What is observed when a noble gas is heated and the emitted light shone through a prism?.

Answers

Answer 1

Given what we know, we can confirm that when a noble gas is heated and the emitted light is shone through a prism, we can observe the emission spectrum.

What is the emission spectrum?

These can be described as lines of different colored lights. These lines will be the observed results after heating the gas and shining its light through a prism. This emission spectrum can provide important information regarding the chemical composition of its source.


Therefore, we can confirm that the emission spectrum, described as lines of varying colors, is what we observe when a noble gas is heated and the emitted light is shone through a prism.

Susan works in the research and development department. She has recently purchased a large high-speed external drive and has attached the drive to her computer using a USB cable. Her drive requires a minimum bandwidth of 400 Mbps and at least 900 milliamps (mA) to function.
Although the correct drivers are installed, the drive is not functioning. To troubleshoot the problem, she has connected her drive to her coworkers' computer where the drive functions properly. No additional cables are required for this drive.
Which of the following is the MOST likely reason Susan's external hard drive is not working?
A. Susan has connected her drive to a USB 3.0 port, which does not have enough power for her drive.
B. Susan has connected her drive to a USB 2.0 port, which does not have enough power for her drive.
C. Susan has connected her drive to a USB 3.0 port, which does not support the maximum bandwidth required.
D. Susan has connected her drive to a USB 2.0 port, which does not support the maximum bandwidth required.

Answers

Susan has connected her drive to a USB 2.0 port, which does not support the maximum bandwidth required. The correct option is D.

Thus, The issue is probably related to the USB port's bandwidth because the disc works perfectly on her coworker's PC and the right drivers are loaded.

The drive requires a minimum bandwidth of 400 Mbps, and USB 2.0 ports often have less bandwidth than USB 3.0 ones.

As a result, using a USB 2.0 connector to connect the drive might not give it enough bandwidth to operate as intended.

Thus, Susan has connected her drive to a USB 2.0 port, which does not support the maximum bandwidth required. The correct option is D.

Two trains leave a station at the same time, Train A travels at a constant speed of 16 m/s. Train B starts at 8.0 m/s but accelerates constantly at 1.0 m/s squared. After 10.0 seconds, which train has the greater speed?

Answers

Answer:

Train B

Explanation:

train a is traveling at 16m/s no matter what time since it's a constant

to find final velocity of train B we use

v2=v1 +at

v1 = 8m/s

a = 1m/s squared

t = 10 s

v2 = 8 + 1(10)

v2 = 18

train B travelling at 18 m/s at 10 secs

What is the thermodynamic equilibrium?

A system in equilibrium if it is not able to experience spontaneous changes.

Here, we assume that our system is just the two objects with the given temperatures, and nothing else.

Thus, when we put them together, the only thing that will happen is a heat transfer (from the hotter object to the other one), until both of them have the same temperature (when both objects have the same temperature the heat flux stops).

Also, the object with temperature 2*T loses temperature, while the object with temperature T increases its temperature, then we can conclude that the final temperature of both objects will be in between these:

T < Tₓ < 2*T

To get the exact final temperature, we would need more information.

So what will be true after some time has passed?

A ball accelerates from rest down a ramp at 2.4 m/s^2. Write an equation that could be used to determine the balls finals position, assuming the positive direction points down the ramp.

Answers

Answer:

x=2.4t+4.9t^2

Explanation:

This equation is one of the kinematic equations to solve for distance. The original equation is as follows:

X=Xo+Vt+1/2at^2

We know that the ball starts at rest meaning that its initial velocity and position is zero.

X=0+Vt+1/2at^2

Since it is going down the ramp, you can use the acceleration of gravity constant. (9.81 m/s^2) and simplify that with the 1/2.

X=Vt+4.9t^2

Note: Since the positive direction in this problem is down, you are adding the 4.9t^2, but if a question says that the downward direction is negative, you would subtract those values.

Now, substitute in your velocity value.

X=2.4t+4.9t^2

A student is standing 8 m from a roaring truck engine that is measured at 20. The student moves 4 m closer to the engine. What is the measured sound intensity at the new distance?.

Answers

By knowing how intensity relates to distance, we will see that at 4 meters of the engine the intensity is 80.

How sound intensity relates to distance?

The sound spreads in a solid angle like all waves, so the intensity of the sound will decrease with the distance squared, this means that:

[tex]I = \frac{P}{4*pi*r^2}[/tex]

Where P is the sound power, we know that when the student is at 8m from the engine, the intensity measured is 20 (it does not tell the units) so we have:

[tex]20 = \frac{P}{4*3.14*(8m)^2} \\\\P = 20*4*3.14*(8m)^2 = 16,078.8 m^2[/tex]

Now, if you move 4 meters closer to the engine, your new position will be:

r = 4m

Then we have:

[tex]I = \frac{16,078.8 m^2}{4*3.14*(4m)^2} = 80[/tex]

A solid sphere rolls along a horizontal, smooth surface at a constant linear speed without slipping. What is the ratio between the rotational kinetic energy about the center of the sphere and the sphere’s total kinetic energy?.

Answers

The ratio of the rotational kinetic energy about the center of the sphere and the total kinetic energy of the sphere is 2/7.

What is the rotational kinetic energy of a sphere?

The rotational kinetic energy of the sphere is directly proportional to the square of angular acceleration.

[tex]K = \dfrac 12 I\omega ^2[/tex]

Where,

[tex]I[/tex] = rotational inertia of sphere = 2/5MR²

Where [tex]M[/tex] is the mass of the sphere and [tex]R[/tex] is the radius of the sphere,

ω = angular acceleration of sphere = V/R

Where [tex]V[/tex] is the speed of the sphere.

So,

K = 1/2 × 2/5MR² × V²/R²

K = MV²/5

The translational kinetic energy of the sphere,

[tex]K' = \dfrac 12 MV^2[/tex]

The total kinetic energy of the sphere,

[tex]K_t = K + K'[/tex]

So,

[tex]K_t= \dfrac {MV^2}5 +\dfrac { MV^2}2\\\\K_t= \dfrac {7MV^2}{10}[/tex]

Thus the Ratio of rotational kinetic energy to total kinetic energy,

[tex]\dfrac KK_t = \dfrac {\dfrac {MV^2}{5} }{ \dfrac {7MV^2}{10}}\\\\\dfrac KK_t = \dfrac 15 \times \dfrac { 10}7\\\\\dfrac KK_t= \dfrac 27[/tex]

Therefore, the ratio of the rotational kinetic energy about the center of the sphere and the total kinetic energy of the sphere is 2/7.

R = 6 ohms

Now, formula for sum of resistance in parallel is;

1/R = 1/R1 + 1/R2 + 1/R3 ....

Since we have four of the resistor combination above in parallel, then;
