Answer:
2a.) Wavelength = 1.8 m
2b.) F = 66.67 Hz
3a.) Find the attached file
3b.) Wavelength = 0.6 m
Explanation:
Given that the
Length L = 0.9m
Wavelength (λ) = 2L/n
Where n = number of harmonic
If n = 1, then
Wavelength (λ) = 2L = 2 × 0.9 = 1.8 m
b.)
If waves travel at a speed of 120m/s on this string, what is the frequency
associated with the longest wave (first harmonic)?
Given that V = 120 m/s
V = Fλ
But λ = 2L, therefore,
F = V/2L
F = 120/1.8
F = 66.67 Hz
3. b.) If there are two node, the position will be in 3rd position which is 3rd harmonic
Using the same formula,
Wavelength (λ) = 2L/n
Where n = 3
Wavelength (λ) = 2 × 0.9/3
Wavelength (λ) = 0.6 m
Answer:
Explanation:
Work is given by the equation 
where 
is force and 
is displacement.
Displacement is defined as change in position. In this case, the box moves from 5m to 20m. Its displacement is 
.
The force acting on the box is the force of gravity, given as 
.
Therefore, the total work done is:
(two significant figures).
Answer:
A convex mirror is sometimes referred to as a diverging mirror due to the fact that incident light originating from the same point and will reflect off the mirror surface and diverge. ... After reflection, the light rays diverge; subsequently they will never intersect on the object side of the mirror.
Explanation:
The mass will accelerate. Balanced Forces: When forces are in balance, acceleration is zero<span>. </span>
An input device sends information to a computer system for processing, and an output device reproduces or displays the results of that processing. Input devices only allow for input of data to a computer and output devices only receive the output of data from another device.
Hope it helps!
