Using the force table, components of a vector can be found experimentally by suspending masses from two orthogonal strings which oppose the mass and string representing the vector in question. if 155 g is suspended at 210 degrees , what masses must be suspended at 0 degrees and 90 degrees to balance this force? (a) 182 g at zero, 105 g at 90 (b) 105 g at zero, 105 g at 90 (c) 121 g at zero, 70 g at 90

The metric unit of electrical power is the watt volt ampere ohm
