The figure shows a block of mass M hanging at rest. M is 12.5 kg. The light wire fastened to the wall is horizontal and has a tension of 38 N. The wire fastened to the ceiling is also very light, has a tension of 49 N and makes an angle θ with the ceiling. Find the angle θ, in degrees, and only enter the number.
Estimate how many patterns in AY are recognizable as the character ‘2'. [The aim of this problem is to try to demonstrate the existence of as many patterns as possible that are recognizable as 2s.]
1. If a wave traveling through air decreases its wavelength by half, describe what happens to the wave speed and frequency. 2. A transverse wave is traveling down a rope with mass, m = 10 kg, and length, L = 50 m. If the rope is under a tension for..
