Answer:
9.81N
Explanation:
the force of attraction is given by
F=<u>GmM</u><u>/</u><u>R²</u><u> </u>
where m is mass of the body
M is mass of the earth
R is radius of the earth
G is the universal gravitational constant(6.67x10-¹¹)
hence we substitute the values in the formula.

Answer:
The absolute pressure of air inside the tank is 164.7 psi.
Explanation:
Given that,
Atmospheric pressure = 14.7 Psi
Gauge pressure = 150 psi
We need to calculate the absolute pressure of air inside the tank
Using formula of absolute pressure
Where, = gauge pressure
=atmospheric pressure
Put the value into the formula
Hence, The absolute pressure of air inside the tank is 164.7 psi.
Answer:
Explanation:
When the two or more forces acting on a body such tat the net force on the body or the acceleration of the body is zero, then such forces are balanced forces.
For example, in the game of tug of war, both the teams pulls the rope with same force but in opposite directions so that the net acceleration is zero it means a balanced force is acting on the rope.
When tow or more forces acting on a body and there is some net force or acceleration of the body, then the forces are said to be unbalanced.
For example, if we push a box along the plane, the net force is non zero and the forces are unbalanced.
