A projectile is launched with a speed of 10m/s at an angle 30 degrees from the positive x axis. What is the range of the projectile?

8.82 m. The 'range' means the distance along the positive x axis travelled by the projectile during its flight. First calculate the time elapsed over the flight using the SUVAT equation y = usin(θ)t - 0.5...

If a car is traveling at a speed of 10m/s. The driving force of 500N is required to keep the speed constant . What is the power supplied by the engine?

In the question we are given:Speed=10m/sForce=500NPower is work done per second and also the force times velocity.(could discuss how this works in units: W=J/s = Nm/s therefore Joules = Newton-meters )So ...

A coil is connected to an analogue centre zero ammeter. A magnet is dropped (North pole first) so that it falls vertically and completely through the coil. What would be observe on the ammeter?

The ammeter's needle would first be deflected one way, then as the direction of the current reversed, it would deflect the other way.
