Neveah’s mass on Earth is 79 kilograms (kg) and her weight on Earth is 110 pounds. The moon’s gravity is about 1/6 of the Earth’
mario62 [17]

Answer:

I believe the answer is A: Neveah's mass would stay the same but her weight would decrease

Explanation:

I believe its A because the moon has about 1/6 as much gravity as the Earth.  So if anything, her weight would decrease, not increase like B., C., or D says.  I hope this is helpful to anyone who reads it!!! ;)

How would you write this number in scientific notation? (Use the carrot key to denote an exponent. ex: 6.02 x 10^23)
NeTakaya

Answer:

D=5.89\times 10^{12}\ km

Explanation:

The distance to the Sun is 5,890,000,000,000. We need to write this distance in km.

A number can be written as x.0\times 10^y in scientific notation where x is a real no and y is any integer.

There are 10 zeros in the given number and also there are 12 digits after. It would mean that,

D=5.89\times 10^{12}\ km

So, the distance in scientific notation is : D=5.89\times 10^{12}\ km
