You apply a 100N force to a 20kg block. It doesn't move. Why? What is the mass? Draw a free body diagram.

The largest salami in the world, made in Norway, was more than 20 m long. If a hungry mouse ran around the salami's circumference with a tangential speed of 0.17 m/s, the centripetal acceleration of the mouse was 0.29 m/s2.

Which fault will see the hanging wall move down relative to the footwall?

A block oscillating on a spring has period t = 3.0 s. note: you do not know values for either m or k. do not assume any particular values for them. the required analysis involves thinking about ratios.

Predict whether the changes in enthalpy, entropy, and free energy will be positive or negative for the melting of ice, and explain your predictions. How does temperature affect the spontaneity of this process?
