Explanation : We know that two forces acting on the satellite.
The speed of the satellite and the force of the gravity on the satellite then the result , the satellite moves around the earth in a circular motion.
A satellite to move tangentially to a circular path, while revolving around the circular path because the centripetal force is acting on it.
So, we can say gravity is responsible for the motion of the satellite in a circular path.
Dominoes does because when you hit one, it knocks over the next one, and so on, so forth. The same type of pattern happens in a wave.
Answer:0.114 C
Explanation:
Given
Total 4.7 C is distributed in two spheres
Let 
and 
be the charges such that
and Force between charge particles is given by
put the value of
thus 
Explanation:
When the wire is connected to a battery, the compass needle moves and changes its position. This happens because the needle magnetizes the copper wire, thus, creating a force.
While the current in the wire produces a magnetic field and exerts a force on the needle. The insulation on the wire becomes energized and exerts a force on the needle. Hence, the compass needle moves and changes its position.
