1) what do you mean "non -examples"

2) energy is something in the physical world. we cannot see fell hear touch etc

but it had different forms: work = pushing or pulling a distance, lifting, moving, heat, light sound electricity, . it is best understood by giving examples of the different forms.

it is an idea that is only about 400 years old in physics

It does NOT mean excitement, as "the football crowd had a lot of energy after the big game"

I like to say it is what ever it is, that allows physical change to happen

3) temperature is what we feel as hot or cold and is a measure of average heat energy of a material.

K.E=18750J
Mass=m=2100kg
Velocity=v

$\boxed{\sf K.E=\dfrac{1}{2}mv^2}$

$\\ \sf\longmapsto 18750=\dfrac{1}{2}2100v^2$

$\\ \sf\longmapsto 18750=1050v^2$

$\\ \sf\longmapsto v^2=\dfrac{18750}{1050}$

$\\ \sf\longmapsto v^2=17.85m^2$

$\\ \sf\longmapsto v=\sqrt{17.85}$

$\\ \sf\longmapsto v=4.1m/s$

What kind of light results when the total spectrum of refracted light is recombined? violet green white red?

ElenaW [278]

Hello
The final light will be white. In fact, each color of the visible spectrum is an electromagnetic wave with its own specific frequency and wavelength. White, instead, does not have a specific frequency: it is the sum of all the different wavelengths of the visible spectrum. Therefore, when recombining the spectrum of the refracted light all the different frequencies recombine together, and their sum gives white light.

Explain the importance of measurement<br>Physics.<br><br>

KiRa [710]

Answer:

Measurements are an important part of comparing things, as they provide the basis on comparing objects to other objects. Measurements allow us to recognize three hours and see how it's shorter than five hours, without having to observe the hours passing by themselves.
