Mass in physics is in kg and mass in chemistry is in grams. Therefore a person's mass is kg
Answer:
The value is
Explanation:
From the question we are told that
The first amplitude of the wave is
The first depth is
The second amplitude is
The second depth is
Generally from the spatial wave equation we have
=>
So considering the ratio of the equation for the two depth
=>
=>
=>
Answer:
f = 1.18 x 10¹¹ Hz
Explanation:
The equation used to find frequency is:
f = c / w
In this form, "f" represents the frequency (Hz), "c" represents the speed of light (3.0 x 10⁸ m/s), and "w" represents the wavelength (m).
Since you have been given the value of the constant (c) and wavelength, you can substitute these values into the equation to find frequency.
f = c / w <---- Formula
f = (3.0 x 10⁸ m/s) / w <---- Plug 3.0 x 10⁸ in "c"
f = (3.0 x 10⁸ m/s) / (2.55 x 10⁻³ m) <---- Plug 2.55 x 10⁻³ in "w"
f = 1.18 x 10¹¹ Hz <---- Divide
A scalar quantity is a measurement of a quantity, like temperature, or mass.
