Q. The volume of an ideal gas is increased from 1 m3 to 8 m3 while maintaining a constant pressure of 1000 Pa (1 Pa = 1 N/m2).
How much work is done by the gas in this expansion?
Q. A block is given an initial velocity of 5.00 m/s up a frictionless 20.0° incline. How far up the incline does the block slide before coming (momentarily) to rest?
Consider an angular motion. If the displacement is given as 250teθ, and the radius r is constant, derive the expressions for the angular velocity θ=ω, angular accelerationα, linear displacements, linear velocitytv, normal accelerationna, and tange..
A student yells across a street at a concrete wall. The student hears an echo 0.500 seconds later. If the speed of sound in air is 343 m/s, what is distance from the student to the wall only.
What is speed of the resulting ball of clay
A battery having an emf of 11.10 V delivers 102 mA when connected to a 61.0 load. Find out the internal resistance of the battery.
A loudspeaker of mass 21.0 {rm kg} is suspended the distance of h = 2.40 {rm m} below the ceiling by two cables that make equal angles with the ceiling. Each cable has a length of l = 3.90 {rm m}.
A 43kg block of ice slides down the frictionless incline 1.50m long and 0.82m high. A worker pushes up against the ice, parallel to the incline, so that the block slides down at constant speed.
