Aunt Jane weights 45 Newtons. What is her mass?
RUDIKE [14]

Answer:

10.116 Pounds/45 newtons = 10.1164024 pounds/force

Explanation:

Divide the newtons by the rate of acceleration, which will give you the mass of the object. The mass will be in kilograms, because a single newton represents the amount of force needed to move one kilogram one meter. For our example, we will divide 10 N by 2 m/s/s, which give us a mass of 5 kg

if the moon were somehow knocked out of orbit and flew off into outer space, what are the possible effects on the earth?
Anarel [89]
<h2>Answers:</h2>

<u>The possible effects on the earth will be</u><u> 1) No light during night 2) No tides</u>

<h2>Explanation:</h2>

As we know that tides are caused by the differential gravitational force on the equatorial regions by the moon. So if the Moon escapes from Earth, the main effect would be the lack of tides on Earth The region closer to the Moon experiences more gravitational force than the region on Earth away from the Moon. Other effects will be no more Moon to light up the night sky and no more solar eclipses.
