What is an astronomical unit or AU?

Biology
1 answer:
hichkok12 [17]3 years ago
7 0

Answer:

B

Explanation:

The correct option should be B.

The Astronomical Unit, AU, is a measurement unit for length in general astronomy and represents the mean or the average distance of the sun from the earth.

Mathematically, in astronomy,

1 astronomical unit = 150,000,000 km

But then, 1 km = 0.621371 mile

Hence,

150,000,000 km = 150,000,000 x 0.621371 miles

            ≈93,000,000 miles

Therefore, 1 astronomical unit can also said to be approximately equal to 93,000,000 miles.

<u>The correct option is B</u>

A 2-kg bowling ball sits on top of a building that is 40 meters tall.
Alchen [17]
Okay, so this is physics. What is the meaning of KE? It's Kinetic Energy. What is the meaning of GPE? It's Gravitational Potential Energy. So how do you calculate either, and what are their significances? Kinetic -> motion, Gravitational potential energy -> energy that can be used to do work due to gravity. So is the bowling ball moving, or is it someplace it can fall from, or both?

Kinetic energy is calculated as 1/2 * mv^2, where m is the mass of the object, and v is the velocity. Potential energy for conservative forces is the product of the force and the distance over which it can do work. Thus in the case of GPE, it is the weight multiplied by the height, as gravity is a conservative force. What is the weight? It's not equal to the mass.

Hopefully these hints will get you thinking.
