Q. A 3 kg block is observed to accelerate at a rate twice that of the 6 kg block. Is the net force acting on the 3 kg block therefore twice as large as that performing on the 6 kg block? Explain.
Q. A force vector has a magnitude of 594 newtons and points at an angle 41o of below the positive x axis. What is (a) x scalar component and (b) y scalar component of the vector?
A certain type of laser emits light that has a frequency of 5.4 x10^14 Hz. The light, so, occurs as a series of short pulses, each lasting for a time of 2.7 x10-11 s.
