Earth's gravity and the satellite's velocity keeps it so that it stays in orbit. (there is a more complicated side, too...)
Answer:
Troposphere
High-pressure areas form due to downward motion through the troposphere, the atmospheric layer where weather occurs.
Answer:force is an agent which change the state of rest or uniform motion of a body. The unit of force newton
Explanation:
Force is that which change the state of rest or uniform motion of an object.the unit of force is newton or kgm/s^2
Answer:
Change in momentum will be -4.4 kgm/sec
So option (A) is correct option
Explanation:
Mass of the ball is given m = 0.10 kg
Initial velocity of ball 
And velocity after rebound 
We have to find the change in momentum
So change in momentum is equal to
( here negative sign shows only direction )
So option (A) will be correct answer
Electrical shock is most likely to be fatal when the path of the current is through the heart.
