1. Two ladies of different masses are standing on ice skates in the middle of a skating rink. The push each other as shown above. The smaller lady
acquires a velocity of 4.2 m/s. Which of the following must be true of the
larger lady? *

b.transmitters send radio waves, and receivers capture radio waves.

power out to power in less than 100%

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

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
