Suppose that you hear a clap of thunder 16.2s after seeing theassociated lightning stroke. The speed of sound waves in air is343m/s and the speed of light in air is 3.00* 10^8m/s. How far are you from the lightning stroke?
The intensity of radiation from a distant source like the Sunvaries inversely with the square of the distance from thesource. At the top of Earth's atmosphere the solar intensity(power per unit area) is 1.35 kW/m2.
One radiator has a volume of 0.09mt³. It contains saturated vapor at a temperature of 100°C. find The total mass of vapor in the radiator
An alternating source drives a series RLC circuit with an emf amplitude of 6.07 V, at a phase angle of +33.3°. what is the potential difference across the inductor
A particle p traveling with a speed of vpi = 3 m/s hits and scatters elastically from another particle N, initially at rest. Particle p is deflected through 90°, leaving with a speed of vpf = 2.7 m/s, and a mass mp = 2 kg. What is the speed of the..
A uniform narrow tube 1.70 long is open at both ends. It resonates at two successive harmonics of frequencies 245 and 294. What is the speed of sound in the gas in the tube
