Q. A person with perfect pitch sits on a bus bench listening to the 445 Hz horn of an approaching car. If the person detects a frequency of 488 Hz, how fast is the car moving?
Q. When an ideal gas expands adiabatically, it does work on its surroundings. Describe the various transfers of energy that take place.
What is an average number of ozone molecule
If a car traveling at 55 km/h will skid 24 m while its brakes lock, how far will it skid if it is traveling at 130 km/h when its brakes lock.
Block 1, of mass m_1 = 0.500 kg, is connected over an ideal (massless and frictionless) pulley to block 2, of mass m_2. Suppose that the blocks accelerate with an acceleration of magnitude a = 0.550 m/s^2 and that coefficient of kinetic friction b..

A solid cylinder of radius 0.35 m is released from rest from a height of 1.8 m & rolls down the incline as shown. Find the angular speed of the cylinder when it reaches the horizontal surface?
A 100 arrow is shot perpendicularly from a bow whose effective spring constant is 500. If the bow is drawn 75 before shooting the arrow, to what height does arrow rise.
A 2kg lunchbox is sent sliding over a frictionless surface, in positive direction of an x axis along the surface. Start at time t = 0, steady wind pushes on the lunchbox in the negative direction of the x axis.
After a tornado, a 0.55-g straw was found embedded 2.8 cm into the trunk of a tree. If the average force exerted on the straw by the tree was 70 N, what was speed of the straw when it hit the tree .
