Answer:
kettles: holes left by glaciers.
cirques: three-sided valleys
erratics: large, out-of-place rocks bouldersleft by glaciers.
drumlins: egg-shaped hills
Explanation: APEX
Answer:
it could be either or because it doesnt just depend on the height but it also depends on the pressure but then again the question didnt ask anything about the pressure so the answer should be true
Explanation:
The initial force between the two charges is given by:

where k is the Coulomb's constant, q1 and q2 the two charges, d their separation. Let's analyze now the other situations:
1. F
In this case, q1 is halved, q2 is doubled, but the distance between the charges remains d.
So, we have:

So, the new force is:

So the force has not changed.
2. F/4
In this case, q1 and q2 are unchanged. The distance between the charges is doubled to 2d.
So, we have:

So, the new force is:

So the force has decreased by a factor 4.
3. 6F
In this case, q1 is doubled and q2 is tripled. The distance between the charges remains d.
So, we have:

So, the new force is:

So the force has increased by a factor 6.
Power = work/time
Work = force * distance
(2000 N * 200 m) / 10 s = 40,000 Joules
