If the wavelength is doubled what happens to the period

1 answer:

3 0

Answer: Wave speed may equal frequency*wavelength. Yet doubling the frequency only halves the wavelength; wave speed remains the same. To change the wave speed, the medium would have to be changed. 24. What are some simple steps I can take to protect my privacy online? Many people ... So if you double the frequency and keep the speed constant, the wavelength halves to give the same speed with the doubled frequency. 3.8k views ... The period of a note is 0.3 seconds and the speed of sound in air is 340 m/s. So if you double the frequency and keep the speed constant, the wavelength halves to give the same speed with the doubled frequency. What is the period of a wave if the wavelength is 100m and the speed is 200 m/s? ... If you move towards a light source, the wavelength decreases.

The ratio of T1 : T2 is 1.6

<h3>What is Simple Harmonic Motion ?</h3>

SHM is the periodic motion of a particle along a line such that the acceleration of the body is directed toward a fixed point and proportional to its displacement.

Given that a pendulum of length 130.0 cm has a period of oscillation, T₁.

Then, The period T₁ = 2 $\pi$ $\sqrt{\frac{l}{g} }$

T₁ = 2 x 3.142 $\sqrt{\frac{1.3}{10} }$

T₁ = 6.284 x 0.36

T₁ = 2.266

But if T = 0

then, m $v^{2}$ /r = mg

the m will cancel out

Then v = $\sqrt{rg}$

where r = 50/100 = 0.5m

Substitute into the formula

v = $\sqrt{ 0.5 * 10}$

v = 2.24 m/s

Also, given that the bob is pulled and released to move in a horizontal circle of radius 50.0 cm and the period of rotation is T2,

w = 2 $\pi$ f

w = 2 $\pi$ /T

but v = wr

w = v/r

Therefore,

v/r = 2 $\pi$ /T

Substitute all the parameters into the formula

2.24/0.5 = (2 x 3.1423) /T

T = 6.284/4.472

T = 1.405 = $T_{2}$

The ratio T₁: T2 will be 2.266/1.405

The ratio is 1.6

Nostrana [21]

The correct answer is:

D. Extrusive rocks.

The explanation:

when extrusive igneous rocks form when magma reaches the Earth's surface a volcano and cools quickly. Most extrusive (volcanic) rocks have small crystals. Examples include basalt, rhyolite, andesite, and obsidian.
