Answer:
Explanation:
Let initial mass of the moving car is m it is moving with the speed of v m/s.
Thus, Kinetic energy of the car is given by,
Initial Kinetic energy =
Now the velocity of moving car is changed to 3v where as its mass remains the same.
Thus, Kinetic energy of the car is given by,
Final Kinetic energy =
Final Kinetic energy =
The change in kinetic energy is given by,
Change in kinetic energy
= Final kinetic energy - initial kinetic energy
= -
=
Thus, when the speed of a moving car is tripled, kinetic energy is
Answer:
According to Newtons 2nd law of motion ;
The acceleration an object experiences is as a result of the net force which is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
Explanation:
This law is simply saying ;
Force = Mass ×Acceleration

The famous equation . . . E = m c² . . . doesn't say anything about where the mass comes from.
The total conversion of 1 kg of ANY mass into energy yields
(1kg) · (c²) Joules of energy.
E = (1 kg) · (c²) = (1 kg) · (299,792,458 m/s)²
<em>E = 8.9876 x 10¹⁶ Joules</em>
To put this in easily understood terms, it's the amount of energy required to keep a 100-watt light bulb shining for 10,402,259,010 days.
(That's about 28.5 million years, at the current length of days and years.)
Answer:
B.
Explanation:
The water collects in the ocean; it is then evaporated by the sun. After evaporation the water turns into water vapor, it then condenses to form clouds.
Power = energy / time
Time should be in seconds
5 hours = 5 × 60 minutes = 5 × 60 ×60 seconds = 18000 s
Power = 6000/18000 = 0.333 W
Hope it helped!
