Question

Type the correct answer in the box. Use numerals instead of words.

The mechanical advantage shown in the image is
.

Answer 1

Step-by-step explanation:

Two EM waves of nearly same (600 nm) wavelength are measured on a spectrum analyzer to have a frequency difference of 0.1 GHz. While travelling through a dispersive medium, an interferometer is used to measure their wavelength difference of 0.001 nm. What is the group velocity of the wave combination in that medium

Answer 2

Step-by-step explanation:

Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system.

now here we can say that mechanical advantage is given as

MA = \frac{output \: force}{input \: force}MA=

input force output force

here we know that

output force = 156 N

input force = 52 N

so we will have

MA = \frac{156}{52}MA= 51156

MA = 3MA=3

so here mechanical advantage is 3
