The correct answer is "3. Both increase"
In fact, the frequency of a vibrating string is given by
where L is the length of hte string, T the tension and
the linear mass density.
We can see that string is made shorter, L decreases, so the frequency f increases. And since the pitch has the same behaviour of the frequency, it increases as well.

Answer:
1328.7032 kg
Explanation:
P = Pressure = 112 kPa
T = Temperature = 285 K
V = Volume = 7023 m³
R = Gas constant = 8.314 J/mol K
From the ideal gas law we have
The mass of gas is given by
The mass of helium in the blimp is 1328.7032 kg
