Which statements describe velocity and acceleration? Check all that apply. Velocity equals displacement divided by time. All velocities are “instantaneous” and occur only at a point in time. Velocity and acceleration are calculated using the same variables. Acceleration equals change in velocity divided by time. Acceleration is always constant; it cannot vary. Average velocity can be found by using several velocities and their total time.

Calculate the heat capacity per object when the total energy is 4 quanta. (think of this in terms of increasing from 3.5 quanta of energy in the system to 4.5 quanta of energy in the system, if that were possible.) c4 = __ j/k/object

An object has a weight of 500 on earth what is the mass of this object

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
