Suppose a fly and an eagle have the same kinetic energy. How could this be true?

Physics

Readme [11.4K]4 years ago
6 0

Answer:

The fly must be moving at a greater speed than the eagle

Explanation:

The kinetic energy of an object is given by

K=\frac{1}{2}mv^2

where

m is the mass of the object

v is its speed

In this problem, we have a fly and an eagle, and they both have same kinetic energy. We also know that the eagle has a much larger mass m than the fly: therefore, since the kinetic energy depends only on m and v, in order for the two animals to have same K, it means that the fly must have a much larger speed v than the eagle.

A mixture of N2, H2 and He have mole fractions of 0.25, 0.65, and 0.10, respectively. What is the partial pressure of N2 if the
matrenka [14]

Answer: The partial pressure of N_2 if the total pressure of the mixture is 3.9 atm is 0.975 atm

Explanation:

According to Raoult's law, the vapor pressure of a component at a given temperature is equal to the mole fraction of that component multiplied by the vapor pressure of that component in the pure state.

p_A=x_A\times P_T

where, x = mole fraction of nitrogen in solution = 0.25

p_A = partial pressure  of nitrogen = ?

P_T = Total pressure = 3.9 atm

Putting in the values :

p_A=0.25\times 3.9=0.975atm

The partial pressure of N_2 is 0.975 atm

As an object increases its speed, its kinetic energy
Juliette [100K]

Answer:

Increase

Explanation:

Kinetic energy is the energy of motion--so the overall energy of that object would increase. Kinetic energy of an object is directly proportional to the square of its speed.

How do solar panels create electricity
xenn [34]

Answer:

They create electricity from the sun's  rays

Explanation:

By the use of "solar cells" or "solar panel", you can trap solar energy in silicon/germanium rods, then you can convert in into electricity too. Solar powered panels convert the sun's rays into electricity by exciting electrons in silicon cells using the photons of light from the sun. This electricity can then be used to supply renewable energy to your home or business.
