What is electromagnetic waves?The oscillations between an electric field and a magnetic field produce waves known as electromagnetic waves, or EM waves. In other words, magnetic and electric fields oscillate to form electromagnetic (EM) waves.
When an electric field interacts with a magnetic field, electromagnetic waves are created. Therefore, they are referred to as "electromagnetic" waves. An electromagnetic wave's electric field and magnetic field are perpendicular to one another (at right angles). Additionally, they are perpendicular to the EM wave's direction. An electromagnetic wave can pass through any medium, including vacuum, solid materials, and air. It can spread or move from one area to another without the use of a medium.

A skier waits at the top of a 11.7m hill. He then skis down the slope at an angle of 27 degrees above horizontal. What will his velocity be at the bottom of the hill? Show work
Answers
Answer:
v = 3.89 m / s
Explanation:
For this exercise let's use the concept of conservation of mechanical energy
starting point. In the highest part of the mountain
Em₀ = U = m g h
final point. In the lower part
Em_f = K = ½ m v²
how energy is conserved
Em₀ = Em_f
mgh = ½ m v²
v = [tex]\sqrt{ 2gh}[/tex]
let's use trigonometry to find the height
sin θ = h / L
h = L sin θ
we substitute
v = [tex]\sqrt{ 2g L \ sin tea}[/tex]
let's calculate
v = [tex]\sqrt{2 \ 9.8 \ 1.7 \ sin 27}[/tex]
v = 3.89 m / s

The diagram below shows a 1.0 x 105newton truck at rest on a hill that makes an angle of 8.0° with the
horizontal. What is the component of the truck's weight parallel to the hill? (hint: the weight was already
calculated, also you can use the work area to help you solve this.]
Answers
Answer:
[tex]it \: is \: mg \sin(8.0 \degree) \\ = 1.0 \times 10 {}^{5} \times \sin(8.0 \degree) \\ = 9.9 \times 10 {}^{4} newtons[/tex]
The component of the truck's weight parallel to the hill is 13,917.31 N.
The given parameters:
Weight of the truck, W = 1.0 x 10⁵ NInclination of the hill, θ = 8⁰The component of the truck's weight parallel to the hill is calculated as follows;
[tex]W_x = mg \times sin(\theta)\\\\W_x = W \times sin(\theta)\\\\W_x = 1\times 10^5 \times sin(8)\\\\W_x = 13,917.31 \ N[/tex]

Answer:
231 C final temperature, 211 C change in temperature
Explanation:
To solve this problem you you use the q=MCΔT equation, where q is heat, m is mass, c is specific heat, and ΔT is change in temperature. Since we're given heat and solving for temperature we rearrange the equation to q/(M*C)=ΔT. At this point we simply plug in the given values to get a ΔT of 211, but this is simply the change in temperature so you add the initial to this to get the final temp.

Q: Is the direction important when calculating speed? Explain.
Answers
Answer:
Depends.
Explanation:
Whether the object is going left or right, the speed will stay the same until friction eventually stops it. However, if, for example, we're talking about an object going straight before veering right, then yes, speed does matter. An object will normally have to speed up or slow down momentarily when changing direction to keep itself sustained on the ground.
So, honestly? It really depends on what we're talking about!
