Answer:
The speed of light in air is c = 3 × 108 m/s.
Thus, the speed of light in glass will be given as.
v = c/n = 3 × 108/ 1.5 = 2 × 108 m/s.
The speed, wavelength and frequency are related as.
c = νλ
Thus, wavelength in air is given as.
λa = c/ν = 3 × 108/ 6 × 1014 = 5 × 10-7 m.
Answer:
Control valves are used in many processes to control flow, pressure, temperature or other variables. The type of valve used will depend on the size of the pipe, the overall pressure that the system operates, the flowing media, process conditions, and other factors.
Also
A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. This enables the direct control of flow rate and the consequential control of process quantities such as pressure, temperature, and liquid level.

Answer:
330Ns
Explanation:
Given parameters:
Mass of the box = 5kg
Initial velocity = 0m/s
Force applied = 15N
Time = 22s
Unknown:
Impulse = ?
Final momentum = ?
Solution:
The impulse of the box can be determined using the expression below:
Impulse = Force x time
Impulse = 15 x 22 = 330Ns
The final momentum is the same as this impulse
The impulse and the final momentum is 330Ns
