Question 11 of 35
Which characteristic is related to potential energy but not kinetic energy?
O A. An object's height
B. An object's speed
C. An object's mass
ОО
D. An object's velocity

Answers

Answer:

its A the object's height

Explanation:

Answer:

A. An object's height

Explanation:

Energy can be defined as the ability (capacity) to do work. The two (2) main types of energy are;

a. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.

Mathematically, kinetic energy is given by the formula;

[tex] K.E = \frac{1}{2}MV^{2}[/tex]

Where;

K.E represents kinetic energy measured in Joules. M represents mass measured in kilograms. V represents velocity measured in metres per seconds square.

b. Potential energy (PE): it is an energy possessed by an object or body due to its position above the earth.

Mathematically, potential energy is given by the formula;

[tex] P.E = mgh[/tex]

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.

Hence, the characteristic that is related to potential energy but not kinetic energy is the height of a physical object.

Which of the following happens as you get further North or South from the Equator?

a Seasons reverse
b Time zones change
c Climate gets warmer
d Climate gets cooler

Answers

It decreases. Because the time the sun is above the equator is maximum at the equator and the time to cool off is minimum. Consider an extreme. At the extreme north/south travel of the sun, it only touches near each pole once per year. Then there is a whole year to cool off as the sun goes to the opposite extreme and back again. If you go a little south of the northern extremity of travel or a little north of the southern extremity, it is a little warmer because the exposure to the sun is not at the extreme minimum. At the exact center of travel, the equator, the maximum time away from that point is the minimum for any location on earth.
