Its B: reduce the amount of energy needed to do the work by putting the work onto something else
Energy is transfered when its moved from one object to another. The rate of energy transfered is called power. Work is the transfer of energy from one object to another.
Answer:
48m
Explanation:
- Initial velocity = 4m/s
- Acceleration = 4m/s²
- Time = 4s
- Displacement = ?
From Second equation of motion ,
s = ut + 1/2at²
s = 4*4 + 1/2*4*(4)² m
s = (16 + 2 * 16) m
s = ( 16 + 32 )m
s = 48 m
It's difficult to measure that because it's hard to make sure it is only a uniform layer of gas in whatever you're measuring it in
