Answer:
Newton's Third Law
Explanation:
Newton's third law
Newton's third law: “for every action, there is an equal and opposite reaction.” This is where you get the bounce. When you push down on the trampoline (or fall downward onto the trampoline bed), Newton's third law says that an equal and opposite reaction pushes back.

Answer:
An object on the moon would weigh the LEAST among these. So correct answer is B.
Explanation:
- Weight of an object on any place is given by:
W = Mass * Acceleration due to gravity(g)
- It means when masses of different objects those are in different places are same, the weight of those objects depends upon the 'g' of that particular place.
- As we know, acceleration due to gravity on surface of moon (g') is 6 times weaker than the acceleration on surface of earth (g), which is due to the large M/R^2 of the earth than the moon.
i.e. g' = g/6 so W' = W/6
- And in the space between the two, the object is weightless.
For the same reason that you can skate around a curve at constant speed but not with constant velocity.
The DIRECTION you're going is part of your velocity, but it's not part of your speed.
If the DIRECTION changes, that's a change of velocity.
The object doesn't have to change speed to have a different velocity. A change of direction is enough to do it.
And any change of velocity is called acceleration.
I think its 980.7
because 9.807 × 100
Answer:
= 0.0298V
Explanation:
Electric field between two conductor = σ / ε₀
σ = 33pC/m²
= 33 × 10⁻¹²C/m²
ε₀ = 8.85 × 10 ⁻¹²C²/Nm²
E = 33 × 10⁻¹² / 8.85 × 10 ⁻¹²
= 3.7288N/C
potential difference between two conductors = Ed
where d = 8mm = 8 × 10 ⁻³m
V = 3.7288 × 8 × 10 ⁻³
= 29.83 × 10 ⁻³
= 0.0298V
