The steel traps the heat more making it hotter,you put this twice by the way.
Answer:
71.4583 Hz
67.9064 N
Explanation:
L = Length of tube = 1.2 m
l = Length of wire = 0.35 m
m = Mass of wire = 9.5 g
v = Speed of sound in air = 343 m/s
The fundamental frequency of the tube (closed at one end) is given by
The fundamental frequency of the wire and tube is equal so he fundamental frequency of the wire is 71.4583 Hz
The linear density of the wire is
The fundamental frequency of the wire is given by
The tension in the wire is 67.9064 N
The answer to your question Tropical Cyclones
Answer:
0.312 m/s
Explanation:
Elastic collisions conserve momentum and kinetic energy
The velocity of the center of mass will not change. It continues at
0.00521(443) / 14.80521 = 0.155893... ≈ 0.156 m/s
To conserve kinetic energy we can think of the center of mass (CoM) as an ideal spring returning to each mass that strikes it an identical speed of collision in the opposite direction.
The CoM sees the target approach at - 0.156 and will see it depart at 0.156 m/s
A ground based observer sees the target depart at the velocity of the CoM plus the relative velocity .
v = 0.156 + 0.156 = 0.312 m/s
