At particle colliders, subatomic particles of relatively low mass are accelerated to very nearly the speed of light, so that their combined energy when smashed together head-on is sufficient to produce more exotic particles of much greater mass.
Suppose you could do this sort of thing on a macroscopic scale. How fast would you have to smash two 1 kg chickens together to make a 400 kg cow? Express your answer as a result for 1 - β.
Doppler speed meter operating at exactly 1.02 x 10^5 Hz emits sound waves in the direction of anoncoming baseball. The meter detects the reflected sound waves and measures a beat frequency of .30X10
A car with a mass of 980 kg is initially traveling east toward an intersection with a speed of vc = 20.8 m/s, Determine the initial speed of the truck and the final speed of the wreckage
an object is placed a distance r in front of a wall where r exactly equals the radius of curvature of a certain concave
The Doppler effect can be used to measure flow rates in blood. A sound wave is transmitted into a vein or an artery, What is the expected frequency shift
A ball is thrown vertically upward with a speed of 19.6 m/s, what is the ball's velocity after 1.0 sec? 3.0 sec?
a block of mass 0.222 kg is placed on the end of a spring which has a stiffness of 150. nm. it is pulled down 2.60 cm
Two balls of equal mass collide and travel off in different directions as shown. Assume the red (inicident) ball leaves at an angle of 60ofrom it's initial direction of motion and the green (originally stationary) ball leaves at an angle of 30o. (Not..
A child leaves her book bag on a slide. The bag, which is at the top of the slide, starts from rest and reaches the bottom in 1.40 s. What is the friction force acting on the bag
During a demonstration in our classroom, I hold a big magnet right under the big table pointing North Pole up. what is the induced emf in the loop
Two cylindrical glass beads each of mass m = 32 mg are set on their flat ends on a horizontal insulating surface separated by a distance d = 3 cm. The coefficient of static friction between the beads and the surface is μs = 0.3.
What is the spring stiffness of the entire wire, considered as a single macroscopic (large scale), very stiff spring?
