Physics- Circular Motion
If you're only given the radius of a circle, how do you find the centripetal force? The hint is what is the centripetal acceleration at the top of the circle? You cant, unless you know something about the velocity. If the velocity is just sufficent to keep the mass in a ve...

Physics Again
How do you calculate the coefficient of friction, if it is not given to you? What would the formula be? It is a measured value. Force friction= mu*normal force. That is the usual method of solving for mu.

Physics
A spring is compressed .02m by a 0.5kg rock. The spring and rock are on a frictionless horizontal table. a) If the spring has a spring constant of 5N/m what acceleration will the rock have when released? b) How fast will the rock be moving when it reached the equilibrium point...

Physical change is simply the change from one state to another without change of composition such as the wax melting from a solid to liquid form and resolidifying.Chemical change is a change at the elemental level. In this case, you have both the wax and the wick burning. The ...
