A type of pinball machine uses a spinning rubber disk to deflect the ball. Suppose this disk has a radius of 6.50 cm, and the disk is horizontal so that gravity does not also affect the ball’s motion. Calculate the magnitude of the ball’s centripetal acceleration when the ball has a tangential speed of 1.95 m/s at the outer edge of the disk.. Single line text.

What are similarities and differences of reflection, refraction, diffraction and absorption?

Determine the change in width a, height b, thickness t when a plate is subjected to the uniform distributed load and is made of material having modulus of elasticity e=230 gpa and poisson's ratio ν=1/3. given : a=400 mm and b= 300 mm also the uniformly distributed load in downward y direction of plate is 2 mn/m and in the positive x direction is 3 mn/m and t=20 mm
