Answer:
An object in equilibrium has a net force of zero
Static equilibrium describes an object at rest having equal and balanced forces acting upon it.
Dynamic equilibrium describes an object in motion having equal and balanced forces acting upon it.
Explanation:
An object is said to be in equilibrium when a net force of zero is acting on it. When this condition occurs, the object will have zero acceleration, according to Newton's second law:
where F is the net force, m the mass of the object, a the acceleration. Since F=0, then a=0. As a result, we have two possible situations:
- If the object was at rest, then it will keep its state of rest. In this case, we talk about static equilibrium.
- If the object was moving, it will keep moving with constant velocity. In this case, we talk about dynamic equilibrium.
Answer:
new force is 6 times of the initial force.
Explanation:
Let the charges on two objects is q₁ and q₂. The electric force between charges is given by :
Objects 1 and 2 attract each other with a electrostatic force of 18.0 units
If the charge of Object 1 is doubled and the charge of object 2 is tripled, it means, 
and 
. New force is given by :
So, the new electrostatic force between objects will become 6 times of the initial force.
A advantage is less car accidents and a disadvantage is, in order to keep the roads clear of ice is a chemical. Like salt. Which is bad for the animals.
Gravity is an attractive force that works to pull objects together. If 2 objects are close the gravitational pull will be stronger
Mass and distance determine gravity. The farther two things are away from each other, the weaker the gravitational forces are, the less mass an object has the less gravitational force it exerts
That type of bending is called "diffraction" of waves.
