Answer:
<h2>103 Joules</h2>
Explanation:
In this problem we are required to find the potential energy possessed by the television
Given data
mass of television m = 15 kg
height added above the ground, h= 1-0.3 = 0.7 m
acceleration due to gravity g = 9.81 m/s^2
apply the formula for potential energy we have
P.E= m*g*h
P.E = 15*9.81*0.7 = 103 Joules
Answer:
A
Explanation:
It is less than the acceleration of the backpack because abs has a greater mass.
Its A: the use of hydropower often changes the natural flow of water through an ecosystem
