Answer:
The hypothesis as to what happened to the soda and the air in the can are as follows;
The solubility of air in the soda is high at low temperatures, such that air (carbon dioxide, CO₂) is trapped in the soda and when it is drank, it gives it its fresh taste
By placing the can of soda on the hot plate, drives off the air in the soda such that the space directly above the liquid soda is filled with the original air (carbon dioxide), in the soda
By dipping the soda upside down in the sink half filled with water, the soda is cooled down and the air (carbon dioxide) directly above the surface of the liquid soda is reabsorbed into the liquid soda, such that if the lid of the soda is sealed, the vacuum created by the empty space directly above the liquid soda becomes a region of low pressure and the combined pressure from the atmosphere and the liquid level in the sink, causes the can to immediately crushed (deformed).

Answer:
f2 = 140 Hz
Explanation:
let fundamental frequency is f1 = 70.0 Hz
formula for finding the higher frequency when fundamental frequency is known
fn = n f1 (where f1 is fundamental frequency and n = 1,2,3,4,5...........)
for the second frequency n=2
f2 = 2 × 70.0 Hz
f2 = 140 Hz
