Answer:
All the objects experience the same acceleration
Explanation:
According to Newton's law of universal gravitation, we have the gravitational force F given by the relation;
Where;
G = The universal gravitational constant
M₁ = The mass of the Earth
m₂ = The mass of the object in the Earths gravitational field
R = The radius of the Earth
Therefore, we have;
Which gives;
Therefore, based on the above calculation, all three object will have the same acceleration due to gravity, g, when air resistance is ignored.

Answer:
option B
Explanation:
The correct answer is option B
Effective capacity is the capacity of a firm to achieve the given target will all the constraints .
Effective capacity of an company can be calculated by actual capacity divided by the efficiency of the company.
it can be explained by an example
Assume the capacity of company to produce toy is 49 per hours and the efficiency of the production is 70 %
so the effective capacity will be equal to 49/0.7 = 70
hence, effective capacity will be 70
Answer:
1. 2 N to the left
2. To the left.
Explanation:
1. Determination of the net force.
Force applied to the right (Fᵣ) = 18 N
Force applied to the left (Fₗ) = 20 N
Net force (Fₙ) =?
The net force acting on the book can be obtained as follow:
Fₙ = Fₗ – Fᵣ
Fₙ = 20 – 18
Fₙ = 2 N to the left
Thus, the net force acting on the book is 2 N to the left
2. Determination of the direction.
From 1 above, the net force acting on the book is 2 N to the left. This simply means that the book will move to the left direction.
