A right triangle has sides measuring 5 and 12 inches. If the two vectors have a magnitude of 5 and 12 and are at right angles to
ollegr [7]

Answer:

x=13

Explanation:

From the question we are told that

Magnitude 1 M_1=5

Magnitude 1 M_2=12

Generally the Pythagoras equation for the magnitudes is mathematically given as

\sqrt{x^2}=\sqrt{M_1^2 +M_2^2}

\sqrt{x^2}=\sqrt{5^2 +12^2}

x=13

Therefore resultant magnitude is

x=13

An electromagnetic wave has a frequency of 6.0 x 10^18 Hz. What is the
jonny [76]

Answer:

Wavelength = 5 * 10^{-11} meters

Explanation:

Given the following data;

Frequency = 6.0 x 10^18 Hz

Speed = 3 * 10⁸ m/s

To find the wavelength of the wave;

Mathematically, the wavelength of a wave is given by the formula;

Wavelength = \frac {speed}{frequency}

Substituting into the formula, we have;

Wavelength = \frac {3 * 10^{8}}{6.0 x 10^{18}}

Wavelength = 5 * 10^{-11} meters
