Answer:

d = 2,998 10⁷ m

Explanation:

The speed of an electromagnetic wave is the speed of light

      c = 2,998 10⁸ m / s

This speed is in a vacuum, when the light is in a material medium, its speed is lower than this, even when the order of magnitude is maintained.

Since the speed of a wave is constant, we can use the kinematic relationship

       c = d / t

       d = c t

Let's calculate

      d = 2,998 108 0.1

      d = 2,998 10⁷ m

in the vacuum or air

Use Hooke's Law, which states that the distance a spring stretches (or compresses) from its natural, or equilibrium, length vari
Phantasy [73]

Answer:

706.68 N

Explanation:

By Hooke's law,

F = ke

k=\dfrac{F}{e}

Using the values in the question,

k=\dfrac{265\text{ N}}{0.15 \text{ m}}=1766.7\text{ N/m}

When e = 0.4 m,

F = 1766.7\text{ N/m}\times0.4\text{ m}=706.68\text{ N}

Wavelength is measured in hertz true or false?
g100num [7]
Wavelength is measured in various units of distance (mm, cm, m, etc.). Frequency uses hertz, but that is not what the question is asking. Therefore, the answer is false.
