A rocket is launching upwards. The force acting on the rocket to move upward is F. The forces acting opposite to thrust are weight and drag force. The drag force is due to the air resistance. In order to move upwards the thrust force must be greater than weight and drag force. Figure shows the free body diagram of rocket at the time of launching.There are only three forces: weight (always present), thrust (provided from the rocket’s engines to lift it up) and air resistance (said specifically to be not negligible). There are no horizontal forces.

That would be like dropping your cell phone on to the ground by accident. The object (cell phone)'s gravitational potential energy would be converted to kinetic energy or energy in motion more precisely. This is just a hypothetical example though.

Pls answer need help
igomit [66]

Answer:

See below

Explanation:

Find the NET forces on the objects

A  20==>

B    0

C  30==>

D  15==>    

So biggest accel = C because it has the most force acting on it

 next is A because it has the next biggest force

    next is  D        then    B ...B has no net force acting on it

What happens to a circuit's resistance as more resistors are added in series?
zysi [14]

It increases

Explanation:

A circuit's resistance increases as more resistors are added to it in series.

Series connection of circuit provides an additive increase in the resistance offered by the overall circuit.

A resistor is a device in a circuit that impedes the flow of electric current. It simply uses electric current.

Examples are bulbs, radio, television.

The more of these devices connected one to another in series, the more the resistance increases.
