When climbing a steep hill, would you want a larger or smaller bicycle gear?

Answers

Answer 1

Answer:

Answer:

Usually when climbing, it's best to be in the small front ring and the largest back ring. If your cadence is about 100 rpm, then whatever gear you're in is fine. It depends on the road, but as long as your pedaling is at a level you're comfortable with, you're fine.

Answers

The answer that best describes how DNA is used as a molecular clock is the number of mutations in DNA is compared between two species.

Answer:

The correct answer is a = The number of mutations in DNA is compared between two species.

Explanation:

Hello ! Let's solve this!

The molecular clock is a technique to see the divergence between two species. In other words, to see DNA mutations.

The correct answer is a = The number of mutations in DNA is compared between two species.

Two musicians are comparing their trombones. The first produces a tone that is known to be 438 Hz. When the two trombones play together they produce 6 beats every 2 seconds. Which statement is true about the second trombone? It is producing a 444-Hz sound, and could be producing no other sound frequency. It is producing either a 436-Hz sound or a 440-Hz sound. It is producing either a 435-Hz sound or a 441-Hz sound. It is producing either a 432-Hz sound or a 444-Hz sound. It is producing a 441-Hz sound, and could be producing no other sound frequency.

Answers

Answer:

It is producing either a 435-Hz sound or a 441-Hz sound.

Explanation:

When two sound of slightly different frequencies interfere constructively with each other, the resultant wave has a frequency (called beat frequency) which is equal to the absolute value of the difference between the individual frequencies:

$f_B = |f_1 -f_2|$ (1)

In this problem, we know that:

- The frequency of the first trombone is $f_1 = 438 Hz$

- 6 beats are heard every 2 seconds, so the beat frequency is

$f_B=(6)/(2 s)=3 Hz$

If we insert this data into eq.(1), we have two possible solutions for the frequency of the second trombone:

$f_2 = f_1 - f_B = 438 Hz - 3 Hz = 435 Hz\nf_2 = f_1+f_B = 438 Hz+3 Hz=441 Hz$

Which event can be excluded from a list of interactions among Earth's spheres?A solar flares
B volcanic eruption
C fracking for natural gas
D hurricane

Answers

Final answer:

Solar flares can be excluded from a list of interactions among Earth's spheres because they are not directly related to interactions among the geosphere, hydrosphere, atmosphere, and biosphere.

Explanation:

The event that can be excluded from a list of interactions among Earth's spheres is A solar flares. Solar flares are not directly related to interactions among Earth's spheres, which include the geosphere, hydrosphere, atmosphere, and biosphere.

On the other hand, volcanic eruptions, fracking for natural gas, and hurricanes are all examples of interactions among Earth's spheres. Volcanic eruptions involve the release of gases and materials from the geosphere into the atmosphere. Fracking for natural gas involves extracting resources from the geosphere and potentially impacting the hydrosphere. Hurricanes involve interactions between the atmosphere and the hydrosphere, resulting in powerful storms.

Therefore, the correct answer is A solar flares.
