The most familiar non-contact force is gravity, which confers weight. In contrast a contact force is a force applied to a body by another body that is in contact with it. All four known fundamental interactions are non-contact forces: Gravity, the force of attraction that exists among all bodies that have mass.

The earth exerts a force of 500 newtons on an object what is the mass of the object in kg
guajiro [1.7K]

 Weight (that's what the 500 N is) = (mass) x (gravity) .

On Earth, gravity = about 9.8 m/s² , so

                                 500 N = (mass) x (9.8 m/s²) .

Divide each side by 9.8 m/s²: 

                                 Mass = (500 N) / (9.8 m/s²)

                                          =    51 kg  (rounded) .

Explain the bending of light as a property of a warping of space
saveliy_v [14]

Explanation:

According to the general theory of relativity, spacetime curves due to the energy it contains. Since mass is a form of energy, "create" gravity. That is, gravity is the effect observed as a consequence of the curvature of spacetime. Therefore, gravity curves the path of light because it curves the space through which light passes.

On a cloudless day, the sunlight that reaches the surface of the earth has an intensity of about W/m². What is the electromagnet
Otrada [13]

Answer:

1.907 x 10⁻⁵ J.

Explanation:

Given,

Volume of space, V = 5.20 m³

Assuming the intensity of sunlight(S) be equal to 1.1 x 10³ W/m².

Electromagnetic energy = ?

E = \mu V

E = (\dfrac{S}{c})\times V

where c is the speed of light.

E = (\dfrac{1.1\times 10^3}{3\times 10^8})\times 5.20

E = 1.907\times 10^{-5}\ J

Hence, Electromagnetic energy is equal to 1.907 x 10⁻⁵ J.
