The inverse variation equation shows the relationship between wavelength in meters, x, and frequency, y.

Vaselesa [24]

Answer: The wavelength for X-rays with the given frequency is $1\times 10^{-10}m$

Step-by-step explanation:

To calculate the wavelength of light, we use the equation:

$\lambda=\frac{c}{\nu}$

where,

$\lambda$ = wavelength of the light

c = speed of light = $3\times 10^8m/s$

$\nu$ = frequency of light = $3\times 10^{18}s^{-1}$

Putting the values in above equation, we get:

$\lambda=\frac{3\times 10^8m/s}{3\times 10^{19}s^{-1}}=1\times 10^{-10}m$

Hence, the wavelength for X-rays with the given frequency is $1\times 10^{-10}m$

Please answer this correctly which is the correct options

MakcuM [25]

The first two are equivalent to 15 = k + 13

8 = k + 13 - 7 → ( add 7 to both sides )

8 + 7 = k + 13 ⇒ 15 = k + 13 ' is equivalent '

12 = k + 13 - 3 → ( add 3 to both sides )

12 + 3 = k + 13 ' is equivalent '

If two measurements are very close to each other, then they are ____..

erik [133]

The correct answer is:

B) precise

Explanation:

Precision can be broken down into two pieces:

Repeatability - The variation observed when the same person measures the same thing repeatedly with the same device.

Reproducibility: The variation observed when different people measure the same thing using the same device.

If two measurements are very close to each other, this gives repeatability. If the measurements were made by different people, this gives reproducibility.

Accuracy, however, describes the difference between the measurement and the thing's actual value. This would not involve getting the same result repeatedly; it would be getting the correct value.
