Hii could someone answer these for me please. thank you so much for your time.

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

The law of the conservation of momentum says that the total momentum of any closed and isolated system cannot

Acoil suspended freely, points in some direction when no current is passed through it . can you tell what will happen when a current is passed though it?
