A 5.63 kg crate slides on a horizontal surface. The coefficient of kinetic friction between the surface and the crate is 0.383. estimate the magnitude of the external force acting on the crate
Physicians use electroencephalograms (EEGs) to study electrical oscillations in the human brain. So-called beta oscillations, whose enhancement has been linked to alcoholism, have frequencies from 12 to 30 Hz . What's the corresponding range in perio..

0.10 mol of argon gas is admitted to an evacuated 50 cm3 container at 20° C. The gas then undergoes isobaric heating to a temperature of 300° C. What is the final pressure of the gas? What is the final volume?
A planet orbits a star, in a year of length 2.49 x 107 s, in a nearly circular orbit of radius 2.39 x 1011 m. With respect to the star, evaluate the angular speed of the planet
a 10-kg block is dragged up a 30deg rough ramp by an applied force f. the coefficients of static and kinetic friction
The 1 kg block is tied to the wall with a rope. It sits on top of the 2 kg block. The lower block is pulled to the right with a tension force of 20 N. The coefficient of kinetic friction at both the lower and upper surfaces of the 2kg block is = 0..
The speed of an alpha particle is determined to be 8.75×106 m/s. If all of its kinetic energy is acquired by passing through an electric potential, what is the magnitude of that potential
