An electron travels in a straight line from the cathode of a vacuum tube to its anode, which is 1 cm away. Its initial and final speed is 0 and 6.0*10^6 m/s respectively.
(a) Assume the constant acceleration and compute the force.
(b)Compare it with gravitational force on the electron which we neglect when we assumed straight-line motion. Is this assumption valid?

The human body stores chemical energy from digested food. some of the chemical energy is converted into mechanical energy when the body moves. which statement best supported by this information

At very high pressures, gases become and will eventually a) more dense; become hotter b) more dense; change to a liquid or solid c) less dense; combust d) less dense; turn into a liquid

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.
