Answer:
E = 73.5 J
Explanation:
Given that,
Mass of a marble, m = 5 kg
It is placed at the edge of a 1.5 m table
We need of find the gravitational potential energy of the marble. It is given by the formula as follows :
E = mgh
E = 5 kg × 9.8 m/s² × 1.5 m
E = 73.5 J
So, the potential energy of the marble is 73.5 J.
Pearl Ash is an example of an Impure Potassium Carbonate
By idea gas equation we can say
here P = pressure
V = volume
n = number of moles
R = Avagadro gas constant
T = temperature
So from above expression you can see that for constant number of moleswe can say
So finally the volume will be 43.9 L
Answer:
Under normal conditions – closed circuit – these contacts are touching each other, allowing the flow of electric current. These moving contacts are held together thanks to mechanical pressure exerted by another mechanism – a spring or compressed air
