I have been teaching chemistry for the last 2 years.
An electric bulb draws a current of 0·2 A when the voltage is 220 volts. Calculate the amount of charge flowing through it in one hour.
How much net force is required to accelerate a 1000 kg car at 4.00 m/s2?
If you apply a net force of 3 N on 1 kg-box, what is the acceleration of the box (a) 2 m/s2 (b) 30 m/s2 (c) 10 m/s2 (d) None of these.
A body of mass 1 kg undergoes a change of velocity of 4m/s in 4s what is the force acting on it?
If a net force of 7 N was constantly applied on 400 g object at rest, how long will it take to raise its velocity to 80 m/s?
A sedan car of mass 200kg is moving with a certain velocity . It is brought to rest by the application of brakes, within a distance of 20m when the average resistance being offered to it is 500N.What was the velocity of the motor car?
