In any given wave, when the frequency of the wave doubles (f = 2f), which of the following other changes would also take place?
Zanzabum

Answer:

The correct answer is -

B. The velocity would double (v = 2v).

C. The wavelength would be half (λ = λ/2).

Explanation:

A wave has a speed or velocity that is related to the wavelength of the wave and the frequency of the wave and this relationship can be represented by the following equation-

Wave velocity V = Wavelength (λ) * Frequency (f)

Frequency (f) = Velocity (V) / Wavelength(λ).

The frequency and wavelength are inversely proportional and frequency and velocity are directly proportional to each other.

So, if f = 2f then,

putting value in the formula,

2f = 2v/λ, which means, f = 2v and f = λ/2

when the frequency is doubled, the wavelength will be halved and velocity will be doubled.

Which of the following statements are true?a. Earth's geographic south pole is also a magnetic south pole. b. Scientists have ev
ANTONII [103]

Answer:

c, d, and f.

Explanation:

Let us look at each of the statements one at a time:

a. Earth's geographic south pole is also a magnetic south pole.

This is not true. Earths magnetic south pole is slightly off (2,860 km away) from earth's geographical south pole.

b. Scientists have evidence that single isolated magnetic poles, called magnetic monopoles, exist.

Nope. So far no evidence yet exists that hypothetical magnetic monopoles exist.

c. The north pole of a bar magnet will attract the south pole of another bar magnet.

True, since opposite ends of a magnet attract and like ends repel.

d. The south poles of two bar magnets will repel each other.

Also true since like poles of a magnetic repel each other.

e. The north poles of two bar magnets will attract each other.

No, the north poles of two magnets will repel each other since they have the same polarity.

f. Earth's geographic north pole is actually a magnetic south pole.

Yes. If you call the point of the needle that points north the north pole of the compass,<em> then it points north because it is attracted to the south pole of earth's magnetic field.</em> (like repel opposites attract)

Which statement best describes how scientists and engineers work together
alexandr402 [8]

Answer:

Option D: Engineers come up with scientific questions when they are

developing their design, and scientists do research to answer

them.

Explanation:

Normally, scientists work involves study of how nature works while engineers work is to create new things, such as websites, products e.t.c. Now, the objectives of engineers and scientists are different because they follow different processes while working to achieve their results. Scientists perform experiments using the scientific method which involves processes such as constructing hypothesis and testing with an experiment while, engineers usually follow the creativity based design engineering processes which involves developing of prototype solutions and testing those solutions.

Thus, it's clear that engineers deal with design while scientists deal with research.

The correct answer will be option D
