The answer will be letter B because after work people need some energy
Answer:
y = 12,000x + 40,000
Explanation:
A linear relationship that would model the mileage of the car in this example is:

where
y is the number of miles
x is the number of years
m is the number of miles driven per year
q is the number of miles already in the car at x=0
In this problem, we have
m = 12,000 (number of miles driven per year)
q = 40,000 (number of miles already in the car at x=0)
So substituting into the equation we get

Chemical energy comes from the food that we eat
Answer:
<h2>9.39 m/s</h2>
Explanation:
The velocity of the bowling ball can be found by using the formula

p is the momentum
m is the mass
From the question we have

We have the final answer as
<h3>9.39 m/s</h3>
Hope this helps you
Answer:
The recoil speed is 
Solution:
Wavelength of a blue-green photon, 
Now, the energy associated with the blue-green photon:

where
h = Planck's constant
C = speed of light ion vacuum


Also, we know that the recoil speed can be calculated by the KInetic energy which is equal to the Energy of the blue-green photon:

where
= velocity of Hydrogen atom
= mass of H-atom
Now,
