A chemical property is a change in classification in matter I think
Think about the formula for potential energy. (Surely you remember it):
Potential energy = (mass) x (acceleration of gravity) x (height)
-- The mass on the end of the pendulum doesn't change.
-- The acceleration of gravity doesn't change.
-- The only thing that changes is the height of the mass on the end.
So the potential energy is lowest when its height is the lowest.
That's position <em>B </em>.
Answer:
A. The speed of the wave increases four times.
Answer:
2 : A large storm
Explanation: I hope this helps
Answer:
From the relation above we can conclude that the as the distance between the two plate increases the electric field strength decreases
Explanation:
I cannot find any attached photo, but we can proceed anyways theoretically.
The electric field strength (E) at any point in an electric field is the force experienced by a unit positive charge (Q) at that point
i.e

But the force F

But the electric field intensity due to a point charge Q at a distance r meters away is given by
