i didn't get u by figuring time by using velocity of sound. What is the velocity of sound.
SO what is the force for the second question..
Sorry for writing the incomplete question. But yeah..it is how much power do your 30, 60, 90 watt light bubls use when connected to icelandic electrical sockets?
hey Mr. Bob I was just wondering why did u take the charge of nucleus +e instead of 3e which is unclear to me..also we gotto find the total force on valence electron ie from both nucleus and the two electrons..am i correct....if not can u help me out..
