Answer: The correct answer is "weight".

Explanation:

The expression for the weight is as follows;

w= mg

Here, m is the mass of the object, g is the acceleration due to gravity and w is the weight.

Weight: It is the force which is exerted by the gravity on an object. It varies place to place.

The weight of the object depends on mass and acceleration due to gravity.

The weight of the object on the moon is one sixth of the weight of the object on the earth whereas the mass of the object remains constant.

Density is defined as the mass per unit volume.

Therefore, the force that gravity exerts on an object is called weight.

Using the given equation you get:

E = 1.99x10^-25 / 9.0x10^-6

Divide 1.99 by 9.0: 1.99/9.0 = 0.22

For the scientific notation, when dividing subtract the two exponents:

25 -6 = 19

So you now have 0.22 x 10^-19

Now you need to change the 0.22 to be in scientific notation form:

2.2 x 10^-20

The answer is B.

Which explanation best describes a wave?
Gekata [30.6K]

Answer:

C. a disturbance that travels through a medium with a transfer of energy and without a transfer of matter

Explanation:

A wave is any disturbance that transfers energy from one location to the other via a substance called medium. It is important to note that a wave only conveys energy and not matter. For example, sound wave is a type of wave that carries sound energy from one place to another via mediums such as water, air etc.

Hence, according to this question, a wave can be described as a disturbance that travels through a medium with a transfer of energy and WITHOUT A TRANSFER OF MATTER.
