Answer:
The energy stored in the bungee cord is 43,750 J.
Explanation:
Given;
extension of the bungee cord, x = 25 m
spring constant of the bungee cord, k = 140 N/m
The elastic potential energy stored in the bungee cord is calculated as;
U = ¹/₂kx²
U = ¹/₂(140)(25)²
U = 43,750 J
Therefore, the energy stored in the bungee cord is 43,750 J.
Explanation:
The given data is as follows.
Speed of the bullet (v) = 500 m/s
Distance during one RC time constant (d) = 1 mm =
Capacitance (C) = 600 =
Hence, formula for speed of the bullet is as follows.
v =
or, t =
Time constant for RC circuit is as follows.
t = RC
R =
=
=
=
Thus, we can conclude that resistance in the flash tube is .
Answer: The third law states that for every action (force) in nature there is an equal and opposite reaction.
Explanation:
if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A. Notice that the forces are exerted on different objects.
