➡ 150hrs.

➡ Time = distance × speed

➡ Time = 15*10

➡ Time = 150hrs ans.

Laura and Elana are discussing how to solve the following problem: "A canary sits 10 m from the end of a 30-m-long clothesline,

horrorfan [7]

Answer:

$f=2.236\ Hz$

Explanation:

Given:

Length of a rope, $l=30\ m$

Position of Canary on the rope from one end, $l_c=10\ m$

Position of Grackle on the rope from another end, $l_g=5\ m$

Tension in the rope, $F_T=200\ N$

linear mass distribution on the rope, $\mu=0.1\ kg.m^{-1}$

We have for the speed of wave on the string:

$v^2=\frac{F_T}{\mu}$

$v^2=\frac{200}{\0.1}$

$v=44.7\ m.s^{-1}$

For canary to be undisturbed we need a node at this location.

Also, at the end close to Canary there must be a node to avoid any change in pattern of vibration.

So,

the distance between Canary and the closer end must be equal to half the wavelength.

$\frac{\lambda}{2} =10\ m$

$\Rightarrow \lambda=20\ m$

∴Wavelength of wave to be produced = 20 m. This will give us nodes at the multiples of 10 and anti-nodes at the multiples of 5.

Now, frequency:

$f=\frac{v}{\lambda}$

$f=\frac{44.7}{20}$

$f=2.236\ Hz$

If a distant galaxy has a substantial redshift (as viewed from our galaxy), then anyone living in that galaxy would see a substa

mario62 [17]

Answer:

Option A

Explanation:

The statement makes sense since it's already explained that the galaxy is moving away from us and unlike option C which depicts that the galaxy is moving to us.

This statement makes sense. The redshift means that we see the galaxy moving away from us, so observers in that galaxy must also see us moving away from them—which means they see us redshifted as well

Consider the hydrogen atom. How does the energy difference between adjacent orbit radii change as the principal quantum number i

Kisachek [45]

Answer:

the energy difference between adjacent levels decreases as the quantum number increases

Explanation:

The energy levels of the hydrogen atom are given by the following formula:

$E=-E_0 \frac{1}{n^2}$

where

$E_0 = 13.6 eV$ is a constant

n is the level number

We can write therefore the energy difference between adjacent levels as

$\Delta E=-13.6 eV (\frac{1}{n^2}-\frac{1}{(n+1)^2})$

We see that this difference decreases as the level number (n) increases. For example, the difference between the levels n=1 and n=2 is

$\Delta E=-13.6 eV(\frac{1}{1^2}-\frac{1}{2^2})=-13.6 eV(1-\frac{1}{4})=-13.6 eV(\frac{3}{4})=-10.2 eV$

While the difference between the levels n=2 and n=3 is

$\Delta E=-13.6 eV(\frac{1}{2^2}-\frac{1}{3^2})=-13.6 eV(\frac{1}{4}-\frac{1}{9})=-13.6 eV(\frac{5}{36})=-1.9 eV$

And so on.

So, the energy difference between adjacent levels decreases as the quantum number increases.
