grams and whose charge is 5 nc is released from rest when it is 20 mm from a second particle of charge 10 nc. find the magnitude of the first particles initial acceleration in m/s^2

Answers

The magnitude of the first particle's initial acceleration in [tex]2.25 * 10^6 m/s^2[/tex]

The equation for the force between two charged particles is:

F = (k * q1 * q2) / d^2

where k is the Coulomb constant (8.99 x 10^9 Nm^2/C^2), q1 and q2 are the magnitudes of the charges, and d is the distance between them.

Since the first particle is released from rest, its initial acceleration is equal to the net force acting on it, which is the force between the two charged particles.

So,

a = F / m

where m is the mass of the first particle. Substituting the values and converting units, we get:

[tex]a = (k * 5 * 10^-^9 * 10 * 10^-^9 ) / (0.02 )^2\\\\a = (8.99 x 10^9 /C^2 * 5 * 10^-^9 * 10 x 10^-^9 ) / (0.02 )^2\\\\a = 2.25 x 10^6 m/s^2[/tex]

What is Coulomb's Law?

According to Coulomb's law, the force of attraction or repulsion between two charged bodies is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

what is the maximum speed for a car rounding a 125 m curve on a highway under very icy (no friction) conditions if the banking angle is 20.0o.

Answers

the maximum speed for a car rounding a 125 m curve on a highway under very icy (no friction) conditions if the banking angle is 20.0 is 70.3 km/h.

If a car is driving on a highway with a banking angle of 20.0o and icy (no friction) conditions, the maximum speed it can reach while rounding a 125 m curve is determined by the following calculations:

The maximum centripetal acceleration (a) is equal to the gravitational acceleration (g) multiplied by the sine of the banking angle (θ). In this case, a = g * sin(20.0o) = 9.8 m/s2 * 0.3420201433 = 3.36 m/s2.

The maximum speed (v) is then equal to the square root of the maximum centripetal acceleration (a) multiplied by the radius of the curve (r). In this case, v = √(3.36 m/s2 * 125 m) = 19.6 m/s = 70.3 km/h.

Therefore, the maximum speed a car can reach while rounding a 125 m curve on a highway under very icy (no friction) conditions if the banking angle is 20.0o is 70.3 km/h.

a fisherman throws the iron anchor from his floating boat into the lake. does the level of the lake rise, fall, or stay unchanged?

Answers

When the fisherman throws the iron anchor from his floating boat into the lake the level of the pond falls.

With the introduction of the "CQR," created by Scottish inventor Geoffrey Ingram Taylor in the early 1930s, modern boat anchor development has progressed rather independently from that of the first half of the 20th century. Since this design was asymmetrical, bow rollers had to be used to efficiently stow it. This works well for small yachts and boats, but it doesn't scale well for huge cargo. Lewmar is now the company producing the CQR.

In the 1940s, American Richard Danforth created and refined the "Danforth" pattern, a nod to symmetry but with very broad flat plate flukes. This anchor performs poorly in other areas but has very good holding power for its weight (high efficiency), making it ineffective.

While the anchor is in the boat, its weight displaces a volume of water V1 equal in weight to the anchor (by Archimedes' principle). After being thrown overboard, the sunken anchor displaces a lesser volume of water V2, equal in volume to the anchor.

V2 is less than V1 because the anchor is denser than water (otherwise it would not sink!) So, with less water displaced, the level of the lake falls.

Therefore, When the fisherman throws the iron anchor from his floating boat into the lake the level of the pond falls.

What is the kinetic energy of a 5.0 kg?

Answers

The kinetic energy of a 5.0 kg is 2.5v² Joule. We assume that the object is moving.

What is kinetic energy?

Kinetic energy is the energy of an object due to its motion. So, if an object is moving, it has kinetic energy.

The energy is equal to half mass of an object multiplied by the square of its velocity. The statement can be expressed as

KE = ½ mv²

Where

KE = kinetic energy (J)m = mass of object (kg)v = velocity of object (m/s)

Find the kinetic energy of an object with a mass of 5.0 kg!

We have

m = 5.0 kg

When the object is moving, it has

v = velocity of the object

It would have the kinetic energy of

KE = ½ mv²

KE = ½ (5.0)v²

KE = 2.5v² Joule

Hence, a 5.0 kg of object will have the kinetic energy of 2.5v² Joule.

a) What current would be required to provide a lifting force of 300 N?

b) If the current is 2.5 A, how many turns would be required to provide a lifting force of
600 N?

Answers

a) The lifting power of an electromagnet is proportional to the current and the number of revolutions.

To calculate the current necessary to create a lifting force of 300 N, use the proportion:

(current) / (2000 turns) = (300 N) / (100 N)

When you solve for current, you get:

current = (2000 turns) * (300 N) / (100 N) = 6 A

b) The percentage may be used to calculate the number of spins necessary to create a lifting force of 600 N:

(2000 turns) * (2.5 A) = (number of turns) * (2.5 A)

If you solve for the number of turns, you get:

2000 turns = (2000 turns) * (2.5 A) / (2.5 A).

Over the course of Earth's history, the atmosphere has undergone a number of dramatic changes. Early in its existence, hydrogen and helium made up the majority of the atmosphere of Earth. However, throughout time, these gases slowly dissipated and were replaced by heavier molecules like nitrogen, oxygen, and carbon dioxide. Either through volcanic eruptions or the weathering of rocks, these chemicals entered the atmosphere.

