Answer:
The wavelength will be 33.9 cm
Explanation:
Given;
frequency of the wave, F = 1200 Hz
Tension on the wire, T = 800 N
wavelength, λ = 39.1 cm
Where;
F is the frequency of the wave
T is tension on the string
μ is mass per unit length of the string
λ is wavelength
when the tension is decreased to 600 N, that is T₂ = 600 N
Therefore, the wavelength will be 33.9 cm
The acceleration of the wooden box is 6.17 m/s² towards the west.
<h3 /><h3>What is acceleration?</h3>
Acceleration can be defined as the rate of change of velocity.
To calculate the acceleration of the wooden box can be calculated using the formula below.
Formula:
- F₂-F₁ = ma.................. Equation 1
Where:
- F₂ = Force on the wooden box acting towards west
- F₁ = Force on the wooden box acting towards the east
- m = Mass of the wooden box.
- a = Acceleration of the wooden box
Make a the subject of the equation
- a = (F₂-F₁)/m........................ Equation 2
From the question,
Given:
- F₂ = 270.7 N
- F₁ = 85.7 N
- m = 30 kg
Substitute these values into equation 2
- a = (270.7-85.7)/30
- a = 185/30
- a = 6.17 m/s² towards the west.
Hence, The acceleration of the wooden box is 6.17 m/s² towards the west.
