A stone is thrown downward with a speed of 7.1 m/s. If the stone reaches the ground in 7.27 seconds, determine the height from which it was thrown.

Determine the change in width a, height b, thickness t when a plate is subjected to the uniform distributed load and is made of material having modulus of elasticity e=230 gpa and poisson's ratio ν=1/3. given : a=400 mm and b= 300 mm also the uniformly distributed load in downward y direction of plate is 2 mn/m and in the positive x direction is 3 mn/m and t=20 mm

In science and physics what is the standard unit of measure for speed?

The least penetrating form of radiation is
