Answer:

Hi there!

Your answer is D. Halfway up the peak

Explanation:

Think of potential energy like you are a marble. If a marble is at the peak of the hill, it's potential energy is ENORMOUS because as gravity pulls it downward it will increase in speed. Halfways down the peak is about the same potential energy as the peak, although slightly less. At the end of the climb, we can assume the landscape flattens out. This means there's very little pull to make it change at all. It will continue with the speed gained from the downhill trajectory until something in its environment stops it (such as friction). When a marble is at the bottom of a large hill, the potential energy is low. It takes a lot of force to try and get up the hill, losing lots of energy

I hope this makes sense!

Explanation:

Gravitational potential energy = mgh, where m is the mass of the mountain climber, g is the gravitational force and h is the height from the base.

Since m and g are constants, the climber's potential energy will be the lowest when he's at the end of the climb, at the base of the mountain. (B)

expeople1 [14]

Answer

a balance and a graduated cylinder

Explanation

Density is mass per unit and it is property  characteristic of a substance. The arrangement of the mass of atoms and their size is what determines the the density of a substance.

For a student to measure the density of seawater  he/she is required to use a balance and a graduated cylinder where a balance will be used to measure the mass of the mineral sample  and then a graduated cylinder to determine the volume.
