Find the first three harmonics of a string of linear mass density 2.00 g/m and length 0.600 m when the tension in it is 50.0 N. 66 Hz, 132 Hz, 198 Hz 264 Hz, 528 Hz, 792 Hz 132 Hz, 264 Hz, 395 Hz none of the above Q

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

i think the answer is a and b

i wish you luck

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
