the resolution of a camera or other optical system is determined by the relationship between what two scales?

Triss [41]

The resolution of a camera or other optical system is determined by the relationship between that two scales of Light waves of different wavelengths produce diverse colors.

A waveform signal that is carried in space or down a wire has a wavelength, which is the separation between two identical places (adjacent crests) in the consecutive cycles. This length is typically defined in wireless systems in meters (m), centimeters (cm), or millimeters (mm) (mm).

The distance between the crests or troughs of a wave motion is referred to as the wavelength () of light. 2. Frequency (f) - The frequency of a repeated event is the number of instances per unit of time. Frequency in the context of light is the number of wavelength repetitions per second.

A 580-mm long tungsten wire, with a 0.046-mm-diameter circular cross section, is wrapped around in the shape of a coil and used

Bad White [126]

Answer:

$N=1.64\times10^{19}$

$R=19.54\Omega$

$V=10.28V$

Explanation:

By definition $I=Q/t$ , so we can calculate the total charge that went through the filament since we know the electric current and the time. If the charge of one electron is e, then the total charge will be given by Q=Ne. Combining these equations we get the number of electrons as:

$N=\frac{Q}{e}=\frac{It}{e}=\frac{(0.526A)(5s)}{1.602\times10^{-19}C}=1.64\times10^{19}$

Since the resistivity of tungsten (W) is $\rho_W=5.6
\times10^{-8}\Omega m$ , then resistance can be calculated using the formula:

$R=\rho_W\frac{L}{A}=\rho_W\frac{L}{\pi r^2}=(5.6\times10^{-8}\Omega m)\frac{(0.58m)}{\pi (0.000023m)^2}=19.54\Omega$

Where we already obtained the radius from the diameter. Finally the Voltage will be given by the formula:

$V=RI=(19.54\Omega)(0.526A)=10.28V$

If a characteristic of a parent, such as eye color,does not show up in offspring ,is it gone forever

mihalych1998 [28]

No it is not. It is still apart of the offspring's DNA. In fact it might show up in the very next generation!

Recall the raisin cake model of the universe. Our universe is expanding between the galaxies. You measure the recession velocity

Rina8888 [55]

Explanation:

Recession velocity of a galaxy is related to the distance at which the galaxy is located. This relationship is given by the hubble constant, as follows:

$v_r=HD$
