Answer:
1.33×10⁻¹⁰ N
Explanation:
F = GMm / r²
where G is the gravitational constant,
M and m are the masses of the objects,
and r is the distance between them.
F = (6.67×10⁻¹¹ N/m²/kg²) (1000 kg) (2000 kg) / (1000 m)²
F = 1.33×10⁻¹⁰ N
Answer:
This question appear incomplete
Explanation:
This question appear incomplete. However, the density of water is generally known to be 997 kg/m³. The formula used to determine density is mass ÷ volume. In the case of the density of water, the mass is measured in kilograms (kg) while the volume is measured in cubic meter (m³).
Answer:
The value is
Explanation:
Generally the moon's radial acceleration is mathematically represented as
Here
is the angular velocity which is mathematically represented as

substituting
for T(i.e the period of the moon ) we have
=>
From the question r(which is the radius of the orbit ) is evaluated as

substitute
for R and
H

=> 
So
