The size is also different is the correct alternative for the bolded phrase 'distinguish the sizes' that made it feasible for the astronomers to see the stars. Hence option a is the answer.
What tools did astronomers employ in order to gauge the star's temperature?Our night sky is gradually becoming less visible as a result of all the lamps, spotlights, and building lights combined. The sky will only get darker to a gray color with increased light pollution, making the night appear less pitch-black and obscuring the stars. By observing the star's color and spectrum, astronomers can determine the temperature of the star.
How bright we perceive a star is indicated by its apparent brightness. A star's luminosity provides information about its actual brightness.

Technician A says crankshafts are internally balanced using counterweights. Technician B says crankshafts are externally balanced using counterweights. Who is correct?
Answers
Technician A is correct because he sayss crankshafts are internally balanced using counterweights.
Are crankshafts internally or externally balanced using counterweights?Counterweights are strategically placed on the crankshaft to offset the reciprocating forces generated by the piston and connecting rod assembly. These counterweights are designed to counterbalance the mass of the piston and connecting rod, reducing vibrations and ensuring smooth operation of the engine.
Internal balancing means that the counterweights are located within the crankshaft itself, positioned to balance the rotating assembly while external balancing involves adding additional weights outside of the crankshaft, such as on the flywheel or harmonic balancer, to achieve balance.

O 0.1049
O 0.3694
O 0.4744
O 0.5256
O 0.8951
Answers
The z-score of the given values are a measure of how many standard
deviations are between the given value and the mean.
The proportion of students that own between 20 and 30 pairs of shoes is
0.5256
Reasons:
The mean score, \(\bar{x}\) = 22.1
Standard deviation of the sample, s = 6.3
The range of the shoe size = Between 20 and 30
The z-score, is given as follows;
\(Z= \mathbf{\dfrac{x-\mu }{\sigma }}\)
The z-score of 30 is given as follows;
\(Z=\dfrac{30-22.1 }{6.3 } \approx 1.254\)
The probability from the z-table is, P(x < 30) = 0.89507
The z-score of 20 is given as follows;
\(Z=\dfrac{20-22.1 }{6.3 } \approx -0.333\)Therefore, from the z-table, we have;
P(x < 20) = 0.36944
∴ The difference P(20 < x < 30) = 0.89507 - 0.36944 = 0.52563
P(20 < x < 30) ≈ 0.5256
The proportion of students that own between 20 and 30 pairs of shoes is
0.5256.

The position function of a car moving along a mountain road is given by the function f(t) = t^3 - 2t^2 + 4 kilometers, where t is in hours. What is the instantaneous velocity of the car at t = 2 hours?
Answers
Answer: 4 Kilometers per hour.
Explanation: The instantaneous velocity of the car at t = 2 hours can be found by taking the first derivative of the position function. The derivative of f(t) = t^3 - 2t^2 + 4 is f'(t) = 3t^2 - 4t.
Substituting t = 2 into the derivative function gives us:
f'(2) = 3 * 2^2 - 4 * 2 = 12 - 8 = 4
So, the instantaneous velocity of the car at t = 2 hours is 4 kilometers per hour.

Estuary provides refuge after dam removal for bull trout
Bull trout use a bewildering array of strategies to aid in their survival, from remaining in streams their whole lives, like rainbow trout, to spending part of their lives in the ocean before returning to
streams to spawn, just as salmon do.
Bull trout are present in only one of two neighboring rivers in the Olympic peninsula, Washington state, and in this one (the Elwha River), where two large dams were removed. Dam removal resulted
in massive outflow of sediments, reducing the clarity of the water and also building up a large delta and expanding the size of the estuary at the mouth of the Elwha River.
Sampling for bull trout before, during, and after dam removal was used to detect whether bull trout changed their use of the Elwha River estuary or moved into the adjacent Salt Creek stream where
they were formerly absent. Sampling revealed no movement into Salt Creek, but numbers of bull trout in the Elwha River estuary increased greatly during and immediately after dam removal,
coinciding with large sediment outflow, before returning to their original low levels. Thus, bull trout appear to have used the enlarged estuary as a refuge from the effects of dam removal, then
returning to the river when the river water cleared up from the sediment
Of additional interest is the long-term response of bull trout to the additional habitat opened up above the former dams.

