Assuming conservation of energy:
Energy before = 7000 + 4000 = 11 000 MJ
Energy after = 2000 + Kinetic = 11 000
Therefore Kinetic = 11 000 - 2 000
Kinetic = 9 000 MJ
Answer:
Explanation:
Polarization In this case angle of incidence is not equal to angle of polarization, hence reflected light is partially polarized and transmitted light is also partially polarized. by reflection is explained by Brewster's law,
According to this when unpolarized light incident on glass plate at an angle is called as angle of polarizing the reflected light is plane polarized, and transmitted light is partially polarized. The plane of vibration of polarized light is having plane of vibrations perpendicular to plane of incidence.
Answer:
B
Explanation:
The control is something that is meant to not be changed, the control is a comparison of the experimental.
We have that the cricket’s displacement is

From the Question we are told that

Answer and Explanation:
Hydrostatic equilibrium is the condition in which force is balance that is upward force and downward force the downward force is due to gravitational force and the upward force is due to the pressure. The Sun is said to be in hydrostatic equilibrium means the force acting on it is balance means upward force which is due to pressure is same as the force exerted by gravitation.
