Q1. The intensity of sunlight that reaches Jupiter (orbiting at about 5 AU) is approximately what fraction of that at Earths orbital distance?
Q2. A 3300 kg auto tows a 4500 kg horse trailer. If the engine causes the ground to push the car forward with 8.58kN:
a) what is the acceleration of the horse trailer?
b) What is the forward force on the trailer?
c) With how much force does the trailer pull back on the car?
A monochromatic beam of light is absorbed by a collection of ground-state hydrogen atoms in such a way that three different wave-lengths are observed while the hydrogen relaxes back to the ground state. What is the wavelength of the incident beam.
How do you establish the value of theta
How much time is necessary to catch the car
Compute magnitude of the average velocity
A 36.0 kg uniform beam is attached to a wall with the hinge while its far end is supported by a cable such that the beam is horizontal.
A 75 kg parachutist descends through a vertical height of 310 m with constant speed. Find the increase in entropy produced by the parachutist, assuming the air temperature is 21°C.
Clifford is in a real hurry, however, and skips the speed ramp. Starting from rest with an acceleration of 0.49 m/s2, he covers the same distance as the ramp does, but in one-fourth the time. What is the speed at which belt of the ramp is moving.
What is the speed of the projectile immediately before it hits the ground if air friction does one and a half times as much work on the projectile when it is going down as it did when it was going up.
What is EMF in the secondary circuit
A rifle with a barrel length of 56 cm fires a 14 g bullet with a horizontal speed of 350 m/s/s. The bullet strikes a block of wood and penetrates to a depth of 13 cm.
What is magnitude of the runners total displacement
A 0.65 percent C hypoeutctoid plain carbon steel is slowly cooled from about 950°C to a temperature just slightly above 723°C. calculate the weight percent austenite and weight percent proeutectoid ferrite in this steel. Explain it.
