a wave is represented by the equation y=2sinx (0.5x-700t) where all distances are measured in centimeter and time in seconds. for this wave calculate it. (1) frequency (2)wavelength (3)speed

Using y= Asin(kx-wt)

y= 2sinx(0.5x-700t)

By comparison

Omega(w) = 700

But w= 2πf= 700

Frequency= 700/2π= 111.4Hz

2.

K = 2π/ wavelength

So k= 0.5

So wavelength= 2π/0.5= 12.6cm

3.

Speed= wavelength x frequency

= 111.4* 12.6= 1403.6cm/s

f = 350/π

λ = 4π

v = 14 m/s

Explanation:

y = 2 sin(0.5x - 700t)

y = A sin(kx - ωt), comparing both with each other, we will realise that

A = 2

k = 0.5

ω = 700

A is the amplitude,

k is the phase constant and

ω is the angular frequency

k = 2π/λ, and we know k = 0.5 too, thus

0.5 = 2π/λ

λ = 4π

f = ω/2π

f = 700 / 2π

f = 350 / π

f = 111.39, approximately 111 Hz

v = fλ

v = 350/π * 4π

v = 350 * 4

v = 1400 cm/s

v = 14 m/s

therefore, wavelength is 4π, speed is 14 m/s, and frequency is 350/π

your answer is, orbit around the nucleus

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
