In a tungsten atom, what is the kinetic energy of an L-shell electron ejected by a photon that was created during the M-K shell transition of the atom?
After the first spring compresses a distance of 32.1 cm, the second spring acts with the first to increase the force as additional compression occurs. The car comes to rest 47.0 cm after first contacting the two-spring system. Find the car's initi..
A rifle with a barrel length of 62 cm fires a 12 g bullet with a horizontal speed of 460 m/s/s. The bullet strikes a block of wood and penetrates to a depth of 15 cm.
A 4.20 kg model rocket is launched, expelling 57.0 g of burned fuel from its exhaust at a speed of 675 m/s. What is the velocity of the rocket after fuel has burned.
Beats of frequency 4Hz are heard when a tuning fork of frequency 1000Hz and a vibrating wire are sounded together. What is frequency of the wire.
A 60.0-kg skater begins a spin with an angular speed of 6.0 rad/s. By changing the position of her arms, the skater decreases her moment of inertia by 50%. Find the skater's final angular speed?
A 2 kg object is attached to a spring and placed on a horizontal, smooth surface. A horizontal force of 20.0 N is needed to hold the object at rest when it is pulled 0.200 m from its equilibrium position.
A 38 g bullet is fired with a speed of 180 m/s into a 5 kg sandbag pendulum that is free to swing. To what maximum vertical height will the pendulum rise.
A 51.0-g Super Ball traveling at 27.0 m/s bounces off a brick wall and rebounds at 21.5 m/s. A high-speed camera records this event. If the ball is in contact with the wall for 3.75 ms,
Two steel guitar strings have the same length. String A has a diameter of 0.59 mm and is under 450.0 N of tension. String B has a diameter of 1.2 mm and is under a tension of 800.0 N. Find the ratio of the wave speeds, va/vb, in these two strings.
Obtain an expression for the velocity
How many revolutions per minute would a 29 {rm m}-diameter Ferris wheel require to make for the passengers to feel "weightless" at topmost point.
(1) A circular wheel has a radius R = 0.45 + or - 0.02 m. The wheel is observed to be rotating uniformly with period T = 2.00 +or- 0.05 s. (i) Compute the frequency with which the wheel spins (ii) Compute the angular speed of the wheel. (iii) Comp..
