Answer:
The force between the Earth and the object is, F = 9.61 x 10⁻¹² N
Explanation:
Given data,
The mass of the Earth, M = 5.9 x 10²⁴ kg
The mass of the object, m = 10 kg
The gravitational force between the earth and the object is given by the formula,
F = G Mm/R²
Substituting the given values in the above equation,
F = 6.673 x 10⁻¹¹ x 5.9 x 10²⁴ x 10 / 6.4 x 10⁶
= 9.61 x 10⁻¹² N
Hence, the force between the Earth and the object is, F = 9.61 x 10⁻¹² N
Answer:
A circuit which has a battery in it will not allow electricity to flow through it. A device called a switch can be used to complete a circuit so that other devices can be switched on or off.

Answer: It's the third one.
Explanation:
The horizontal force applied is 160 N while the velocity is 2.03 m/s.
<h3>What is the speed of the car?</h3>
The work done by the car is obtained as the product of the force and the distance;
W = F x
F = ?
x = 30.0 m
W = 4,800 J
F = 4,800 J/30.0 m
F = 160 N
But F = ma
a = F/m
a = 160 N/2.30 ✕ 10^3-kg
a= 0.069 m/s
Now;
v^2 = u^2 + 2as
u = 0/ms because the car started from rest
v = √2as
v = √2 * 0.069 * 30
v = 2.03 m/s
