Q1. The drawing shows the rectangular block of glass (n = 1.52) surrounded by a liquid with n = 1.630. A ray of light is incident on the glass at point A with a 30° angle of incidence. At what angle does the ray leave glass at point B?
Q2. An ideal heat-engine is to be used in an environment where the ambient temperature is 22.50 °C. What must be the minimum temperature of the hot heat reservoir in order to reach at least 46.40 percent efficiency with heat-engine? (Give the answer in Celsius.)
Each speaker produces a tone with a frequency of 200 Hz on a day when the speed of sound is 330 m/s. The person is 1.65 m from one speaker and 4.95 m from the other. What sort of interference does the person sense.
A 21.5 g bullet strikes a 0.650 kg block attached to a fixed horizontal spring whose spring stiffness constant is 7.30 x 10^3 N/m and sets it into vibration with an amplitude of 21.5 cm. What was the speed of bullet before impact if the bullet and bl..
In the meantime, the velocity of airplane Q relative to the air is 250 m/s in the direction of N 20o W. What is the speed of airplane Q relative to the airplane P.
A block of weight W can slide on a horizontal surface. A force of W/n1 is applied to the right that causes the block to accelerate with acceleration equal to g/n2. g is the acceleration by reason of gravity. If the coefficient of kinetic friction is ..
Two carts have a compressed spring between them and are initially at rest. One of the carts has total mass, including its contents, of 7.0 kg, and the other has total mass of 5.0 kg. If the 5.0 kg cart is moving at 3.0 m/s after the spring is allowed..
A 40 g rifle bullet travelling 260 m/s buries itself in a 4.0 kg pendulum hanging on a 3.0 m long string, which makes the pendulum swing upward in an arc. Find out the vertical and horizontal components of pendulum's displacement.
An artillery shell is fired with the initial velocity of 300 m/s at 54.7° above the horizontal. To clear an avalanche, it explodes on the mountainside 55.0 s after firing. What is the x and y components of the shell where it explodes, relative to its..
An object with a mass of 72.0 g displaces 590.0 ml of water when it is completely immersed. What is the buoyant force on the mass?
At its Ames Research Center, NASA uses its large "20-G" centrifuge to test the effects of very large accelerations ("hyper gravity") on test pilots and astronauts. In this device, an arm 8.84 {rm m} long rotates about one end in a horizontal plane..
A fire in an enclosure has reached flashover, & the gas temperature is assumed to be uniform at 1000oC. The enclosure has an opening 3 m wide & 2 m high. Find the position of the neutral layer, measured from the bottom of the opening.
What fraction of the power radiated by the sun is intercepted by the planet Mercury? The radius of Mercury is 2.44 x 106 m, and its distance from the sun at the moment is 5.75 x 1010 m. presume that sun radiates uniformly in all directions.
Discuss briefly centripetal acceleration, the speed and the force exerted by a ball attached to a string.
