Two forces p and q act on an object of mass 11.0 kg with q being the larger of the two forces. when both forces are directed to the left, the magnitude of the acceleration of the object is 0.900 m/s2. however, when the force p is directed to the left and the force q is directed to the right, the object has an acceleration of 0.400 m/s2 to the right. find the magnitudes of the two forces p and q .

Hydrogen atoms are excited by a laser to the =4n=4 state and then allowed to emit. what is the maximum number of distinct emission spectral lines (lines of different wavelengths) that can be observed from this system? 8 6 2 7 4 5 1 3 calculate the wavelength of the 4⟶14⟶1 transition. =λ=

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.

The solid that is formed and usually sinks to the bottom of a solution is the
