<span>So we want to know what kind of wave is the scientist is studying while studying earthquakes. Waves that produce earthquakes are mechanical waves. Gamma rays and radiowaves are both electromagnetic waves and don't require a medium but mechanical do. So the correct answer is mechanical waves.</span>
Answer:
a) 2seconds.
Explanation:
The period of oscillation will not change . It will still be 2seconds although the length was doubled to 8cm.
This is because the amplitude does not change oscillation time.
Well, collinear points are points in same line,
that is a straight line is formed by connecting them,
here the line segment mE has point A,G,C,E so all these are collinear..
so, option c) E will be answer
hope it helped
Diamonds are supposed to formed about 90 miles below the surface of the earth in the mantle. Therefore, the weight of the earth overhead them produces the pressure to form the diamond. The rocks weight overhead the mantle outcomes in high pressure and diamonds essential high temperatures and pressure to form as of carbon.Diamonds form in the mantle in definite precincts where situations are right for them to do so. There just chances to be the right critical temperature-pressure-mineral environment in the mantle in definite areas for their formation.
Answer:
See solution below
Explanation:
The standard equation of a wave is represented by: Y = Asin 2π(x/λ – ft)
A is the amplitude
λ is the wavelength
f is the frequency
t is the time
Comparing the standard with the given equation Y = 0.005sin 2π(0.5x – 200t)
i) A = 0.005m
Amplitude is 0.005m
ii) ω = 2πf
ω = 2π(200)
ω = 400π rad/s
iii) ω = 2πf
400π = 2πf
200 = f
Swap
f = 200Hertz
iv) Period = 1/f
Period = 1/200
Period = 0.005secs
v) wave number =
vi) Wavelength λ
0.5x = x/λ
0.5 = 1/λ
λ = 1/0.5
λ = 2m
vii) velocity - fλ
velocity = 200 * 2
velocity = 400m/s
