a block of mass 5.62 kg lies on a frictionless horizontal surface. The block is connected by a cord passing over a pulley to another block of mass 2.53 kg which hangs in the air.
Calculate the Acceleration of the first block. The acceleration of gravity is 9.8 m/s square root of 2. Answer in units of m/s square root of 2.
Ultrasonic acoustic waves are diffracted by a pair of parallel slits 100mm apart. The zeros in the diffraction pattern are spaced at angular intervals of 8.3 degrees. Calculate the wavelength.
