A spring with spring constant k and length L has masses m attached at each end of the spring, and is placed on a frictionless table. Both masses are pulled x from equilibrium and released.1.What is the period of oscillation of the individual masses?2.What is the maximum potential energy stored in the spring?
The threshold of dark-adapted (scotopic) vision is 6.0 x 10-11W/m2 at a central wavelength of 500 nm. how many photons per second enter the eye
An object-spring system oscillates with an amplitude of 3.4 cm. If the spring constant is 210 N/m and object has a mass of 0.50 kg, obtain the maximum acceleration of the object
If a circuit has two resistors in a parallel series with resistances 4.0 kΩ and 2.0 kΩ and has two capacitors with capacities 3.0 μF and 6.0 μF and the capacitors begin to charge then what is the time constant for the charging process?
in general the quantization of transitional motion is insignificant for atoms because of their mass. however this
A rubber ball is dropped and bounces vertically from a horizontal concrete floor. If the ball has a speed of 3.2 m/s now before striking the floor and a speed of 2.1 m/s just after bouncing, what is the average force of the floor on the ball? Suppose..
A copper bar is moved to the right while its axis is maintained in a direction perpendicular to a magnetic field, what is the direction of the magnetic field
If it takes 3.60 x10-13 s for a nitrogen molecule to hit the wall and rebound with the same speed but moving in an opposite direction (assumed to be the negative direction), what is the average acceleration of the molecule for the period of this t..
The timekeeping of an old clock is regulated by a brass pendulum 20.0 cm long. If the clock is accurate at 20C but is in a room at 18 C, how long will it be before the clock is in error by one minute? Will it be too fast or too slow?
The bullet first passes through the left disk and then through the right disk. It is found that the angular displacement between the two bullet holes is θ = 0.320 rad. From these data, evaluate the speed of the bullet.
