... Describe how the Scottish physicist James Clerk Maxwell used Ampere’s law and Faraday’s law to predict the existence of electromagnetic waves and predict that light was just such a wave. Also understand that these predictions were confirmed by Heinrich Hertz, whose confirmations thus made possible t ...

... 3.2. Hockey puck #1 moving at 20 m/s makes an off-center elastic collision with an identical hockey puck, #2, that is at rest on horizontal, frictionless ice. Puck #1 is deflected at an angle of 20˚ from its original direction of motion. Find the velocity of pucks #1 and #2 after the collision, incl ...

Newton`s Laws Review
... A 1.167 kg block of wood is initially at rest at the top of a ramp that makes an angle of 43.1 o from the horizontal. If the coefficient of sliding friction is 0.282, what will be the acceleration of the block as it slides down the ramp? ...
