A sine or cosine wave is travelling in air. The difference between the minimum separation of any two particles on the wave always having the same speed and the same velocity i.e. separation of 2 particles with same speed - separation of 2 particles with same velocity is. O f/ Ολ O O2
A sine or cosine wave is travelling in air. The difference between the minimum separation of any two particles on the wave always having the same speed and the same velocity i.e. |separation of 2 particles with same speed - separation of 2 particles with same velocity|
1. A box (mass m = 20 kg) is placed on a slope (LaTeX: \thetaθ = 40°), as shown in the diagram below. The coefficients of friction between the box and the slope are LaTeX: \muμs = 0.6 and LaTeX: \muμk = 0.4. The box is released from rest on the slope. Determine the acceleration of the box after it is released. 2.A diving board has length of 1.8 m and a total mass of 65 kg. However, the mass...

U Question 4 2 pts Problem 3: Proton travelling inside a parallel-plate capacitor. A proton travelling at a speed of 1.0 x 106m/s enters the gap between the plates of a parallel-plate capacitor. The plates are 2.0 cm long in the direction the proton is travelling and the surface charge densities on the plates are 1.0 x 10C/m². Assume the electric field is uniform inside the capacitor and zero outside. The mass of a proton is 1.7 x 10-27 kg....
