A baseball would hit the bat harder. This is because the baseball is a lot heavier and more dense than the plastic ball. The keyword that you're looking for is density. The baseball is dense.
Answer:
simple, Volt =change in potential energy/Charge
the unit of energy is newton meter (Force*distance)
the unit of charge is coloumb
So, Volt/meter=newton* meter/coloumb*meter
=newton/coloumb (hence proved)
This unit is the potential drop per unit of length in a conductive wire with uniform resistance
The answer is D. The input force is equal to the output force.
I just did test and got it right
Answer:
the car you are in the cars have the same time frame and one covers more ground so on a possition time graph the slope will be greater
