As a pan is sitting on a stove it begins to heat up. Eventually it may get hot enough that it glows red, meaning it is radiating

electromagnetic waves within the visible portion of the spectrum. What does this situation show us about electromagnetic radiation?
Electromagnetic radiation can only be emitted in the form of visible light.
The hotter an object is, the faster the electromagnetic radiation will travel.
The electromagnetic radiation emitted by an object is not affected by its temperature.
The hotter an object is, the greater the energy of the electromagnetic radiation in emits.

Answer:
Your answer is B.!

When things in general get hotter, the atoms inside move faster and vise versa with cold.

(for example water); if you put water in a pot on a stove to boil, its gets so hot to where the atoms are moving really fast to get it to look like that.

Please mark brainiest! if this answer is wrong, (which I'm pretty sure it isn't) then pick D. :D

1. Traveling by car means you have specific roads to follow. You won’t be able to go straight to Banning high from POLAHS. The 8.4km will be defined as distance. Traveling by helicopter you don’t have roads to follow that means you can fly directly to banning high. 6.8km will be defined as displacement.

2. A) 400m
B)0m
C)d=1/2(vi+vf)t
400=1/2(0+vf)92
8.7m/s
D) 0m/s
E) Not sure but instantaneous velocity refer to velocity at a given point. Average velocity is just the average. Usually instantaneous velocity won’t be same as the average velocity.
Plz like if it helped.

A boy whirls a stone in a horizontal circle of radius 1.4 m and at height 1.5 m above ground level. The string breaks, and the s
balandron [24]

Answer:233.23 m/s^2

Explanation:

Given

radius of circle=1.4 m

Height of stone above ground=1.5 m

Horizontal distance(R)=10 m

It is given at the time of break stone flies horizontally thus stone to cover a height of 1.5 m in time t before reaching ground

1.5=0+\frac{gt^2}{2}

t=0.55 s

Initial horizontal velocity at the time of break is given by u

R=u\times t

10=u\times 0.55

u=18.07 m/s

Therefore magnitude of centripetal acceleration is given by

a_c=\frac{u^2}{r}=\frac{18.07^2}{1.4}=233.23 m/s^2
