The acceleration of gravity in low Earth orbit is a fraction smaller than it is on the Earth's surface, like maybe 15% less.
The astronauts feel no gravity at all, because they and everything around them are constantly falling.
Answer:
The ratio is
Explanation:
From the question we are told that
The period of the satellite is
Generally the period of earth around the sun is
Generally from Kepler's third law , which is mathematically represented as
Here is the radius of the orbit which the satellite rotate around the sun
is the radius of the orbit which the earth rotate around the sun
=>

Answer:density
Explanation:
At the bottom, deep bodies of water always measure because at that temperature water has it highest density .
In water bodies like lake warm water rises up due to convection and at higher depths there is cold water, which is found to be at highest density of water.
When water molecules acquired heat energy it become widely spread at the same volume and thus posses low density but at low temperature water molecule occupy less space therefore posses maximum density at
I looked up the speed of sound in water ... you could have done it,
but I did it for you. It said 1,484 m/s ... I don't know if that's for fresh
water or sea water, but for 5 points I'm not going to worry about it.
Time = (800 meters) x (1 sec / 1,484 meters)
= (800 x 1,484) seconds
= 0.539 second . (rounded)
The first choice on the list is the closest one.
