Answer:
P = 96 J
Explanation:
Given that,
Weight of the book, W = mg = 8 N
It is placed at a height of 12 m
We need to find the potential energy of the book. The potential energy of an object is given by the formula as follows :
E = mgh
mg = Weight
So, the potential energy of the book is 96 J.

I was also going to ask same question edited:ok i found its true
Answer:
Explanation:
To plot the given forces of 0.8 N and 0.9 N. It is convenient to take
0.1 N as 1 unit in Graph
For example, 1 unit in the graph is 1 cm
then take 0.1 N equivalent to 1 cm
Answer:
1. Static electricity is caused by the build up of electrical charges on the surface of objects, while current electricity is a phenomenon from the flow of electrons along a conductor. 2. When objects are rubbed, a loss and/or gain of electrons occurs, which results in the phenomenon of static electricity.
Explanation:
Answer:
The Kelvin temperature scale is used by scientists because they wanted a temperature scale where zero reflects the complete absence of thermal energy. ... Many quantum mechanical properties are washed out by the thermal agitation that occurs in materials.
