Arope with a mass density of 1 kg/m has one end tied to a vertical support. you hold the other end so that the rope is horizontal and has a tension of 4 n. if you move the end of the rope back and forth, you produce a transverse wave in the rope with a wave speed of 2 m/s. if you double the amount of tension you exert on the rope, what is the wave speed?

What is meant by the statement" the melting poin of glycerine is 13 degree celsius

There are two-speed cameras, one in an are where the speed limit is 30 km/h and another where the speed limit is 50 km/h. in which will there be a smaller time interval between the photographs? explain your answer.

An electron is trapped at a defect in a crystal. the defect may be modeled as a one-dimensional, rigid-walled box of width 1.00 nm. (a) sketch the wavefunctions and probability densities for the n 1 and n 2 states. (b) for the n 1 state, nd the probability of nding the electron between x1 0.15 nm and x2 0.35 nm, where x 0 is the left side of the box. (c) repeat (b) for the n 2 state. (d) calculate the energies in electron volts of the n 1 and n 2 states
