A cosmic ray interacts for a mere 11fs with its detector. Having just learned about the uncertainty principle, you realize that this interaction time establishes a precision limit on measurement of cosmic-ray energy.
A. Find the minimum uncertainty in that energy.
B. Find the fractional uncertainty for a 4.5 MeV cosmic ray. (?E/E=?)
A rock is thrown downward into a well that is 8.90 deep. If the splash is heard 1.20 seconds later, what was the initial speed of the rock? Take the speed of sound in the air to be 343 m/s.
How much work must be done on the electron to move it to negative plate if it is initially positioned 2.86 mm from the positive plate.
An electron moves at a speed of 14000 m/s in a circular path of radius 2.4 cm in a solenoid. Find the strength of the magnetic field inside the solenoid
Suppose that the mass of the dishwater is large as much as necessary so that its temperature does not change appreciably.
A lead ball is dropped into a lake from the diving board 30 m above the water. After entering the water, it sinks to the bottom with the constant velocity equal to velocity with which it hit the water. The ball reaches the bottom 10 s after it is ..
Given a metal which has a coefficient of volume expansion given by B(T) = 8.0x10^-6 K^-1 + (1.2x10^-8 K^-2)T caluclate the work done by this is obaric process
What percentage of error in would be made if the moment of inertia of the pulley were avoid? Ignore friction in the pulley bearings.
A bicycle wheel of radius 0.4 m is spinning at a rate of 65 revolutions per minute. find the centripetal acceleration of a point on the edge of the wheel
There is a uniform electric field on both sides of a large plane. Its magnitude is 80 N/C and its direction is toward the plane, on each side of it
Charge is scattered uniformly throughout a long cylindrical shell of inner radius R and out radius 2R. At what radius is the electric field equal to one-half the value on the outer surface.
Water is in the big beaker. Scale 1 reads 87 newtons, scale 2 reads 948 newtons, and scale 3 reads 0 newtons. The hanging block has a density of 10 × 10^3 kg/m3. To the nearest tenth of newton what does scale 1 read after the block is fully lowere..
A fuel leak is discovered at this point, and crew calculates that the plane can safely fly no more than 170 km before an emergency landing should be attempted. The only appropriate location for an emergency landing is 100 km north of their current po..
