Answer:
(a) The maximum conduction current is A
(b) Value of V
(c) Maximum value of
Explanation:
Given:
Radius of circular plates m
Separation between plates m
Frequency Hz
Maximum displacement current A
(a)
Displacement current is equal to the conduction current so we write,
A
(b)
From the formula of displacement current,
Where , peak value of emf,
V
(c)
From another formula of displacement current,
Where change in flux
Therefore, the maximum conduction current is A and value of
V and maximum value of
Answer:
The coefficient of kinetic friction = 0.026
Explanation:
An 56 kg sled is being pulled across the snow, at constant speed,by a horizontal force of 15 N.
Here we have to note that the weight is pulled at a constant speed . This means that the net force acting on the weight is zero.
The external force acting on the body is in the forward direction and the friction acts in the backward direction.
Friction increases as the mass of the body increases.
Friction =
We now equate this to the external force of 15 N.
15 =
=
= 0.026
The coefficient of kinetic friction = 0.026
Answer:
latent heat, also called the heat of vaporization, is the amount of energy necessary to change a liquid to a vapour at constant temperature and pressure. The energy required to melt a solid to a liquid is called the heat of fusion, and the heat of sublimation is the energy
Explanation:
Answer: water
The light reactions of noncyclic photophosphorylation takes place in the chloroplast.
The light energy is converted to chemical energy to produce both ATP and NADPH,
which act as energy-transfer molecules in the light-independent reactions of
the Calvin cycle. The addition of phosphate due to synthesizing of ATP by cells
results to photophosphorylation.
Moreover, <span>the electrons from water replenish chlorophyll molecules that
have given up electrons by photolysis. The two electrons from the water
molecule are kept in photosystem II, while the 2H+ and 1/2O2 are
left out for further use.</span>
