Explanation:
A solid state laser contains a cavity like structure fitted with spherical mirrors or plane mirrors at the end filled with a rigidly bonded crystal. It uses solid as the medium. It uses glass or crystalline materials.
It is known that active medium used for this type of laser is a solid material. This lasers are pumped optically by means of a light source which is used as a source of energy for the laser. The solid materials gets excited by absorbing energy in the form of light from the light source. Here the pumping source is light energy.
Answer: Solid state welding
Explanation: Solid state welding is the welding procedure which is based on the temperatures and pressure but without any liquid or vapor as aid for welding.This process is carried mainly cohesive forces and considering forces as less important. Brazing,soldering and adhesive is the process in which material are joint which the help of solid welding agent.Thus solid state welding is the correct option.
Answer:
True
Explanation:
By definition of steady flow we have
where f(x,y,z,t) is any property of the system under consideration
=> f(x,y,z,t) = constant
Answer:
the car to the right
Explanation:
its in the name the RIGHT of way hope it helps good luck
Viscosity isT=u(U/y) where T is shear stress & u is velocity and y is thr length
The answer is =2.57
