Answer:
(C) line integral along a closed loop
This integral is evaluated by dividing the path into infinitesimal segments dL, calculating the scalar product B•dL for each segment, and sum these products. The component of B parallel to dL at each point is always used in evaluating this integral.
The line integral is equal to mu_o × I.
Explanation:
The correct answer to the question is D). Kinetic to electrical.
EXPLANATION:
Hydro electric power plants are the electricity generation plants which capture the energy of falling water to produce current.
The water present at the top of a dam has potential energy. When the water is allowed to fall from certain height, the potential energy of the water is converted into kinetic energy.
The falling water moving with high speed is allowed to fall on a turbine. The kinetic energy of the water will rotate the turbine. The turbine is attached to a generator which will produce electricity due to the electromagnetic induction.
Hence, we see that the kinetic energy of the water is converted into electric energy.
Answer:
a)1396.52 N
b)1396.52 N
c)
d)
Explanation:
The force experienced by the satelite is giveb by

m_{satellite}= 445 Kg
m_{earth}= 6×10^24 Kg
radius r= 1.77Re= 1.77×6.38×10^6 m
now putting values we get

⇒F= 1396.52 N
now,



also,
