Answer:
Mechanical Advantage = Output Force/Input Force
Velocity Ratio = Driving Gear/Driven Gear
Explanation:
Frequency and wavelength are inversely proportional.
A shorter wavelength implies a higher frequency.
Unless the ring by design will have restriction for any outward expansion. The hole will get larger / bigger as you heat this up. The more you heat an object the more it expands, thus the larger the hole gets. The only case is when outward expansion is restricted, the expansion will be inward as it is the only direction the ring can expand to.
Answer:
The length is 
Explanation:
From the question we are told that
The length of the wire 
The mass is 
The tension is 
Generally the frequency of oscillation of a stretched wire is mathematically represented as

Where n is the the number of nodes = 3 (i.e the third harmonic)
is the linear mass density of the wire
This linear mass density is mathematically represented as
Substituting values


Substituting values in to the equation for frequency


From the question the we can deduce that the fundamental frequency is equal to the oscillation of a stretched wire
The fundamental frequency is mathematically represented as

Where
is the length of the pipe
v is the speed of sound with a value of 
Making
the subject of the formula
Substituting values


From the question the we can deduce that the fundamental frequency is equal to the oscillation of a stretched wire
Answer:
radial velocity = 0.533 ×
m/s
Explanation:
given data
observed wavelength = 394.0 nm
rest wavelength = 393.3 nm
solution
we get here radial velocity by the Doppler effect of light that is
......................1
v =
put here value
v = \frac{c \times (\lambda ' - \lambda }{\lambda}
v = \frac{3 \times 10^8 \times (394 - 393.3}{393.3}
v = 533943.55
v = 0.533 ×
m/s
