a) They are focused into a small area towards the objective lens.
b) They are absorbed by the stage.
c) They are reflected, refracted, or absorbed by the specimen.
d) They are diverted to the ocular lens.
Answer:
C
Explanation:
Ray of light when hits any specimen or object. The light is partially reflected, partially reflected and partially absorbed. It is never completed reflected, refracted or absorbed. Hence, the correct answer would be c.
state Pascal's principle of transmission of pressure
Answer:
Pascal's law (also Pascal's principle or the principle of transmission of fluid-pressure) is a principle in fluid mechanics given by Blaise Pascal that states that a pressure change at any point in a confined incompressible fluid is transmitted throughout the fluid such that the same change occurs everywhere.
Explanation:
Pascal's law says that pressure applied to an enclosed fluid will be transmitted without a change in magnitude to every point of the fluid and to the walls of the container. The pressure at any point in the fluid is equal in all directions.
How much ground do you travel if you travel for 161.65 seconds at a speed of 58.01
Explanation:
Hey there!
Given,
Speed (s)= 58.01m /s
Time (t) = 161.65s
Now, Using distance formula.
[tex]d = s \times t[/tex]
Put all values.
[tex]d = 58.01 \times 161.65[/tex]
Multiply them.
[tex]d = 9377.3166m[/tex]
Therefore the distance is 9377.31m.

A tennis ball is dropped from 1.16 m above the
ground. It rebounds to a height of 0.866 m.
With what velocity does it hit the ground?
The acceleration of gravity is 9.8 m/s
Answer:
Vf = 4.77 m/s
Explanation:
During the downward motion we can easily find the final velocity or the velocity with which the ball hits the ground, by using third equation of motion. The third equation of motion is given as follows:
2gh = Vf² - Vi²
where,
g = acceleration due to gravity = 9.8 m/s²
h = height = 1.16 m
Vf = Final Velocity of Ball = ?
Vi = Initial Velocity of Ball = 0 m/s (Since, ball was initially at rest)
Therefore, using these values in the equation, we get:
(2)(9.8 m/s²)(1.16 m) = Vf² - (0 m/s)²
Vf = √(22.736 m²/s²)
Vf = 4.77 m/s

Why does diffusion happen?
Answer:
Diffusion happens in liquids and gases because their particles move randomly from place to place.
SOMEONE PLEASE HELP!
Answer:
I THINK option A is correct
Explanation:
because the electrostatic force is directly proportional to product of charges
now if the force between two electron is F charge on electron is same so their product is positive now the charge on proton is +ve and on electron is -ve so their product is -F

Claire starts driving with an initial velocity of 5.0 m/s towards north. She drives along a straight, level path with a uniform acceleration and travels 500. M in 20. Seconds. A. What is the average velocity for the entire 20. Seconds? B. What is the velocity at the end of 20. Seconds?
Answer:
A. 25 m/s
B. 100 m/s (i'm not sure about this one)
Explanation:
A. To find average velocity: velocity = distance / time
So it would be V = 500 m / 20 sec = 25 m/s
*This equation can only be used if you are finding velocity for a constant speed or direction or specific distance (in this case it was specific distance).
B. final velocity = initial velocity + acceleration * time
Initial velocity (5.0 m/s) and time (20 sec) is given but not acceleration.
To find acceleration: a = (final velocity - initial velocity) / time
To find final velocity = 5.0 + a * 20
Since there's a missing variable for both equation we will plug the final velocity equation into the acceleration equation so it looks like this :
a = ((5.0 + a * 2.0) - 5.0) / 20
Now solve to get a (acceleration)
Acceleration ends up being 0. So now that we know acceleration we can solve for the final velocity.
final velocity = 5.0 + 0 * 20
= 100 m/s
I know it's a lot but I hope that makes sense! Also for B. I'm not sure if it's right at all but if later I figure out it's wrong I'll edit my answer.

What does acceleration measure
Answer:
Change in velocity
Explanation:
a-p-e-x
Acceleration measures the rate of change of velocity with respect to time. It describes how quickly an object's velocity is changing over time. Acceleration can be positive, negative, or zero. The standard unit for acceleration in the International System of Units (SI) is meters per second squared (m/s²).
Mathematically, acceleration (a) is defined as the change in velocity (Δv) divided by the change in time (Δt):
a = Δv / Δt
Acceleration has both magnitude (how much the velocity changes) and direction. When an object's velocity increases, its acceleration is positive. When the velocity decreases, the acceleration is negative.
The standard unit for acceleration in the International System of Units (SI) is meters per second squared (m/s²), which represents how many meters per second the velocity changes in one second.
However, other units like miles per hour squared (mi/h²) or kilometers per hour squared (km/h²) can also be used depending on the context.

6. Interpret the following graphs and answer the questions below. a Which sounds have a higher frequency than A? b. Which sounds have a lower frequency than A? c. Which sounds all have the same pitch? d. Which sounds are louder than A? e. Which sound has a higher pitch than A, but is at the same volume? f. How would sound D sound compared to A?
Answer:
a) Frequency is inversely proportional to the wavelength, then the graphs with smaller wavelengths than A have larger frequency than A.
The correct options are: B and C.
b) The opposite as above, in this case the correct options are: D and E.
c) The ones with the same wavelength will have the same pitch:
A and F seems to have the same wavelength.
B and C also seems to have the same wavelength.
d) The vertical height of the peaks are related to the louder sounds, then the sounds louder than A are: B and F.
e) The one that has a higher pitch (or smaller wavelength) and the same amplitude than A is C.
(you need to measure the height of the peaks in both graphs, and see that are equal).
f) D has a larger wavelength than A, so it would sound "lower", and both waves have the same amplitude, so the loudness will be the same.
Scientists might model volcanic eruptions using a computer model. What is
the biggest benefit of this model?
Scientific model of volcanic eruptions using computer programming is very helpful to identify their origin and consequences. The biggest benefit of these model is to identify the physical behaviors of magma .
What are scientific models ?Scientific model are used to visualize the complex theories and concepts. There are both theoretical models and visual models. Nowadays complex problems and processes are easily solving using well designed computer programmes and simulations.
By creating a sophisticated computer model based on the most recent physical understanding of magma behavior, its most likely path of least resistance, and statistical information obtained from prior volcanic eruptions, scientists was able to address these issues.
They were able to predict the site of historical events that were not used to fine-tune the model by using historical data collected from Campi Flegrei, a caldera close to Naples, Italy etc.
