thatnks for helping. ive tried this question all day, and its due tonight. here it is The force exerted on a 0.145 kg baseball by a bat changes from 0.0 N to 1.0 104 N over 0.0010 s, then drops back to zero in the same amount of time. The baseball was going toward the bat at 23 m/s...

hi, thanks for helping me. heres the question Suppose the moon had a net negative charge equal to -q and Earth had a net positive charge equal to +10q. What value of q would yield the same magnitude force that you now attribute to gravity? (answer in coulombs) I have it on a thing...

i really have no idea about any of these, they become way too confusing, i know that you can use frequency and wavelength to get speed, but that's about it

hey guys idk how you know all this stuff, and id appreciate if you helped me. i have to do wavelength and and frequency problems and i don't really understand how to do it the way my teacher taught it, so here they are and thanks for helping me. 1.The frequency of yellow light is 5.5 1014...
