An ice-skater with a mass of 75.0 kg pushes off against a second skater with a mass of 42.0 kg.
Both skaters are initially at rest.
After the push, the larger skater moves off with a speed of 0.75 m/s eastward.
What is the velocity (magnitude and direction) of the smaller skater after the push?
A 25 N box is pulled vertically upward by means of a cord.Find the acceleration of the box if the tension in the cord is 35 N.
Ultraviolet catastrophe: A shortcoming of the Rayleigh-Jeans formula, that tries to explain the radiancy of a blackbody at several frequencies of the electromagnetic spectrum.
Uses of Radar: Radar is used to locate and recognize war planes and missiles, to guide ships or submarine to see position of a satellite in space.
Micrometer Simulation A Micrometer is used to measure the external dimensions of objects that are 3 cm or smaller, this provides precise measurements to inside 0.01 mm. The
For a very every case the moment of inertia of a one particle about an axis is given by, I = mr 2 Here, m is the mass of the particle and r its distance from the axis under

With that purpose was famous Davisson-Germer experiment with electrons performed? Name the type of communication in which the sign is a discrete and binary coded version of the
When a plane is in flight, the entire weight of the aircraft is essentially supported by the wings. To help you with this problem, it will be best if you visualize holding a model
POSITIVE ACCELERATION: If velocity of a body is enhancing, then its acceleration is said to be positive. The direction of positive acceleration is similar as that of velocity.
