A non-uniform flask consists of a lower portion that is a circular cylinder 20 cm in radius and 20 cm high. The upper portion is also a circular cylinder, which is 2 cm in radius and 40 cm high. The flask is filled with water. Calculate:
A. The total weight of the water in the flask
B. The gauge pressure of the water at the bottom of the flask
C. The force exerted on the base of the flask due to the gauge pressure
A uniform solid disk with a mass of 23.8 kg and a radius of 0.712 m is free to rotate about a frictionless axle. Forces of 92.0 and 124 N are applied to the disk. Taking the clockwise direction to be the negative direction, what is (a) net torque pro..
Treating a lightning bolt as a long, thin wire, calculate the magnitude of the magnetic field produced by such a bolt of lightning at a distance of 71 m.
Find out the frequency of a sound wave moving through iron at 25 degrees Celsius with a wavelength of 0.601m.
The bullet passes right through and emerges on the other side with a speed of 100 m/s, and the saxophone is given a speed of 4.8 m/s.
