43.62m
Explanation:
Given parameters:
Energy = 8550J
Mass of bell = 20kg
Unknown:
Height of the bell = ?
Solution:
As this state, the bell possesses potential energy. Potential energy is the energy at rest in a body. It is due to the position of the body.
Potential energy = m g h
m is the mass of the body
g is the acceleration due to gravity of the body
h is the height of the body
The unknown is h and we should solve for it.
g = 9.8m/s²
Input the variables;
8550 = 20 x 9.8 x h
h = 43.62m

The answer is Abecaue it is the most specific on how
Answer:
Option B. PV = nRT.
Explanation:
From the above,
C = PV / T. (1)
But, C is directly proportional to n, where R is the gas constant i.e
C & n
C = nR
Substituting the value of C into equation (1), we have:
C = PV / T
nR = PV / T
Cross multiply to express in linear form
nRT = PV
Therefore,
PV = nRT
