Answer:

the ratio of marginal benefits to price should be identical across all goods.

Explanation:

In equilibrium, the ratio of marginal benefits to price should be identical across all goods.

marginal benefit is the the maximum amount of money a customer is willing to pay for an additional good or service. The consumer satisfaction tend to decrease as the consumption increases. And for equilibrium to exist  the ratio of marginal benefits to price should be identical across all goods

You are watching an archery tournament when you start wondering how fast an arrow is shot from the bow. Remembering your physics
lianna [129]
<h2>Answer:</h2>

<em><u>Velocity of throwing arrow = 43.13 m/s.</u></em>

<h2>Explanation:</h2>

In the question,

Let us say the height from which the arrow was shot = h

Distance traveled by the arrow in horizontal = 61 m

Angle made by the arrow with the ground = 2°

So,

From the <u>equations of the motion</u>,

61 =u.t\\t=\frac{61}{u}

Now,

Also,

Finally, the angle made is 2 degrees with the horizontal.

So,

Final horizontal velocity = v.cos20°

Final vertical velocity = v.sin20°

Now,

u = v.cos20° (No acceleration in horizontal)

Also,

v=u+at\\vsin20=0+9.8(t)\\t=\frac{v.sin20}{9.8}

So,

We can say that,

\frac{v.sin20}{9.8}=\frac{61}{v.cos20}\\v^{2}.sin20.cos20=597.8\\v^{2}=1860.56\\v=43.13\,m/s

<em><u>Therefore, the velocity with which the arrow was shot by the archer is 43.13 m/s.</u></em>

A pure sound wave, generated by a tuning fork, is considered a periodic wave. Which statement is true for this tuning fork sound
soldier1979 [14.2K]

Answer : Every wave has the same wave pattern.

Explanation : A pure sound wave has a single frequency and its generated by a tuning fork . The sound wave is a  simple periodic wave.

When an object such as a guitar push and pull on the around it. When it pushes on the air, then the pressure increases and when it pull on the air,  then the pressure decreases and sound waves are formed.

Hence, sound wave has the same wave pattern.

All of the following are physical proporties of chlorine EXCEPT it ___
ss7ja [257]

Answer:

Option D

Reacts with sodium to form chloride

Explanation:

First, reaction between chlorine and sodium is a chemical reaction and not physical properties. Secondly, when chlorine reacts with sodium, it forms sodium chloride, NaCl NOT chloride as depicted by the statement. Otherwise, chlorine exists in the form of gas and is yellowish in color. Moreover, it's density is approximately 3.11 grams per liter. Therefore, the right answer is option D

Which value is represented by the slope of the line?
netineya [11]

The slope of the line is

(change in ' y ' between the ends)  /  (change in ' x ' between the ends)

Slope = (630g - 0) / (70 cm^3 - 0)

Slope = (630 / 70) g/cm^3

<em>Slope =  9.0 g/cm^3</em>
