A particular sound wave can be graphed using the function y=1 sin 4x. Find the amplitude and period of the function
2 answers:
The amplitude is equivalent to the coefficient of the sine function, so:
Amplitude = 1
The time period of a Sin(x) = 2π
The time period of Sin(4x) = 2π/4 = π/2
The period is π/2

Answer:
0.28m/s²
Explanation:
Force = mass•acceleration
F = m•a
50 = 176•a Divide both sides by 176:
50/176 = a ≈ 0.28 m/s²
(-2, -1)(3, 1)
Therefore,
Mass = Density * Volume
Density = 19.3 g/cm³
Volume = 24 cm³
Mass = Density * Volume = 19.3 g/cm³ * 24 cm³ = 463.2 g
Mass = 463.2 g

Explanation:
In case of colored film we apply the theory of interference.
Condition that colored fringe is formed ( constructive interference)
2μt = λ/ 2 ( minimum order)
t = λ/ 4μ
= 540 / 4 x 1.38
= 97.83 nm
