Assume air resistance is negligible unless otherwise stated. Calculate the displacement and velocity (in m and m/s, respectively) at the following times for a ball thrown straight up with an initial velocity of 20.5 m/s. Take the point of release to be y0= 0

Aball bearing at 220.0 °c is dropped into a cup containing 250.0 g of water at 20.0 °c. the water and ball bearing come to a temperature of 30.0 °c. what is the heat capacity of the ball bearing in j/°c? (hint: how are the algebraic signs of q related for the ball bearing and the water? )

What would be the result of an alpha particle coming into a magnetic field? a) the alpha particle will stop moving. b) the alpha particle will reverse its direction. c) the alpha particle will be deflected in a curve path. d) the alpha particle will continue to travel in a straight line.

When using the scientist method, which step comes last?
