Work = force x distance. In units, Joules = Newtons x meters.
So: Work = 50 Newtons x 3 meters
Work = 150 joules. Answer D is correct
FYI - to ace physics, you should learn to identify these values using their fundamental units:
Force = Newtons = Kg·m/s²
Work = joules = kg·m²/s²
Power = watts = kg·m²/s³
In high school physics, If you learn to arrange equations so the units work out properly for the answer, you'll get most problems correct.
b) accelerate to the left as much more pressure is pulling it in that direction and on the right however , there is less force .
Neutron is commonly used to initiate a fission chain reaction.
<span>A= a=99/85.3
B= a=-54/85.3
C=The acceleration is smaller.
