Answer:
Height of ramp = 17.49 m
Explanation:
We have equation of motion ,
, s is the displacement, u is the initial velocity, a is the acceleration and t is the time.
Considering horizontal motion of skier
Initial velocity = 33 m/s, Displacement = 63 m, acceleration = 0 and we need to find time taken to reach ground by the skier.
![63= 33t+\frac{1}{2} *0*t^2\\ \\ t=1.909seconds](https://tex.z-dn.net/?f=63%3D%2033t%2B%5Cfrac%7B1%7D%7B2%7D%20%2A0%2At%5E2%5C%5C%20%5C%5C%20t%3D1.909seconds)
The vertical distance traveled in 1.909 seconds is the height of ramp
Initial velocity = 0 m/s, acceleration = acceleration due to gravity = 9.8
, time = 1.909 s and we need to find displacement.
![s= 0*1.909+\frac{1}{2} *9.8*1.909^2\\ \\ s=17.49 m](https://tex.z-dn.net/?f=s%3D%200%2A1.909%2B%5Cfrac%7B1%7D%7B2%7D%20%2A9.8%2A1.909%5E2%5C%5C%20%5C%5C%20s%3D17.49%20m)
So height of ramp = 17.49 m
Answer:
If the beer is in the crystal clear glass, unprotected from the sunlight then it will starts skunking within 30 seconds. The reason behind the skunking of the beer is a photo chemical reaction. So one can avoid the skunking of beer by packaging it in the cans or opaque bottles.

Answer:
Approximately 4.029 A
Explanation:
We can use the formula that the B field of a few loops all with current in same direction is permeability of free space (mu)* current * Number or loops divided by 2*radius. You are given B field, radius(convert into meters), number of loops and mu is 4pi * 10^-7. Solve for current and you get 4.029 Amperes.
