Q. An unstable nucleus with a mass of 17.0 E-27 kg initially at rest disintegrates into three particles. One of the particles, of mass 5.0 E-27 kg, moves along the positive y-axis with a speed of 6.0 E 6 m/s. Another particle, of mass 8.4 E-27 kg, moves along the positive x-axis with a speed of 4.0 E 6 m/s. (Assume that mass is conserved.)
Determine the third particle's speed and direction of motion.
What is the angular momentum of a 3.2 kg uniform cylindrical grinding wheel of radius 12cm while rotating at 1400 rpm.
Two 18 cm diameter charged disks face each other, 25 cm apart. Both disks are charged to - 30 nC. What is the electric field strength at the midpoint between two disks.
An "energy bar" contains 21g of carbohydrates. If the energy bar was his only fuel, how far could a 68 kg person walk at 5km/hr? Express your answer using two significant figures.
A 346-, uniform, 1.04- bar is suspended horizontally by two vertical cables at each end. Cable A can support a maximum tension of 506.0 without breaking, and cable B can support up to 436.0. You want to place a small weight on this bar. What is the h..
