Answer:
Explanation:
Answer:
4.53 kg
Explanation:
spring constant, K = 16 N/m
Amplitude, A = 20 cm = 0.2 m
Maximum speed, v = 37.6 cm/s = 0.376 m/s
The formula for maximum speed is given by
v = ωA
where, ω is the angular frequency
0.376 = ω x 0.2
ω = 1.88 rad/s
m = 4.53 kg
Thus, the mass of banana bunch is 4.53 kg.
Since the temperature of the gas remains constant in the process, we can use Boyle's law, which states that for a gas transformation at constant temperature, the product between the gas pressure and its volume is constant:
which can also be rewritten as
(1)
where the labels 1 and 2 mark the initial and final conditions of the gas.
In our problem,
, 
and 
, so the final pressure of the gas can be found by re-arranging eq.(1):
Therefore the correct answer is
<span>1. 0.75 atm</span>
which can also be rewritten as
where the labels 1 and 2 mark the initial and final conditions of the gas.
In our problem,
Therefore the correct answer is
<span>1. 0.75 atm</span>
