Afire hose must be able to shoot a stream of water a specified height, straight up. calculate the gauge pressure (difference between actual pressure and atmospheric pressure) required in the water main supplying the hose. assume that the diameter of the main is sufficiently larger than that of the hose that the velocity of the water in the main is negligible.

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

Determine the fraction of the magnitude of kinetic energy lost by a neutron (m1 = 1.01 u) when it collides head-on and elastically with a target particle at rest which is 21h (heavy hydrogen, m = 2.01 u).

What properties of a moving object are used in determining the object's energy of motion
