When is something weightless

Physics
1 answer:
valkas [14]3 years ago

The phenomenon of "weightlessness" occurs when there is no force of support on your body. When your body is effectively in "free fall", accelerating downward at the acceleration of gravity, then you are not being supported.

Why are the temperatures on each of the other terrestrial planets more extreme than earth?
netineya [11]
Other terrestrial planets have more extreme temperatures mainly because of their atmospheres
Explanation:
for example the atmosphere of Venus is composed mainly of carbon dioxide, this carbon dioxide traps the heat or energy from the sun and makes the planet have higher temperatures. where on mars the atmosphere is very thin so it takes in lots of heat and doesn't keep it in very well so it gets very hot and very cold

Example of an unbalenced force
lesya692 [45]

Answer:

Explanation:

unbalance force can be defined as the force that makes object slow up or down, in order words unbalanced force can be  defined as anything that can alter the state of motion of an object.

an example of an unbalanced force is likened to a situation of someone inside a lift going for a meeting at the top floor, the force which propels the lift upward is unbalanced, because it is greater than the force acting on the lift.

Two small identical metal spheres, A and B, on insulated stands, are each given a charge of +2.0 x 10-5 coulomb. The distance be
SpyIntel [72]

Answer:

a) 90 N

Explanation:

Coulomb's law: states that the electric force of attraction or repulsion between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

It is represented mathematically as

F = 1/4πε₀(q₁q₂)/d²......................... Equation 1

Where F = Electrostatic force, q₁ = charge on the first metal sphere, q₂ = charge on the second metal sphere, d = distance between the spheres, 1/4πε₀ = proportionality constant.

<em>Given: q₁ = +2.0×10⁻⁵ C, q₂ = 2.0×10⁻⁵, d = 2.0×10⁻¹ m</em>

<em>Constant : 1/4πε₀ = 9×10⁹Nm²/C²</em>

<em>Substituting these values into equation 1,</em>

<em>F = (9×10⁹×2.0×10⁻⁵×2.0×10⁻⁵)/(2.0×10⁻¹)²</em>

<em>F = (9×4×10⁻¹)/4×10⁻²</em>

<em>F = 90 N</em>

Therefore the electrostatic force is = 90 N

The right option is a) 90 N
