That's a longitudinal wave, and a compressional wave.

Waves generated are called longitudinal waves cuz displacement of the medium is in the same direction as, or the opposite direction to, the direction of travel of the wave. Longitudinal waves are also called compression waves. Hope it helps

What is the IMA of a two-gear system if the resistance gear has 54 teeth and the effort

Dafna1 [17]

Answer:

IMA = 2

Explanation:

Given the following data;

Resistance gear = 54 teeth

Effort gear = 23 teeth

To find the ideal mechanical advantage (IMA);

IMA = number of teeth on the resistance gear/number of teeth on the effort gear

Substituting into the equation, we have;

IMA = 54/23

IMA = 2.35 ≈ 2

Therefore, the ideal mechanical advantage (IMA) of this two-gear system is 2.

A light bulb emitting 1750 Im of luminous flux shines on a book that is 3.0

denis-greek [22]

The illumination of the book is found to be approximately equal to 15 lx.

Option 1.

Explanation:

Luminous flux is the measure of power of the light emitted from a source and illumination is the property of the light to illuminate a given surface when it falls on the surface. So the measure of the region the light flux illuminates the surface is termed as illumination.

As here the luminous flux is given as 1759 lm and the distance of the object which has to be illuminated is placed 3 m away from the source ,the illumination is found to be directly proportional to the luminous flux and inversely proportional to the square of the distance between them

$illumination = \frac{Luminous flux}{4\pi d^{2} } \\\\illumination = \frac{1750}{4*3.14*3*3} = 15.48 lx = 15 lx$

So, the illumination of the book is found to be approximately equal to 15 lx.
