A simple harmonic oscillator takes 12.0 s to undergo six complete vibrations.
determine the downward force of the rails on the car when the upside-down car is at the top of the loop
A stone with a mass of 0.900 kg is attached to one end of a string 0.900 m long. The string would break if its tension exceeds 60-N. The stone is whirled in a horizontal circle on a frictionless tabletop.
A sinusoidal wave travels along a stretched string. A particle on the string has a maximum velocity of 0.900m/s, What is the frequency and amplitude of the wave
A French submarine and a U.S. submarine move toward each other during maneuvers in motionless water in the North Atlantic, What are the speeds of the U.S. and the French subs
One ball is perfectly inelastic and stays on the wall after collision andsecond ball is elastic and bounces of the wall. Elucidate the momentum change
Elements that appear in the same column of the periodic table often share similar chemical properties. In the case of the alkaline earth metals, calculate the path radius of the Ca ion
It bounces off with the same speed and angle. If the ball is in contact with the wall for 0.220 s, elucidate what is the average force exerted on the ball by the wall?
A door of width 1.0 and height 2.0 weighs 279 and is supported by two hinges, one a distance 0.500 from the top and the other a distance 0.50 from the bottom. Each hinge supports half the total weight of the door.
On a summer day, the air conditioning breaks down and the air in your classroom becomes very warm and muggy with a vapour pressure of 20 hPa and a temperature of 25o C.
Two capacitors C1 = 3.2 ?F, C2 = 13.5 ?F are charged individually to V1 = 19.0 V, V2 = 5.6 V. Calculate the final potential difference across the plates of the capacitors once they are connected
A bicycle wheel has a diameter of 64.1 cm and a mass of 1.81 kg. suppose that the wheel is a hoop with all of the mass concentrated on the outside radius. The bicycle is placed on a stationary stand and a resistive force of 120 N is applied tangent..
