Titanium metal requires a photon with a minimum energy of 6.94×10^−19j to emit electrons.
(a)-what is the minimum frequency of light necessary to emit electrons from titanium via the photoelectric effect? express your answer using three significant figures.
(b)- what is the wavelength of this light? express your answer using three significant figures.

Two technicians are discussing a resistance measurement between the can-h and can-l wires. technician a says this measurement should be done with the ignition switch in the "run" position. technician b states that a measurement of 0 ohms indicates an open in the network. which technician is correct?

How would a small bar magnet be oriented when placed at position x?

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.
