Explanation:
It is given that, two teams are playing tug of war.
Force applied by Team A, 
Force applied by Team B, 
We need to find the net force acting on the rope. It is equal to :
So, the net force acting on the rope is 35 N and it is acting toward right. Hence, this is the required solution.
Answer:
a. 
b. 
c. 
Explanation:
Use Gravitational Force:
Use values given to have the results.
b.
Use m as the mass of the Moon. Using values of a. and m you have the answer.
c.
Use M mass of the planet. Use value of a and Mass of Planet.
<u>Answer:</u>
"Where friction or rubbing results in the transfer of electrons between particles, objects can become negatively or positively charged."
<u>Explanation:</u>
The motion resistance of one moving object with respect to another is called as "Friction". It isn't a basic force, like gravity or electromagnetism. Alternatively, scientists believe it is the product of the electromagnetic attraction in two touching surfaces between charged particles.
The friction have formula:
Friction force (<em>f </em>) = coefficient of friction × normal force (N)
For an instances when one ride a bicycle, an example of rolling friction is the contact between the wheel and the way.
I believe the two ways to increase an object’s potential energy, is either by an object’s placement or by an object moving up a gradient. So the higher the object is according to its initial height, the higher the potential energy. And when an object is at a constant velocity moving up a hill, the gravitational potential is increasing, while the kinetic energy is decreasing.
