<h2>
Answer: Gravity force</h2>
If we approximate the orbit of the planets around the Sun to circular orbits with a uniform circular motion, where the velocity 
is a vector, whose direction is perpendicular to the radius 
of the trajectory; the acceleration 
is directed towards the center of the circumference (that's why it's called centripetal acceleration).
Now, according to Newton's 2nd law, the force 
is directly proportional and in the same direction as the acceleration:
Therefore the net force resulting from the movement of a planet orbiting the Sun points towards the center of the circle, this is called Centripetal Force which is a central force that in this case is equal to the gravity force.
Answer:
<h3>The 28 loops wound on the square armature</h3>
Explanation:
Peak output voltage 
V
Area of square armature 
Magnetic field 
T
Angular frequency 
According to the law of electromagnetic induction,
Where 
number of loops of wire.
≅ 28
Thus, 28 loops of wire should be wound on the square armature.
"Saturn". It is largest moon of Saturn.
In short, Your Answer would be Option B
Hope this helps!
Answer:
Explanation:
We have,
Mass of Mars is, 
Mass of its moon Phobos, 
Distance between Mars and Phobos, d = 9378 km
It is required to find the gravitational force between Mars and Phobos. The force between two masses is given by
Plugging all values, we get :
So, the gravitational force is 
.
