Answer:
Volume needs to increase with increased depth
Explanation:
The pressure on the fish body will increase as the fish dives. This increased pressure will lower the volume of the air bladder roughly along the lines of
PV = nRT
To maintain neutral buoyancy, the bladder volume will have to be increased to displace the same amount of water as before.
Answer:
161.938 Hz
Explanation:
the computation of the fundamental resonant frequency is shown below
p = 1100 kg/m^3
A = 130 mm^2
= 130 ×10^-6 m^2
T = 600 N
L = 20 cm
= 0.2 m
Now the linear density of tendon is
= 1100 kg/m^3 × 130 ×10^-6
= 0.143 kg/m
Now the wave of the string is
= √600 ÷ √0.143
= 64.775 m/s
Now finally the fundamental resonant frequency is
= 64.775 ÷ (2 × 0.2)
=161.938 Hz
Answer: this is constructive interference and superposition is sum of both waves.
Explanation: when crests overlap you add amplitudes together
Answer:
Distance = 0.35 miles
Displacement = 0 miles
Explanation:
The distance covered Ryan is the sum of the diatances moved from his house and then back to his house. According to the question, after covering 0.35 miles, Ryan arrived back in his house. Hence, distance covered by Ryan is 0.35 miles.
Displacement refers to overall change in position of an object from a certain starting position.
In the scenario above, Ryan's Displacement from is house will be zero, since ;
Starting position is his house and his final position is his house.
Hence, change in position or distance from his house = 0 miles
Speed = distance/time
Speed of car = 125 km/2 hours
Car speed = 62.5 km/hr.
