Answer:
Do = density of obect Dw = density of water
Weight of object = V g Do
Weight of water = V g Dw
F = m a = V Do a = V g Do - V g Dw
Acceleration of object = mass * force on object
Do (g - a) = Dw g
Do = Dw ( 1 / (1 - a / g) = 1000 * 1 / (1 - 3.75 / 9.80) kg/m^3
Do = 1441 kg / m^3
If no acceleration then density of object = density of water
A balanced force is upon it because balanced means both sides are equal so they cancel each other out, while unbalanced means one side is weaker/stronger than the other and in this case its in a state of rest so the net force would be equal/balanced.
I am pretty sure it's solids
The orbital speed of the space shuttle is 2.12 x 10⁴ m/s.
<h3>
Orbital speed of the space shuttle</h3>
The orbital speed of the space shuttle is calculated as follows;

where;
- G is gravitational constant
- M is mass of the Earth
- r is the distance from the center point of the planet

Thus, the orbital speed of the space shuttle is 2.12 x 10⁴ m/s.
