A water strider bug is supported on the surface of a pond by surface tension acting along the interface between the water and th

Alik [6]

Answer:

minimum interface length = 1.36 mm

Explanation:

given data

weight of the bug = $10^{-4}$ N

solution

we will apply here Surface Tension formula that is

Surface Tension ,σ = Force ÷ length ........................1

and we consider here surface tension for water is 7.34 × $10^{-2}$ N/m

so that here minimum interface length needed to support the bug is

minimum interface length = Force ÷ σ

minimum interface length = $10^{-4}$ ÷ 7.34 × $10^{-2}$

minimum interface length = 1.36 mm

The speed of light in a transparent medium is 0.6 times that of its speed in vacuum. Find the refractive index of the medium.

grin007 [14]

<h2>Answer:</h2>

The refractive index is 1.66

<h2>Explanation:</h2>

The speed of light in a transparent medium is 0.6 times that of its speed in vacuum .

Refractive index of medium = speed of light in vacuum / speed of light in medium

RI = 1/0.6 = 5/3 or 1.66

Which of the following represents the wavelength of a wave?

dlinn [17]

Answer: D. the distance between the highest points of consecutive waves

Explanation:

The wavelength of a wave is defined as the <em>distance traveled by a periodic perturbation that propagates through a medium in a given time interval</em>. It is usually represented by $\lambda$ and can be calculated if the frequency of the wave is known, since there is an inverse relationship between both.

In the specific case of a periodic sine wave (which is the way in which a wave is usually represented graphically) the wavelength can be determined as the distance between two consecutive maxima of the disturbance.

Therefore, the correct option is D.
