A 85.0 cm wire of mass 9.40 g is tied at both ends and adjusted to a tension of 39.0 N . When it is vibrating in its second over

tone, find the frequency at which it is vibrating. When it is vibrating in its second overtone, find the frequency of the sound waves it is producing. When it is vibrating in its second overtone, find the wavelength of the sound waves it is producing.

Answer:

frequency = 104.80 Hz

wavelength = 0.567 m

frequency = 104.80 Hz

wavelength = 3.27 m

Explanation:

given data

mass m = 9.4 g = 9.4 ×10^{-3} m

length L = 85 cm = 0.85 m

tension  T = 39 N

to find out

frequency and wavelength

solution

first we find frequency for second overtone

f = 3 /2L × √(T/μ)   .............1

put here all value and

here μ = m/L = 9.4 ×10^{-3} / 0.85 = 1.10588 ×10^{-2} kg/m

f = 3 /2(0.85) × √(39/1.10588 ×10^{-2})

f = 104.80 Hz

and

wavelength is 2L/3

wavelength = 2(0.85) / 3

wavelength = 0.567 m

and

frequency = 104.80 Hz

and

wavelength by speed of sound i.e 343 m/s

wavelength = speed / f

wavelength = 343 / 104.80

wavelength = 3.27 m

Answer:

45000 kg and 45 tons  

Explanation:

The expression in kilograms and tons is shown below;

As we know that

1 gr is 0.001 kg

So, 45000000 = 45,000 kg

And,

1 kg = 0.001 tons  

So, 45000 kg = 45 tons    

Therefore the same would be considered

Give 1 real life example of a scenario that takes advantage of the inverse relationship between force and time when impulse is c
OverLord2011 [107]

Answer:

On real life example of a scenario that takes advantage of the inverse relationship between force and time when impulse is constant is when making a serve with a lawn tennis racket

How It is an example of impulse is that when a serve is made by moving the bat slowly, the lawn tennis player uses less force and the ball is in contact with the string for longer a period

When however, the lawn tennis player moves the racket faster, with the strings of the racket highly tensioned  he uses more force and the ball also spends less time on the racket to produce the same momentum

Explanation:

The impulse of a force, ΔP is given by the following formula;

ΔP = F × Δt

Where ΔP is constant, we have;

F ∝ 1/Δt

Therefore, for the same impulse, when the force is increased, the time of contact is decreases and vice versa.
