If this is about simple machines the answer is: Inclined plane
Answer: Hope this Helps...
Explanation:
Force may be defined as the cause of motion and deformation. When a force is applied to an object, the object either moves or changes shape or both. In most cases, it is not possible to detect the deformation by naked eyes at the molecular or atomic level. Deformation occurs no matter how small.
For example, a car moving along a straight and horizontal highway, experiences an engine force Fe, while being opposed by an overall frictional force, Ff ( road friction as well as air resistance). If the car is moving to the right and to the right is taken to be the positive direction, then Fe acts to the right and Ff acts to the left. The net force is ΣF = Fe - Ff .
Answer:
Option A - Because of Newton's first law of motion
Explanation:
This is as a result of Newton's first law of motion.
Newton's first law of motion which is also referred to as the law of inertia states that; an object at rest will remain at rest and an object in motion will remain in motion with the same speed and in the same direction unless it's acted upon by an unbalanced force.
In this question, the car is at rest and it doesn't move because the upward force of the car is balanced by the downward pull of gravity. It can only move when an external force is applied to it. This fulfills Newton's first law of motion.
There are a pair of forces ... two of them ... between you and the computer.
You're attracted to the computer, and the computer is attracted to you.
The forces have equal strength.
Force of gravity = (6.67 x 10⁻¹¹ N-m²/kg²) M₁· M₂ / (distance)²
= (6.67 x 10⁻¹¹ N-m²/kg²) (80 kg) (4 kg) / (0.25 m)²
= (6.67 x 10⁻¹¹ x 80 x 4 N-m²) / (0.125 m²)
= 1.71 x 10⁻⁷ Newton
= about 0.000 000 615 ounce .
THAT's why you don't feel especially attracted to your computer.
