The height above the ground from where the skier start is 11.5 m.
<h3>
Conservation of energy</h3>
The height above the ground from where the skier start is determined by applying the principle of conservation of energy as shown below;
P.E = K.E
mgh = ¹/₂mv²
gh = ¹/₂v²
Thus, the height above the ground from where the skier start is 11.5 m.

Answer:
The unit rate is $0.22 lb
Explanation:
The given parameters are;
The price for 18 lb = $3.99
We have;
The unit rate is the price for one unit. Whereby the unit of measurement is the lb, we have that one unit = 1 lb.
Therefore, given that 1 lb = 18 lb/18, the price of 1 lb which is the unit rate is given as follows;
18 lb price = $3.99
Divide both sides by 18 to get;
18 lb/18 = $3.99/18 = $0.221
Therefore, we have;
1 lb = 18 lb/18 = $0.221
The unit rate, which is the cost for 1 lb to the nearest hundredth = $0.22/lb.
Displacement is the amount of "ground" and object moves from it starting point and distance is how much "ground" an object covers in total. Displacement by definition is moving of something from its place or position and distance by definition is the amount of space between two things (in this case the starting position and ending position).ΥΤ-ΤΟΝΙХWΙLSΟΝ
The best way to look at it is the other way around.
Electromagnetic waves exist over a huge range of frequencies, from less
than 1 per second up to more than 3 billion billion billion per second.
If electromagnetic waves with frequencies between maybe about
4 million billion per second up to about 7.5 million billion per second
go into your eye, you SEE them.
Outside of that range, your eye doesn't know that there's anything there. But
IN that range, your eye has incredible nerve ends in the back that can tell the
difference between different frequencies. The highest frequencies in that range
produce the feeling of blue in your brain. The next highest ones make a feeling
of green. The next highest ones make the impression of yellow, and so on and
so on, down to the lowest frequencies that your eye can detect, and those look
red. If the frequency is any lower than red, you don't see it even when it pours
into your eyes.
