How long can a flashlight run for if it draws 0.11 amps and its battery contains 10 coulombs of change?

Battery will run for t = 90 s

Explanation:

As we know that rate of flow of charge is known as electric current

So we will have

now we have

its c its is a mixture of gases

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
