Answer:
The magnetic flux through surface is 
Wb
Explanation:
Given :
Magnitude of magnetic field 
T
Radius of circle 
m
Angle between field and surface normal 
25°
From the formula of flux,
Where angle between magnetic field line and surface normal, 
area of circular surface.
Magnetic flux is given by,
Wb
Therefore, the magnetic flux through surface is Wb
Answer:
0.98 g/m
Explanation:
Note: Since Tension and frequency are constant,
Applying,
F₁²M₁ = F₂²M₂............... Equation 1
Where F₁ = Frequency of the G string, F₂ = Frequency of the A string, M₁ = mass density of the G string, M₂ = mass density of the A string.
make M₂ the subject of the equation
M₂ = F₁²M₁/F₂²............... Equation 2
From the question,
Given: F₁ = 196 Hz, M₁ = 0.31 g/m, F₂ = 110 Hz
Substitute these values into equation 2
M₂ = 196²(0.31)/110²
M₂ = 0.98 g/m
Waves transfer energy but not matter
Answer:
instantaneous velocity is a velocity covered at an instant while average velocity is the change in distance/ the change in time taken
