Arotating star, with a velocity at its equator of 600 km/s. calculate the difference in the wavelength of light (emitted with a wavelength of 550 nm, or yellow light) emitted from receding edge of the star on its equator against the wavelength of light (550 nm) observed from the approaching edge of star? i believe it has something to do with these equations, just am confused about how to calculate these. it relates to the doppler effect i am sure, and the shift of light (from our sun for example) being shifted in frequency/wavelngth by the rotational motion of the earth.

What type of relationship exists between the length of a wire and the resistance, if all other factors remain the same? o a. resistance is directly related to length. ob. resistance is directly related to the square of the length. c. resistance is inversely related to the length. d. resistance is inversely related to the square of the length. reset next

Argon, neon, and xenon are examples of

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.