Water vapour started to condense as the earth cooled, creating clouds and eventually rain. This precipitation interacted with atmospheric carbon dioxide to create carbonic acid, which eventually dissolved rock minerals and created an ocean. A carbon cycle that allowed for the exchange of carbon dioxide between the atmosphere and the ocean was created over time as a result of interactions between the ocean and atmosphere.

what is the relationship between the index of refraction of a material and the speed of light in that material

Answers

A material's index of refraction is inversely proportional to its light speed. The speed of light in a vacuum is equal to the index of refraction (n).

Relationship between index of refraction and speed of light :

Quantitative Law of Refraction:

Snell's Law n₁ Sinθ₁ = n₂ sinθ₂.

n = 1, for a vacuum.

What does it mean to have a higher index of refraction?

The slower the light travels, the higher the refractive index, which in turn causes the material to change in the opposite direction of the light. This means that lenses made of materials with a higher refractive index can bend light more and have a lower profile.

Why does light travel so quickly?

There is nothing that can travel faster than 300,000 km/s (186,600 miles/s). That speed can only be reached by massless particles, like photons, which make up light. Because it would require an infinite amount of energy to accelerate any material object to the speed of light, it is impossible to do so.

a boy shoots a section-cup dart at a refrigerator where it sticks. if the suction cup has a diameter of 0.5 inches when stuck, what force in lbf is required to pull it straight off?

Answers

The force required to pull a suction cup off of a surface is determined by the adhesive strength of the suction cup and the surface it is attached to, as well as the size of the suction cup.

The larger the suction cup, the more force is required to remove it. In this case, with a suction cup diameter of 0.5 inches, the force required to pull it straight off of a refrigerator would likely be relatively small.

It's important to note that the suction cup is designed to stick to a smooth surface and the force required to pull the suction cup off is directly proportional to the area of the suction cup in contact with the surface.

The force required to pull the suction cup off can be calculated using the following formula: Force = (Adhesive strength of suction cup × Area of suction cup) / (Coefficient of friction between suction cup and surface).

In conclusion, the force required to pull the suction cup dart off the refrigerator depends on the adhesive strength of the suction cup, the size of the suction cup, and the coefficient of friction between the suction cup and the refrigerator surface.

Without the exact values of these parameters, it's difficult to give an exact value of the force required. But it's likely to be relatively small as the suction cup is small and it's designed to stick to a smooth surface.

Also, the force required will depend on how the boy has shot the dart and how it's adhered to the surface. In any case, the force required is not likely to be significant enough to cause damage to the refrigerator.

I have two charges of +4 x 10-5 C. If they are 0. 5 m apart, what is the electric force between them?

Answers

Coulomb's law, states that the force between two charges is proportional to the product of the charges and inversely proportional to the square of the distance between them, can be used to compute the electric force.

The equation is: F = k * (q1 * q2) / r^2

where F is the electric force, k is Coulomb's constant (9 x 10^9 N * m^2 / C^2), q1 and q2 are the charges, and r is the distance between them. So, in this case, the electric force between the two charges of +4 x 10^-5 C would be:

F = (9 x 10^9 N * m^2 / C^2) * ((+4 x 10^-5 C) * (+4 x 10^-5 C)) / (0.5 m)^2

F = (9 x 10^9 N * m^2 / C^2) * (16 x 10^-10 C^2) / (0.5 m)^2

F = (9 x 10^9 N * m^2 / C^2) * (16 x 10^-10 C^2) / (0.25 m^2)

F = 36 x 10^9 N. So the force between the two charges is 36 x 10^9 N.

A box has a volume of 0.38m² and is 70% filled with iron filling at 25°C. Calculate Lotal mass of the iron filling quantity of heat absorbed (Density of iron = 8x10² kg/m³ Specific heat capacity of iron = 460 Jkg-¼k-1 temperative of iron=1500°c​

Answers

The iron filling's mass is equal to 0.38 x 0.7 x 8 x 102 kg.

5,023,360 J of heat are absorbed.

Explain about the law of energy conservation.

This question uses the rule of conservation of energy, which states that energy cannot be created or destroyed but can only be transformed from one form to another.

In this instance, the energy is changed from kinetic energy (force) to thermal energy (heat) (motion of the iron particles).

Determine the iron filling's mass in step one.

Mass of iron filling is calculated as follows: Volume of box x Fill Ratio x Iron Density

= 0.38m² x 0.7 x 8 x 10²

= 22.08 kg

Calculate how much heat is absorbed in step two.

Amount of heat absorbed = Mass of the iron filler x Iron's specific heat capacity x (Temperature of Iron - Temperature of Box)

= 1.500° to 25°C x 22.08 kg x 460 Jkg-14k-1

= 5,023,360 J

Suppose a scrawny 20. Kg Wyle was shot straight up with an initial velocity of +50 m/s.
a. Assuming that all his initial Ek was transformed into Eg, what is the maximum height he could reach?

b. Suppose that 20% of his initial Ek were lost due to friction with the air (air resistance).
What is the maximum height he could reach?

Answers

(a) If all of his initial velocity were converted into an equation, his highest point would be at a height of y = 127.6 m.

The tallest he could get was (b) h = 102.08m.

What is the straightforward meaning of velocity?

The dislocation that an element or particle experiences with the passage of time is expressed vectorially as velocity. The centimeter per second (m/s) is the accepted unit of velocity profiles (also known as speed).

What is the SI unit for velocity?

The velocity is the rate at which a given displacement changes. By figuring out the displaced to total time ratio, it may be estimated. The same as for speed, "m/s" is the SI unit for velocity.

V = 50 m/s

a = - 9.8m/s²

y = ?

0 = 50² + (-9.8)y

y = 127.6 m

= 127.6 * .2

= 25.52 m

= 127.6 - 25.52m

h = 102.08m
