5. A 60-kg man is in an elevator that is accelerating down- ward at the rate of 1.4 m/s2.
a. What is the true weight of the man in newtons?
b. What is the net force acting on the man required to pro-
duce the acceleration?
C. What is the force exerted on the mans feet by the floor of the elevator
D. What is the apparent weight of the man in Newton’s
E. How would your answers to part b through d change if the elevator were accelerating upward with an acceleration of 1.4 m/s2.

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.

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
