1. Explain how fluid B is different from fluid A

if all three fluids were placed together in a jar, which one would float on top explain?

Answer:

Fluid B is different from fluid A in its density.

Explanation:

As you can see in the mass-Volume graph. The ratio of mass to volume of fluid A is more than that of fluid B.

Density = mass/volume

If all three fluids were placed together in a jar, the one with lowest density will float on top. It means that fluid C will float on top as it has the lowest mass/volume ratio.

2. if each fluid was put into a different cup of the same size, which one would have the most mass explain?

Answer:

Fluid A will have the most mass.

Explanation:

All three fluids have different density. When placed in different cups of same size, we will have equal volume of each of the fluid.

Now that Volume is constant.

Density = mass/Volume

⇒Mass ∝ Density

The most denser fluid will have the most mass.

The answer is fluid A.

3. if you measured 20 g of each liquid, which one would take up the least amount of space explain.

Answer:

Fluid A would take up the least amount of space.

Explanation:

All three fluids have different mass to volume ratio. In this case, 20 g of each fluid is taken. It means that mass becomes constant.

So Density = Mass/Volume

⇒ Density ∝ 1/volume

Volume is inversely proportional to the density of the fluid.

Hence, Fluid with highest density will have the minimum volume.

The answer is fluid A.

A toy car has a 1.5-A current, and its resistance is 2 . How much voltage does the car require?

oee [108]

Voltage = (current) x (resistance)

Voltage = (1.5 A) x (2 ohms)

In order to MAKE 1.5 A of current flow through the toy car, you have to PROVIDE <em>3 volts</em> from the battery.

. Inside a laser apparatus, the stimulation and relaxation of electrons in atoms causes many photons with the same to be continu

mrs_skeptik [129]

Inside a laser apparatus, the stimulation and relaxation of electrons in atoms cause many photons with the same <u>wavelength </u>to be continuously emitted.

From the questions given, the main objective is to fill in the gaps and add important information where necessary. The missing information is highlighted in bold and underlined.

Inside a laser apparatus, the stimulation and relaxation of electrons in atoms cause many photons with the same <u>wavelength </u>to be continuously emitted.

2. When these photons are emitted, they travel between two <u>reflective </u>

surfaces to form the wave that is represented in the simulation.

3. This wave is the summation of all the photons being introduced with

every oscillation, and as they continue to travel, the amplitude

<u>increases. </u>

4. This occurs because the photons are emitted in a coherent fashion;

however, amplitude when the photons overlap in an incoherent

fashion.

5. In a laser device, a small portion of photons are permitted to escape

(for use in an application). This is emulated in the simulation, by

settling the Damping to Lots such that amplitude <u>remains relatively </u>

<u>constant </u>when compared to damping of None. (Damping

represents the Loss of photons.

6. The generation of multiple wavelengths is possible in some laser

producing systems, and the diffraction angle can be <u>varied</u> to allow

the isolation of different wavelengths.

7. Finally, when the power of a laser is described, the wave property

that is being referenced is a function of its frequency and

<u>amplitude.</u>

Therefore, we can conclude that we've fully understood the concept of emission of photons and wavelength in a laser apparatus.

A physicist drives through a stop light. When he is pulled over, he tells the police officer that the Doppler shift made the red

makkiz [27]

Answer:

Explanation:

$\lambda$ = Observed wavelength = 550 nm

$\lambda'$ = Actual wavelength = 635 nm

c = Speed of light = $3\times 10^8\ \text{m/s}$

v = Velocity of the physicist

Doppler shift is given by

$f=\sqrt{\dfrac{c+v}{c-v}}f'\\\Rightarrow \dfrac{c}{\lambda}=\sqrt{\dfrac{c+v}{c-v}}\dfrac{c}{\lambda'}\\\Rightarrow \dfrac{\lambda'^2}{\lambda^2}=\dfrac{c+v}{c-v}\\\Rightarrow \dfrac{\lambda'^2}{\lambda^2}=\dfrac{1+\dfrac{v}{c}}{1-\dfrac{v}{c}}\\\Rightarrow \dfrac{\lambda'^2}{\lambda^2}(1-\dfrac{v}{c})=1+\dfrac{v}{c}\\\Rightarrow \dfrac{\lambda'^2}{\lambda^2}(1-\dfrac{v}{c})=1+\dfrac{v}{c}\\\Rightarrow \dfrac{\lambda'^2}{\lambda^2}-1=\dfrac{v}{c}(1+\dfrac{\lambda'^2}{\lambda^2})\\\Rightarrow v=\dfrac{c(\dfrac{\lambda'^2}{\lambda^2}-1)}{1+\dfrac{\lambda'^2}{\lambda^2}}$

$\Rightarrow v=\dfrac{3\times 10^8\times (\dfrac{635^2}{550^2}-1)}{1+\dfrac{635^2}{550^2}}\\\Rightarrow v=42817669.77\ \text{m/s}$

The physicist was traveling at a velocity of $42817669.77\ \text{m/s}$ .

light inside the thin glass tube of a laparoscopic surgical device strikes the edge of the glass tube and is entirely reflected

vovangra [49]

Light striking the walls of the glass cylinder and reflecting in inside tube itself is a phenomenon known as total internal reflection.

<h3>What word best describes reflection, in your opinion?</h3>

Reflection is often synonymous with the verbs cogitate, contemplate, reason, hypothesize, and think. All of these expressions mean "using one's intellect, judgment, or inference faculties," but the word "reflect" means carefully considering a recollection.

<h3>What does it mean to give reflection some thought?</h3>

constant verb When you ruminate, you seriously consider something. Alternatives include thinking, analyzing, planning, and thinking. More phrases containing "reflect" Reflecting feelings is the act of observing a person's verbal and nonverbal signs for their emotions and feelings, then immediately communicating (or reflecting) those attitudes to the user or customer.
