Two cars collide at an intersection. one car has a mass of 1300 kg and is
moving 12 m/s to the north, while the other has a mass of 1400 kg and is
moving 11 m/s to the south. what is their combined momentum?
o
a. 200 kg•m/s south
b. 31,000 kg*m/s south
o
c. 31,000 kg•m/s north
o
d. 200 kg-m/s north

answer: a. same unit

explanation:

answer; how far out of place which the object finished relative to the starting location;

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
