Answer:

C. A Tsunami

Explanation:

When there are earthquakes, volcanic eruptions or some underwater disturbances, a hue amount of water is displaced in the form of huge waves in a sea. This is known as tsunami.

In 2004 a major tsunami was caused by an undersea earthquake, in Indian Ocean, resulting in waves as high as 30 meters and affected 15 countries. Indonesia, Sri Lanka, and India were the worst affected countries.

Katyanochek1 [597]

Answer:

9.88 milivolt

Explanation:

Given: diameter d = 5.2 cm

magnetic field B_1 = 1.35 T, final magnetic field B_2 =0 T

t = 0.29 sec.

we know emf = - dΦ/dt

and flux Φ = BA

A= area

therefore emf ε = -A(B_2-B_1)/Δt

$=-\pi(d/2)^2\frac{B_2-B_1}{\Delta t} \\=-\pi(0.052/2)^2\frac{0-1.35}{0.29} \\=98.8\times10^4\\=9.88 mV$

How does reflection differ from refraction and diffraction?

shtirl [24]

Answer: Reflection is the only process in which the wave does not continue moving forward.

Explanation:

Reflection is a process in which the direction of the wave changes when it is exposed to a bounce off barrier. Refraction can be defined as the change in the direction of the wave when the wave passes through one medium to another. Diffraction is a process in which the direction of the wave changes when the wave passes through a particular opening near the barrier.
