Please help! I got that the tension of a string on a yo-yo is 7.9 but what is the speed when the tension in the string is doubled?

if you already have the answer to (a), then just work out how many periods there are in 1 minute, and that's the answer to (c).

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.
