Q. A molecule in air is moving at a speed of 459 m/s. How various meters would the molecule move during 7ms if it didn't collide with any other molecules?
find the volume of the irregularly shaped object. What is sigma_inner, the surface charge density (charge per unit area) on the inner surface of the conducting shell.
A passenger train is travelling at 32 m/s when the engineer sees a freight train 384 m ahead of his train travelling in the same direction on the same track. The freight train is moving at a speed of 5.7 m/s.
A wave on a Slinky has a frequency of 1.69 Hz. It takes 4.1 s to travel the length of the Slinky (0.29 m). What is the wavelength.
At one instant, a mass (m = 2 kg) is at the location m and attached to one end of a spring with a spring constant ks = 60 N/m and a relaxed length L0 = 0.22 m. The origin is placed where the other end of the spring attaches to the ceiling.
illuminate the object with the flashlight. One way to produce artificial gravity in a space station is to spin it.
