PLZ HELP?!! A mountain climber starts at the base of a mountain, climbs all the way to the peak, and then climbs back down to the base. At which point is the climber's potential energy the lowest?
A. At the peak
B. At the end of the climb
C. Halfway down from the peak
D. Halfway up to the peak
EXPLAIN PLZ

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)

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!

cuz he's blad

gregor john mendel is known for study of inheritance in pea plants. he used garden pea plant for his study, having alternative traits for various characters. he performed cross-breeding in pea plants to check how characters are transmitted between parents to offspring, such as cross between pure tall and pure dwarf plant. mendel studied the inheritance patterns in pea plants for various generations.

thus, the correct answer includes options and f).
