Answer:
it is constant because there is not any force that oppose the horizontal motion
but the vertical velocity is not constant because there is a gravitational force that oppose the motion .
Answer:
The Anti Reflective Coating on a solar cells helps to increase the amount of light absorbed into the cell. This anti reflective coating is very much needed as the reflection of a bare silicon solar cells is over 30%. For the thin AR Coating, silicon nitride or titanium oxide is used.
Explanation:
hope this help:)
D; it’s north magnetic pole would be pointing toward the geographic south pole
Answer:
Intensity Of MRI signal is related as square of 
or
Intensity is related as 
.
Explanation:
MRI simply means Magnetic Resonance Imaging. In this process by the resonance of magnetic field the frequency is produced which is used to image the body parts (Mainly the brain).
The signal Strength is the rate of change of Magnetization (M) with respect to the time. For the calculation of Intensity we use Bloch equation which is given by
On further solving
So, Intensity is related as .
Answer:
any 3 consequences of gravitational force are given below:
1) Planets revolve around the sun due to the gravitational force existing between them.
2) Sea tides occur due to the gravitational attraction of the Sun and the Moon.
3) Existence of solar system and galaxies.