Some forested areas of the country have large, flat-topped boulders left behind by glaciers.
The tops of the boulders have become covered with lichens, grasses, shrubs,
and even some small trees. Deer can jump onto the top of shorter boulders to graze; however, none
of the deer can jump onto the tallest boulders. Scientists sampled vegetation from the tops
of these boulders, some of which were grazed by deer and some of which were not.
Scientists observed that the most diverse plant growth occurred on the boulders that could
not be reached by deer.
(e) Identify the control group for the investigation.
(f) Identify the hypothesis for the investigation
Answers
Glaciers often exhibit downward movement in the sloppy areas, as glacial retreat. The forested areas in the vicinity of the glaciers would be present at various altitude levels as well as a variety of climatic factors, especially, having different sets of temperature, humidity, precipitation, etc.
What did the investigations revealed?Now, the investigation reveals that the movement of glaciers had left behind several flat-topped boulders, which have their flat top surfaces covered with vegetation such as, shrubs, lichen, grasses as well as small trees. Some of these boulders have been reached by the deer for grazing purposes, while few tallest boulders couldn’t be reached by them.
Sampling of the vegetation at both type of boulders by the scientists has revealed that the tallest boulders, which have not been grazed by the deer possessed a diverse vegetation in comparison to those boulders, which have been grazed.
The dependent variables in this study are the factors such as, altitude at which the boulders are situated in the forested areas, climatic factors such as, humidity, precipitation and temperature at different altitudes at which boulders are situated as well as preferred vegetation by the deer for grazing in the accessible boulders.
The most significant variable, which is not mentioned in the investigation is the altitude at which different boulders have been studied in the forested areas. As, the altitude exerts substantial influence on the type of vegetation occurring. It could affect the results, as different altitudes exhibit different vegetation.
Other significant factors are the climatic factors such as temperature, precipitation and humidity of the location at which different boulders have been studied.
When the glaciers move, they exhibit the process of weathering of the rocks and surface coming in their way. They take with them boulders, smaller rocks, mud particles, and deposit it somewhere in their downward course, while moving gradually. These deposited mud particles, smaller rocks and boulders then contribute in the soil formation.
The agents of weathering such as, wind, water, temperature, etc., subject the smaller rocks and boulders to weathering mechanism and led to their fragmentation. Further, the weathered rock particles along with deposited mud particles from the glaciers resulted in the formation of soil.
Anthropogenic occurrences or factors such as logging of forests, use of forested lands for herbs and crop production, accessing the forested areas for recreational and leisure purposes contribute to the weathering process and thus, affects or contribute in the soil formation in the forested lands.

Johnny was miserable. It was Saturday afternoon, the sun was shining brightly, and he was stuck in bed with the flu. His throat felt like sandpaper every time he swallowed, his head felt as if someone had dropped an anvil on it, and he couldn’t stop coughing. His mother had checked his temperature earlier in the day and announced that he was too sick to get out of bed, let alone go outside to enjoy the first warm spring day along with his friends and siblings. From his room, Johnny could hear his sisters’ high-pitched squeals of delight and the ringing of their bicycle bells as they rode up and down the sidewalk. He could hear someone bouncing a basketball and the swoop of the ball as it swished through the net. He also heard his best friend, Noah, asking where Johnny was and his sisters’ reply that he couldn’t come out to play because he was sick. This was too much. Johnny pulled the soft, velvety covers over his aching head and turned to the wall in protest, realizing there was nothing he could do but wait for this virus to take its course. He swore to himself that he would be better by next Saturday and that he would be outside riding his bike and shooting baskets along with everyone else.

Determine the value of the annuity for the indicated monthly deposit amount, the number of deposits, and the interest rate. You will need to determine the value for r to solve this problem. When finding r round it to the nearest ten thousandths. Deposit amount: $150; total deposits: 24; interest rate: 3%, compound monthly. The value for r is:____ The value of the annuity is $____
Answers
Answer: To find the value of the annuity for the indicated monthly deposit amount, number of deposits, and interest rate, we can use the following formula:
```A = PMT * ((1 + r/n)^(nt) - 1) / (r/n)```
Where:
- A is the value of the annuity
- PMT is the monthly deposit amount
- r is the interest rate
- n is the number of compounding periods per year
- t is the total number of years
In this case, the values are:
- PMT = $150 (monthly deposit amount)
- r = 0.03 (interest rate)
- n = 12 (compounding periods per year)
- t = 24/12 = 2 (total number of years)
Substituting these values into the formula above, we get:
```A = $150 * ((1 + 0.03/12)^(12*2) - 1) / (0.03/12)```
Simplifying this expression gives us:
```A = $150 * (1.0275^24 - 1) / 0.0025```
Evaluating this gives us:
```A = $3,789.09```
Therefore, the value of the annuity is $3,789.09.
To find the value of r, we can rearrange the formula above and solve for r:
```r = n * (((A * (r/n)) / PMT) + 1)^(1/(n*t)) - n```
Substituting the values we have, we get:
```0.03 = 12 * (((3789.09 * (0.03/12)) / 150) + 1)^(1/(12*2)) - 12```
Solving this equation gives us:
```r = 0.0330```
Rounding to the nearest ten thousandths as requested, the value of r is 0.0330.
