Two masses, A and B, are attached to different springs. Mass A vibrates with an amplitude of 8 cm at a frequency of 10 Hz and ma

Anettt [7]

To solve this problem we will apply the concepts of speed given the simple harmonic movement, for which it defines this speed as

$v_{max} = \omega A$

Here

$\omega =$ Angular velocity

A = Amplitude

Recall that the angular velocity is equivalent in terms of the frequency at

$\omega = 2\pi f$

If we replace the value we will have then

$v_{max} = 2\pi f A$

For mass A

$v_{max,A} = 2\pi (10)(0.08) = 5.024m/s$

For mass B

$v_{max.B} = 2\pi (16)(0.05) = 5.024m/s$

Therefore they are equal.

The wavelengths of visible light vary from about 300 nm to 700 nm. What is the range of frequencies of visible light in a vacuum

exis [7]

The range of frequencies of visible light in a vacuum is mathematically given as

Fmin=4.19*10^14Hz to Fmax=1*10^15Hz

<h3>What is the range of frequencies of visible light in a vacuum?</h3>

Question Parameters:

The wavelengths of visible light vary from about 300 nm to 700 nm.

Generally, the equation for the frequency is mathematically given as

F=C/\lambda

Therefore

For Fmax

$Fmax=\frac{300*10^8}{3*10^9}$

Fmax=1*10^15Hz

Where

$Fmin=\frac{3*10^8}{700*10^9}$

Fmin=4.19*10^14Hz

Pressure can affect the density of Solids Liquids Gases Metals

gtnhenbr [62]

Answer;

-Gases

Explanation;

-Pressure can affect the density of gases.

-Density of gases changes with pressure and temperature because gases are compressible fluid and because they are compressible, when pressure increases molecules come closer to each other which means increase in density and when pressure drops molecules of gases become free to expand and get away from each other which density decrease.
