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:
Explanation:
initial velocity, u = 0 m/s
final velocity, v = 30 m/s
Let the mass is m .
Initial kinetic energy, Ki = 1/2 mu² = 0
Final kinetic energy, Kf = 1/2 mv² = 0.5 m x 30 x 30 = 450 m
Specific energy change = change in kinetic energy per unit mass
= 450 m / m = 450 J/kg = 0.45 kJ/kg
Answer:
I am not sure if this is the answer
(B) what is the height of the building if it hits the ground after those 5 seconds.
It is because gravity is not an independent force. Gravity comes as result of warped space time according to the theory of general relativity. Therefore we can’t feel gravity because it’s not a force that pulls or pushes.
Answer:
A pure element.
Explanation:
Calcium, being whatever weight, is a pure element.
