A wave on a string is described by D (x comma t )space equals space 2.0 space c m space sin (straight pi (12.57 straight x minus 638 straight t ))spacewhere x is in m and t is in s. The linear density of the string is 5.00 g/m. (a) What is the time period of oscillation of a point on the string in seconds

Asheet of steel 1.5 mm thick has nitrogen atmospheres on both sides at 1200oc and is permitted to achieve a steady-state diffusion condition. the diffusion coefficient for nitrogen in steel at this temperature is 6 x 10- 11 m2 /s, and the diffusion flux is found to be 1.2 x 10-7 kg/m2 -s. also, it is known that the concentration of nitrogen in the steel at the high-pressure surface is 4 kg/m3 . how far into the sheet from this high-pressure side will the concentration be 2.0 kg/m3 ? assume a linear concentration profile.

As a pendulum moves closer to the equilibrium position, how do the velocity, acceleration, and force change? the velocity decreases, the acceleration decreases, and the net force decreases. the velocity increases, the acceleration decreases, and the net force decreases. the velocity increases, the acceleration increases, and the net force decreases. the velocity decreases, the acceleration increases, and the net force increases.

Which evidence is lost likely used to indicate the beginning of solar system formation?
