A person weighing 645 N climbs up a ladder to a height of 4.55 m. What is the increase in gravitational potential energy?

P.E = 2934.75

Explanation:

Potential energy can be defined as an energy possessed by an object or body due to its position.

Mathematically, potential energy is given by the formula;

Where, P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

Given the following data;

Weight =645

Height = 4.55

But we know that weight = mg = 645N

Substituting into the equation, we have;

Potential energy, P.E = 2934.75 Joules.

the answer is a)

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~
