Explanation:
The orbit of the planet is considered to be stable and does not change over time. This means that the force of gravity and inertia are perfectly balanced. Leading to forward motion of Planet and moons under force of gravity of some other large body(Most probably stars).This is in turns leads to formation of orbit.
Answer:
C.Earth and you exert equal and opposite forces on each other.
Explanation:
Hello, I can help you with this
The force that the earth exerts on any object is due to the force of gravity and is known as weight, F = mg, this force is directed towards the center of the earth, in addition, according to the laws of physics for any action must have a reaction, in this case it is a force that goes out from the ground and it is directed upwards, this force is called normal and it has the same magnitude of your weight but the opposite direction.
Have a great day.
Answer:
The acceleration of the refrigerator is 
Explanation:
The expression of the equation of the net force acting on the refrigerator is as follows;
F-f= ma
Here, F is the applied force, f is the force of friction, m is the mass and a is the acceleration.
It is given in the problem that you're having a hard time pushing a refrigerator having mass 355 kg across the kitchen floor. The force of your own push is 993 N. The force of friction opposing your own push is 973 N.
Put F= 993, f= 973 N and m = 355 kg in the above expression of the equation to calculate the acceleration of the refrigerator.
993 - 973 = (355)a
20 = 355 a
Therefore, the acceleration of the refrigerator is .

The Answer is 0.019998c
Explanation:
Please see the attached Picture for the answer.
Answer:
256 x 10³ Nm
Explanation:
Force on each of the charges of 8 C due to uniform electric field in x -y plane will be equal and opposite because one is positive charge and the other is negative charge. They will make a couple
Each of the forces of the couple will act in x - y plane and will be equal to
F = Q E = 8 X 8 X 10³
= 64 X 10³ N
Arm of the couple = 4 m
Moment of couple about z axis.
= 64 x 10³ x 4
= 256 x 10³ Nm.
