A muscle builder holds the ends of a massless rope. At the center of the rope, a ball is hung as shown. The tension force in the rope is T = 100N. What is the mass of the ball if the angle in the drawing is 15.0 degrees?
Covers the distance in the same time as car A. (a) Is car B"s final velocity smaller than, equal to, or greater than car A"s constant velocity?
A projectile is fired horizontally from a gun that is 44.0 m above flat ground, emerging from the gun with a speed of 370 m/s. (a) How long does the projectile remain in the air? (b) At what horizontal distance from the firing point does it strike
A stone thrown upward from the top of a 100 ft cliff at 150 ft/s eventually falls to the beach below. (For this problem take the acceleration due to gravity to be -32 ft/s^2 ; take upwards to be a positive direction.) How long does it take the sto
Assuming that the average gauge pressure in the artery is 13.3 kPa and the density of the electrolyte solution is 1030 kg/m3, what is the minimum height h in order for the infusion to work?
When identical amounts of heat are supplied to each, the glass bar reaches a temperature of 96 °C, while the other bar reaches 257.0 °C. What is the specific heat capacity of the other substance?
You are most sensitive to waves of this frequency, because your ear canal actually resonates with the sound, what"s the NEXT harmonic that"s allowed?
Calculate the emf that could be induced in a loop around the outside of the tongue by this motion of the head. (A typical tongue area is 25 times 10^-4 m^2.
Explain how a sound is actually a form of energy? In what medium do sound waves travel?
In a television, electrons shoot down the picture tube and strike fluorescent material on the screen, causing light to be emitted and producing the picture. Suppose that a certain set, the electrons are accelerated from rest 2.0 x 10^8 ms-1 in abo
