1. What is the Schwarzschild radius of a black hole that has a mass eight times that of our Sun? Note that stars must be more massive than the Sun to form black holes as a result of a supernova.
2. Black holes with masses smaller than those formed in supernovas may have been created in the Big Bang. Calculate the radius of one that has a mass equal to the Earth's.
A system has a heat source supplying heat at a rate of 187 W and is doing work at a rate of 130.899998 W. At what rate is the internal energy of the system changing.
A ball with 3gr mass and momentum P strikes elastically a wall and bounces off. Calculate the change in the ball's momentum
Consider a simple pendulum with L = 2.4 m and m = 1.8 kg. Suppose the mass is initially at rest at the lowest point on its trajectory when it is given an impulse such that it then has a velocity of 0.17 m/s. What is the total mechanical energy of the..
A stone is thrown from the top of a cliff that is 34.6 m high at a velocity of 13 m/s 230 above the horizontal. How long does it take to hit the ground below the cliff
Suppose you do 457 J of work on 1.18 moles of ideal gas in a perfectly insulated container. By how much does the internal energy of this gas change.
The mass of the moon is 7.36 × 1022 kg and its distance to the Earth is 3.84×108m. What is the gravitational force of the moon on the earth
A 9kg object is suspended from the ceiling by a strong spring, which then undergoes simple harmonic motion with a period of 0.4s. The block is brought to rest, and the equilibrium length of the spring with the block attached is measured. By how mu..
Using two optical elements which may be two lenses, one lens and one mirror, or two mirrors, invent an optical system that creates an erect image of a candle on a wall that s 10 times its actual height. Show your ray tracings and be sure to indicate..
A rod slides along a metal frame. The earth's magnetic field is 3.5× 10-5 T at right angles to the plane of the frame. Find the magnitude of the force on the rod
A mass is oscillating with amplitude A at the end of a spring. How far (in terms of A) is this mass from the equilibrium position of the spring when the elastic potential energy equals a third the kinetic energy?
Illustrate what are the velocities of the two people after the snowball is exchanged? Disregard the friction between the skates and the ice.
calculate the fraction of energy lost in the resistor in the charging RC circuit. By integrating the power dissipated in the resistor and applying energy conservation between t=0 and t= infinity.
