What is the frequency between two turning forks if one has a frequency of 520 Hz and 528 Hz?

Answers

Answer 1

Answer:

Answer:

Two tunnig fork of frequency 520 Hz and 524Hz are vibrated together. It means beats form due to it .

f₁ = 524 Hz

f₂ = 520 Hz

Beat period = 1/number of Bea are formed per unit time

= 1/(f₁ - f₂)

= 1/(524 - 520)

= 1/4 sec

Now, time inveral between successive maximum and minimum intensities = beat period= 1/4 sec

In nuclear physics, what units are used to measure the radius of an atom? A. liters B. mililiters C. fermi D. grams?

Answers

It's quite easy to get the answer. Think about it: liters and mililiters both are measure of volume - withdraw, grams are used to measure mass.
The one remained is C. fermi( femtometer) which is obviously correct answer.

What is the correct formula for work?a. Work = force / time
b. Work = force * distance
c. Work = force / distance
d. Work = mass * acceleration

Answers

The correct formulafor work is option B. Work = force * distance.

What is Work and what is its formula?

In physics, the term "work" has a specific meaning.
Work, in physics, occurs when a force acts on an object to move it some distance from the start point (also called displacement).
Work is calculated as the force times the distance.
In other words, work is equivalent to the application of a force over a distance.
The amount of work a force does is directly proportional to how far that force moves an object.
The work formula is w = F × d.
F is the force, d is the distance, and w is the work.

A star's apparent magnitude is most closely related to which of the following? Select all that apply.a. radius.
b. luminosity.
c. distance from Earth.
d. absolute magnitude. E. surface temperature.

Answers

Answer:

Luminosity

Explanation:

The apparent magnitude is a measure of the star's apparent luminosity, the apparent luminosity is directly related to the star's apparent magnitude.

The star's luminosity is the measure of the star's brightness and this diminishes with distance, the luminosity of a star also depends on the size of the star, this means that a star's magnitude and luminosity are directly related.

If you want the "most", then you can't have more than one.

A star's apparent magnitude is determined by both its intrinsic luminosity
and its distance from us.

A scientist told his student assistants that he had sorted groups of mice by their intelligence and asked the assistants to assess the groups’ maze-solving abilities. The scientist had not actually sorted the mice by intelligence. The students rated the “highest intelligence” group of mice as the best maze solvers and the “lowest intelligence” group as the worst maze solvers. What was the scientist trying to demonstrate by doing this experiment?Experimental subjects should never be put into groups.
Mice should not be judged by their intelligence.
Higher intelligence mice are better maze solvers.

What is the process by which water dissolves certain minerals in the soil and carries them away?

Answers

The correct answer would be LEACHING. When at first thought, it would seem that it is erosion. Erosion not only eliminates the soil minerals, it also washes everything else and that includes the soil. In a different manner, Leaching can happen when certain minute particles of the minerals are melted and mixes with water. All that is left in the soil will be the bigger particles that are not soluble by water. In this manner, only a soil that cannot properly nourish remains as it is stripped off of minerals.
