Answer:

Option B

Explanation:

The fundamental quantities are the basic quantities from which other quantities are derived.

There are a total of 7 fundamental quantities, namely Length, Mass, Time, Luminous Intensity, Amount of substance, Electric Current, Temperature.

From these 7 quantities, the other quantities are derived.

Weight is the product of its mass and the gravitational acceleration 'g' which acts on that mass.

Where mass is the fundamental quantity and 'g' is also derived and hence weight is a derived quantity.

If your asking about the total amount of time the sun is visible, it will be equal over the course of a year. In Nome, Alaska, it will be daylight almost 24 hours a day in the summer and be dark almost 24 hours a day in the winter. In San Diego they are much closer to the equator and will receive sunlight roughly the same amount each day all year long. In the end these times will add up to the same amount.

However if you are asking about intensity of sun light received, San Diego will get considerably more since its near the equator and its getting almost direct sunlight. In Nome, the sunlight is hitting the earth at an angle so fewer rays of light are hitting the ground per square foot.

Digiron [165]

Answer:

Melting

Explanation:

The process of a solid becoming a liquid is called melting. (an older term that you may see sometimes is fusion). The opposite process, a liquid becoming a solid, is called solidification. For any pure substance, the temperature at which melting occurs—known as the melting point—is a characteristic of that substance.

Why does an object in motion stay in motion unless acted on by an unbalanced force?
Svet_ta [14]

Answer: A) because forces are what stop and start motion

Explanation:

From Newton's first law, an object tends to stay in state of rest or motion unless acted upon by an unbalanced external force. This is also known law of inertia. This is because a force can stop or start a motion. A force cause body to accelerate to decelerate otherwise the body continues with constant speed.
