please help. i need to solve IMA, EFFORT FORCE, and TENSION FORCE OF THE ROPE ATTACHED TO THE CEILING. thank you

What is the length x of the side of the triangle below? (hint: use the cosine function)

What is the electric force acting between two charges of -0.0045 c and -0.0025 c that are 0.0060 m apart? use fe=kq1q2/r^2 and k = 9.00 x 10^9 n*m^2/c^2 a. 1.7 x 10^7 n b. -1.7 x 10^7 n c. -2.8 x 10^9 n d. 2.8 x 10^9 n

Aparticle moves in a circle 1.50 m in radius . through what angle in radians does it rotate if it moves through an arc length of 2.50m? what is the angle in degrees?
