A chair is pushed forward with a force of 185 N. The gravitational force of earth on the chair is 155 N downward. The force of f

riction acting on the chair is 55 N. Draw a free-body diagram showing all forces acting on the chair. Determine the magnitude of any missing force values AND determine the net force acting on the chair.

The net force on the chair is 100N

<u>Explanation:</u>

The free body diagram is attached below.

According to the condition,

when a downward gravitational force of 155N of earth acts then an equal opposite upward force of same magnitude also acts on the chair.

Therefore, the normal force acting on the chair is 155N

When a chair is pushed forward on a surface, then a frictional force also acts on it in opposite direction.

The net force acting on the chair is = F - f

Where,

F is the applied force

f is the force of friction

Net force = 155N - 55N

Fnet = 100N

Therefore, net force on the chair is 100N

a flashlight has a resistance of 2.4 ohms. what voltage is applied by the batteries if the current in the circuit is 2.5A?
Mashcka [7]

E = I R

That means 

        Voltage = (current) x (resistance)

                     =   (2.5 A)  x  (2.4 ohms)

                     =       6 volts .
