The equation for power is P=w/t, where w=work done in joules and t=time in seconds.
in this case:
p=w/t
p=3500/25
p=140
so, the boat was using 140 watts of power.
momentum = mass * velocity
62.5 = mass * 3.6
mass = 62.5/3.6
mass = 17.36 kg
insulator.
it has no electrons free within it to move and to make an electric current
The kinetic energy decreases
Answer:
Option (C)
Explanation:
Recreational drugs are usually referred to those drugs or medicines that are legally or illegally used without any prescription given by the doctors. These drugs include marijuana, cocaine, alcohol, nicotine, heroin, and many others. These drugs provide relaxation for a shorter period of time, but using of these substances, it makes an individual addicted to drugs.
