Two parallel wires A and B 10cm apart and carry currents of 10 A and 6 A respectively. Find the force on a 2.0 m length of wire B, if the currents are in the same direction
A cylinder of mass m and radius R has a moment of inertia of . The cylinder is released from rest at a height on an inclined plane, and rolls down the plane without slipping. What is the velocity of the cylinder when it reaches the bottom of the incline?
1. A 400.0-N sign hangs from the end of a uniform strut. The strut is 4.0 m long and weighs 600.0 N. The strut is supported by a hinge at the wall and by a cable whose other end is tied to the wall at a point 3.0 m above the left end of the strut. Find the tension in the supporting cable and the force of the hinge on the strut.
What is the angular acceleration of a ball that starts at rest and increases its angular velocity uniformly to 5 rad/s in 10 s?
What should be the angle of incidence of a light ray incident through air on the boundary separating air from water so that the angle of refraction is 30°? (refractive index of air is 1 and that of water is 1.32)
A copper calorimeter weighs 100g when empty and 500g when half filled with water at 20oC 50g of dried ice are added and the final temperature of the mixture after all the ice has melted is 10oC. Calculate the specific latent heat of melted ice.
30g of metal at 90oC is placed at 20oC in a calorimeter of mass 70g made of the same metal. If the final temperature is 22.1oC. Calculate the specific heat capacity of the metal.
an object has a final velocity of 10m/s an initial velocity of 5m/s and an acceleration of 3m/s2.calculate the distance covered by this object in its motion.
