Mr. Graba (mass 58 kg) is standing on a swim mat that is initially at rest. Having become warm Mr. Graba jumps off the mat with a velocity of 10 m/s East. With what velocity (include direction) does the 3 kg platform move after? The swim mat is not anchored

the temperature in kelvin of 2.0 dm3 of an ideal gas is doubled and its pressure is increased by a factor of four. what is the final volume of the gas

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
