</span>When gasoline is burned in a car engine, chemical energy is converted into mechanical energy.
I think it is c I'm only in 7th grade but I'm pretty sure that the answer is c
Average velocity = (800+1600)/(4+10)
= 171.42m/s
Answer:
C. 0.2 Hertz
Explanation:
The frequency of a spring is equal to the reciprocal of the period:

where
f is the frequency
T is the period
For the spring in this problem,
T = 5 s
therefore, the frequency is

The period of the wave would be halved
