Answer:
last is the answer.
increase the voltage in order to send energy faster.
Mass=600kg
Velocity =15m/s
Momentum(p)=?
Now,
P=mass x velocity
=600x15
=9000kgm/s
Answer:
C would probably be the best answer.
Explanation:
Switches control the flow of an electrical current in a circuit. Switches open or close the circuit. If you open a circuit, you turn it off, and if you close it, you turn it on.
Accelration=changespeed/changetime
changetime=8
changespeed=45-5=40
40/8=5
5m/s^2 is acceleration
