B Yea that should be the right answer
The change in the internal energy of the system is 110 kJ.
<h3>What is internal energy?</h3>
Internal energy is defined as the energy associated with the random, disorder motions of molecules.
calculate the change in internal energy, we apply the formula below.
Formula:
- ΔU = Q-W.................... Equation 1
Where:
- ΔU = Change in internal energy
- Q = Heat absorbed from the surroundings
- W = work done by the system
From the question,
Given:
Substitute these values into equation 1
Hence, The change in the internal energy of the system is 110 kJ.

Since kinetic energy is a form of energy using the equation KE=¹/₂mv², the units of measurement is in Joules (J). Therefore, the tennis ball had more kinetic energy than the baseball since velocity is a larger factor than the mass is when determining kinetic energy.
Answer:
96 mph
Explanation:
There are a couple of ways of doing this, but I will just use a proportion.
first off 1 hour = 60 minutes.
So 144/90 = x/60 will give me the answer per 60 minutes of miles per hour.
cross multiply to get 90x = 8640
divide by 90 to get 96 miles per 60 minutes or 96 mph.
Hope this helped.
