An object of mass 0.93 kg is initially at rest. When a force acts on it for 2.9 ms it acquires a speed of 16.9 m/s. Find the magnitude of the average force acting on the object during the 2.9 ms time interval.

If a sphere and a cure have the same mass and are propelled up a ramp with the same force, which would travel father up the ramp? explain.

Why does lightning travel from clouds to the ground?

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b. b. at twice the distance, the magnitude of the field is 2b. c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
