Answer: i think its local drive
Explanation:
It would be kinetic energy. Let's say the book is weighs 10 Newtons you need to use a force of 10 Newtons to lift the book. In other words it's positive. As you move the book you're giving it energy. Namely potential energy which will turn to kinetic energy if you let it go. So you're changing it's position and energy.
Answer:
-0.9 m/s²
Explanation:
Given:
Δx = 500 m
v₀ = 50 m/s
v = 40 m/s
Find: a
v² = v₀² + 2aΔx
(40 m/s)² = (50 m/s)² + 2a (500 m)
a = -0.9 m/s²
Answer:
if a star is moving towards earth it is blue shifting
Answer:
It would be (a)
Explanation:
A theory is something that can be proved through rigorous and repeated experimentation, while choice (b) sounds tempting i believe it fails at the fact that it says that a theory is an "agreement", sure an agreement could be reached by while trained scientists but that does not necessarily mean that what the scientists agree upon is rigorously tested and repeatable, and so therefore cannot be assumed
That is what I think
Hope this helps :)
