Two toy cars (16kg and 2kg) are released simultaneously on aninclined plane that makes an angle of 30` with the horizontal. which statement best describes their acceleration after beingreleased? and why?
a) the 16-kg car accelerates 8 times faster than the 2-kgcar.
b) the 2-kg car accelerates 8 times faster than the 16-kgcar.
c) both cars accelerate at a rate of (0.87)g.
d) both cars accelerate at a rate of (0.50)g.

D

Explanation:

On an inclination of 30°, the acceleration down the inclination will be gsinФ. So the acceleration will be  ⇒

                        g Sin30° = (0.50) g

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

false
