A) proton

This is simply a matter of actually learning the terms. To wit
A) proton - One of two different particles found in the nucleus of an atom. They have about the same mass as a neutron, and have a positive charge.

B) photon - The basic unit of light.

C) neutron - The other particle found in the nucleus of an atom. They have no electrical charge and are about the same mass as a proton.

D) electron - The particle that "orbits" the nucleus of an atom. They're much lighter than either protons or neutrons, and have a negative charge.

Which phrase best describes sir isaac newton's contributions to modern science and therefore to the industrial revolution?

astraxan [27]

Can you please give the phrases?

But, I'll help what I can.

First, he was the first to discover gravity. He was not bonked by the head by an apple, rather he watched an apple fall from a tree before he decided to explore gravity further.

He was also the first scientist to be knighted, which is a great honor, as you can expect.

Newton also developed The Three Laws of Motion. They are extremely important to physics and are considered some of the foundation for physics today.

He also discovered calculus, which is complex math that is very helpful to scientists today.

He also discovered the color spectrum using a glass prism, a dark room and window shade with a hole in it. He was able to project the color spectrum onto a piece of paper.

Those are the few I can think of now, but hope it helps!

A light beam travels at 1.94×108 in quartz. The wavelength of the light in quartz is 355 .Part AWhat is the index of refraction

Alja [10]

A) 1.55

The speed of light in a medium is given by:

$v=\frac{c}{n}$

where

$c=3\cdot 10^8 m/s$ is the speed of light in a vacuum

n is the refractive index of the material

In this problem, the speed of light in quartz is

$v=1.94\cdot 10^8 m/s$

So we can re-arrange the previous formula to find n, the index of refraction of quartz:

$n=\frac{c}{v}=\frac{3\cdot 10^8 m/s}{1.94\cdot 10^8 m/s}=1.55$

B) 550.3 nm

The relationship between the wavelength of the light in air and in quartz is

$\lambda=\frac{\lambda_0}{n}$

where

$\lambda$ is the wavelenght in quartz

$\lambda_0$ is the wavelength in air

n is the refractive index

For the light in this problem, we have

$\lambda=355 nm\\n=1.55$

Therefore, we can re-arrange the equation to find $\lambda_0$ , the wavelength in air:

$\lambda_0 = n\lambda=(1.55)(355 nm)=550.3 nm$

A 34.0 kg sled is accelerated by a constant force of 45.0 N from 2.00 m/s to 16.00 m/s. For how long was the force acting on the

goblinko [34]

Answer: 10.6 sec

Explanation:

Because I got it right on my quiz :D

also because you can use the impulse momentum formula, Ft=m(triangle)v

so basically u do 16m/s-2m/s=14m/s and thats your triangle v (change in velocity) then multiply 14 times the mass, which is 34. Thats 476, so now you have ft=476, and you know F, the force, so all you have to do is divide 476 by 45, and you get like 10.5777777 which rounds up to 10.6!

Why do we need to learn about median and mode?

siniylev [52]

We need to learn about median and mode because they are both important in statistical data and statistical data is what shows us important information about the world around us.
