Answer:

<em>D. refraction</em>

Explanation:

Refraction: Refraction is change in direction of light rays. Refraction occurs whenever light rays travels from a transparent medium to another transparent medium of different density. The abrupt change in direction at the surface of the surface of the two media is referred to as <em>refraction</em><em>.</em>

<em>Refraction occurs when light travels from air to glass or from air to liquid.</em>

<em>Laws Of Refraction:</em>

(i) The incident ray, the refracted ray and the normal, all at the point of incident lies in the same plane.

(ii) The ratio of the sine of the angle of incident to the sine of the angle of refraction is a constant for a given pair of media.

<em>Thus the right option is D. refraction</em>

Your diagram is a muscle that helps you breathe. do you think this muscle is voluntary or involuntary? Explain.
PIT_PIT [208]
The diaphragm is primarily an involuntary muscle. Although voluntary means can be achieved, such as when you hold your breath while swimming, this is temporary as the diaphragm will eventually work on its own to supply your body with oxygen.

What is the difference between diatomic and poly-atomic molecules? Site some examples.
Olegator [25]
Their difference lies in the prefix used before each root word, atom. The diatomic molecules are composed only of 2 atoms such as that of the diatomic elements: H2, O2, N2, Cl2, etc. On the other hand, polyatomic molecules are made up of three or mole atoms such as NH4+, H2SO4, etc.

koban [17]

A) Radio waves are a form of electromagnetic radiation.

TRUE

It is the type of electromagnetic wave with least energy range and longest wavelength range among all

B) Electromagnetic radiation does not require a medium to travel.  

TRUE

This radiation can travel through vacuum also and its speed is maximum in vacuum

C) In a vacuum, electromagnetic radiation travels at the speed of light.

TRUE  

speed of all electromagnetic radiation is same as speed of light in vacuum

D) Electromagnetic radiation travels in the form of longitudinal waves.

FALSE

All electromagnetic radiation is always in form of transverse waves

So correct options are

tangare [24]

Answer:

56.86153 N

Explanation:

t =Time taken

F = Force

Power

P=\frac{W}{t}\\\Rightarrow W=P\times t\\\Rightarrow W=77\times 0.96\\\Rightarrow W=73.92\ Joules

Work done

W=F\times s\\\Rightarrow F=\frac{W}{s}\\\Rightarrow F=\frac{73.92}{1.3}\\\Rightarrow F=56.86153\ N

The magnitude of the force that is exerted on the handle is 56.86153 N
