Q. Imagine that the proton and electron in a hydrogen atom were not charged. They could still form an atom based on the gravitational (instead of electrostatic) attraction between the two quantons. What would be the minimum energy of the electron in this gravitational atom? What would be its minimum size.
Q. Assume BCA passes through a pulley at point C and supports a crate at point A. Rope segment CD supports the pulley and is attached to an eye anchor embedded in a wall. Rope segment BC creates an angle of = 75.0 with the floor and rope segment CD creates an angle with the horizontal. If both ropes BCA and CD can support a maximum tensile force = 575 , what is the maximum weight of the crate that the system can support? What is the angle required for equilibrium?
A calorimeter contains 2000 grams of water at 0oc. a jet of stream at 100oc is passed through the water. What is the temperature of the water when 100 grams of steam have condensed in it.
A beam of 6 MeV electrons passes through a 400 micro-meter thick silicon detector. Estimate the energy lost by the electrons when crossing 200 micro-meters, 300 micro-meters and the full thickness of the detector.
An airplane is flying with a velocity of 81.0 m/s at an angle of 24.0^circ above the horizontal. When the plane is a distance 108m directly above a dog that is standing on level ground, a suitcase drops out of the luggage compartment.
A 53 kg skier skis directly down a frictionless slope angled at 12° to horizontal. Choose the positive direction of the x axis to be downhill along the slope.
An unmarked police car, travelling a constant 94 km/h, is passed by the speeder travelling 153 km/h. precisely 0.70 s after the speeder passes, policeman steps on the accelerator. If the police car's acceleration is 2.30 m/s^2, how much time elapses ..
Suppose that a structure of arbitrary complexity has a number of forces applied to it (at various points) and yet is in static equilibrium. The principle of virtual work allows one to write an equation that relates the applied forces.
A projectile is launched at some speed at an angle of 74 degrees and travels a range of 262 meters. The launch angle is after that changed, but the projectile is fired at the same speed as the original case and also travels the same range of 272 m..
What is the magnitude of the force that maintains circular motion acting on puck.
A large cylindrical water tank is mounted on a platform with its central axis vertical. The water level is 3.75 m above the base of the tank, and base is 6.50 m above the ground. A small hole 2.23 mm in diameter has formed in the base of the tank. Bo..
A 220 g block is attached to a horizontal spring and executes simple harmonic motion with a period of 0.150 s. If the total energy of the system is 3.50 J.
