Answer:

I don't really understand the numbers that you presented, but ill try to answer the question.

Jay is taking data on the weight of a basket with eggs depending on the number of eggs that is in the basket.

So for 1 egg, he knows that the basket weights w1

for 2 eggs he knows that the basket weights w2

and so on.

Then, in this context, if he does a linear relation of:

Weight = number of egs*k + b

where k is the slope and b is the y-intercept.

k represents the average weight of one egg, and b is the initial weight of the basket.

san4es73 [151]

Answer:

0.87 m

70.6 Hz

Explanation:

$L$ = length of the rope = 1.30 m

$n$ = order of the harmonic = 3

$\lambda$ = Wavelength

Wavelength is given as

$\lambda = \frac{2L}{n}$

$\lambda = \frac{2(1.30)}{3}$

$\lambda$ = 0.87 m

$v$ = Speed of transverse wave = 61.4 m/s

$f$ = frequency of the third harmonic

frequency is given as

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

$f = \frac{61.4}{0.87}$

$f$ = 70.6 Hz

While no one knows why, astronomers do now know that the solar nebula has ___________?

iris [78.8K]

While no one knows why, astronomers do now know that the solar nebula has collapsed. Scientists believed that our Solar system was made when gas and dust cloud was being disturbed by an explosion of supernova. Due to pressure, this cloud collapsed.

A string of length L, mass per unit length \mu, and tension T is vibrating at its fundamental frequency. What effect will the fo

viva [34]

The fundamental frequency on a vibrating string is given by:

$f=\frac{1}{2L}\sqrt{\frac{T}{\mu}}$

where

L is the length of the string

T is the tension

$\mu$ is the mass per unit length of the string

Keeping this equation in mind, we can now answer the various parts of the question:

(a) The fundamental frequency will halve

In this case, the length of the string is doubled:

L' = 2L

Substituting into the expression of the fundamental frequency, we find the new frequency:

$f'=\frac{1}{2(2L)}\sqrt{\frac{T}{\mu}}=\frac{1}{2}(\frac{1}{2L}\sqrt{\frac{T}{\mu}})=\frac{f}{2}$

So, the fundamental frequency will halve.

(b) the fundamental frequency will decrease by a factor $\sqrt{2}$

In this case, the mass per unit length is doubled:

$\mu'=2\mu$

Substituting into the expression of the fundamental frequency, we find the new frequency:

$f'=\frac{1}{2L}\sqrt{\frac{T}{2 \mu}}=\frac{1}{\sqrt{2}}(\frac{1}{2L}\sqrt{\frac{T}{\mu}})=\frac{f}{\sqrt{2}}$

So, the fundamental frequency will decrease by a factor $\sqrt{2}$ .

(c) the fundamental frequency will increase by a factor $\sqrt{2}$

In this case, the tension is doubled:

$T'=2T$

Substituting into the expression of the fundamental frequency, we find the new frequency:

$f'=\frac{1}{2L}\sqrt{\frac{2T}{\mu}}=\sqrt{2}(\frac{1}{2L}\sqrt{\frac{T}{\mu}})=\sqrt{2}f$

So, the fundamental frequency will increase by a factor $\sqrt{2}$ .

Which of the following values represents an index of refraction of an actual material?

serg [7]

Sadly, we're forced to answer the question without the benefit of the
list of choices, which, for some reason, you decided not to let us see.

Index of refraction of a substance =

(speed of light in vacuum) / (speed of light in the substance).

Any number greater than ' 1 ' can be an index of refraction. A number
less than ' 1 ' can't be . . . that would be saying that the speed of light
in this substance is greater than the speed of light in vacuum.

Why is it important that we learn about our solar system, the sun, and planets in our solar system other than Earth?

tangare [24]

Answer:

To understand all the different kind of elements and how they work. Nature is a beautiful thing and it is important we understand how they survive and how we can help. The solar system is a mandatory nature. Learning about other planets also helps us feel safe and more knowledgable.
