Answer:
Change in potential energy is 700.7 J.
Explanation:
Given:
Mass of the object is, kg
Height to which the object is raised above his head, m
Acceleration due to gravity is, m/s²
We know that for a mass raised to a height
, the change in potential energy is given as:
, where,
Now, plug in the given values and solve.
Therefore, the change in the potential energy is 700.7 J.
Answer:
D = 18000 kg/m3
V = 2.5*10{-7}m3
Explanation:
From the Archimedes principle,
Weight of fluid displaced = W_{air} - W_{water}
W_{air} = 4.5 gm
W_{water} = 4.25 gm
W = 2.4525*10{-3} N
D = 18000 kg/m3
b) object Volume can be obtained as ,
V = 2.5*10{-7}m3
Answer:
The equivalent capacitance will be
Explanation:
We have given two capacitance
They are connected in parallel
So equivalent capacitance
This equivalent capacitance is now connected in series with
In series combination of capacitors the equivalent capacitance is given by
So the equivalent capacitance will be
