What is the difference between two consecutive nodes?
What is the difference between two consecutive nodes? Hence we can say that the phase difference between the particles vibrating between two consecutive nodes is zero. What is the least distance between two consecutive nodes? In a stationary wave, the distance between two successive nodes(anti-nodes) is one half wavelength. Therefore, the distance between a node […]
What are 3 types of kinetic friction?
What are 3 types of kinetic friction? Summary Friction is the force that opposes motion between any surfaces that are in contact. There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces. Fluid friction occurs in fluids, which are liquids or gases. What causes […]
