Q1. Two cars are travelling on a dirt road between 3 consecutive poles after 5.40s they are side by side at next telephone pole. The distance between the poles is 66.30m.
Q2. A runner is planning for a 10km race. She can preserve a steady speed of 3.9 m/s for as much time as essential before ending the race with a 7.90 m/s sprint. If she wants to finish in 40 min or less, how far from the finish should she begin to sprint?
The aurora is caused when electrons and protons, moving in earth's magnetic field of 5x10^-5 T, collide with molecules of the atmosphere and cause them to glow. What is the radius of the circular orbit for (a) an electron with speed 1.0×10^6 and (b) ..
If air resistance & other effects are ignored how far away did the shell hit.
An air-filled capacitor is formed from two long conducting cylindrical shells that are coaxial and have radii of 37 mm and 92 mm. The electric potential of the inner conductor regarding the outer conductor is -574 V.

Monochromatic light from a distant source is incident on a slit 0.750 {rm mm} wide. On a screen 2.00 {rm m} away, the distance from the central maximum of the diffraction pattern to the first least amount is measured to be 1.35 {rm mm}.
One side of the roof of a building slopes up at 34.0°. A student throws a Frisbee onto the roof. It strikes with a speed of 15.0 m/s and does not bounce, but slides straight up incline. The coefficient of kinetic friction between plastic and roof is ..
What is the minimum rate of rotation, in revolutions per minute, required for the spheres to contact the cylinder wall?
A 0.04 kg bullet collides in elastically with a 0.5 kg ballistic pendulum. Before the collision the pendulum was at rest but immediately after collision the pendulum is moving with speed of 13.6 m/s. How fast was the bullet travelling before the coll..
