7. A very wealthy donor decides to give a large sum of money to your college or university to build the world's largest visible-

light gathering telescope. From an astronomical perspective, where would be the best location to put such a telescope? a. in a dark spot right on the campus b. on the west coast of the U.S. very close to sea level (a location like Seattle, for example) c. close to a large city where there are many astronomers to use it d. on a tall, dry mountain peak e. Bayonne, New Jersey

Answer:

the correct answer is d

on a tall, dry mountain peak

Explanation:

A telescope is an instrument that allows the observation of distant bodies whose light is very dim, for this the telescope concentrates a large amount of light with large diameter lenses or mirrors.

The location of a telescope must take into account several aspects:

* The most important that there are no nearby lights that disturb the observation, so it must be away from cities and other strong light sources.

* The climate should be as stable as possible with few temperature variations, to prevent the optical surfaces from fogging up and reducing the thermal expansion that changes the length of the instrument.

* You must choose a place with little rain and therefore little amount of clouds

Based on these needs we can answer which luxury will be the most suitable

a) There is a lot of light nearby

b) there is a lot of humidity and wind

c) there is a lot of light

d) This is an ideal place with low light, low humidity and stability in the climate

e) lots of humidity and light

so the correct answer is d

I need help on ideas for a science project.. (highschool ideas)
Nana76 [90]

A research question that would complete the third question you need that are related to the first 2 questions which are:

  • “what type of masks help prevent fog on glasses when breathing?”
  • “does a mask’s material affect the level of fog on glasses as an effect of breathing?”

Would be: "Are there any available masks that could prevent fog on glasses that could be improved upon"?

This new research question would help you find out if there is an already existing mask that could be made better.

<h3>What is a Research Question?</h3>

This refers to "a question that a research project sets out to answer". and seeks to give answers to particular phenomena.

Hence, we can see that the new research question Would be: "Are there any available masks that could prevent fog on glasses that could be improved upon"?

This new research question would help you find out if there is an already existing mask that could be made better.

At an accident scene on a level road, investigators measure a car’s skid mark to be 88 m long. The accident occurred on a rainy
Oduvanchick [21]

Answer:

The the speed of the car is 26.91 m/s.

Explanation:

Given that,

distance d = 88 m

Kinetic friction = 0.42

We need to calculate the the speed of the car

Using  the work-energy principle

work done = change in kinetic energy

W=\Delta K.E

\mu\ mg\times d=\dfrac{1}{2}mv^2

v^2=2\mu g d

Put the value into the formula

v=\sqrt{2\times0.42\times9.8\times88}

v=26.91\ m/s

Hence, The the speed of the car is 26.91 m/s.

A marble, a bowling ball, a basketball, and a baseball are all sitting on the top shelf of a display case. Which one has the gre
Katena32 [7]

Answer:

Bowling Ball

Explanation:

The potential energy depends on the factors: mass of the object and distance between the two objects. In this case the distance is between the ground and the balls. Here, the bowling ball is heaviest and its center of mass is farthest in comparison to other two balls. Thus, it has the greatest potential energy.

Consider a person sliding down a water slide at constant velocity. what are the forces acting on the person as they slide? are t
Andru [333]

Explanation :

When a person is sliding with constant velocity, the forces that are acting on him are :

(1) Weight, W = mg where g is acceleration due to gravity.

(2) Friction forces acting opposite to the direction of motion.

(3) Normal force.

The forces acting on the person is balanced because the person is sliding with constant velocity.

From figure it is clear that, friction force is balanced by w\ sin\theta and normal is balanced by w\ cos\theta.

The process by which the gene in the nucleotide suddenly changes its position is called.
Ksenya-84 [330]

Mutation is the process by which the gene in the nucleotide suddenly changes its position

Any change in the structure of a gen or in the usual DNA sequence of a cell is called mutation. It can be caused by mistakes during cell division when the DNA is copied or by the exposure to DNA damaging agents in the environment like UV light or cigarette smoke, and may be transmitted to subsequent generations.

A mutation is a permanent alteration of the nucleotide sequence of an organism, virus or other genetic elements.

There are three types of mutations:

  • Base substitutions
  • Deletions
  • Insertions

<h3>What is DNA?</h3>

The Deoxyribonucleic acid, also called DNA, is the hereditary material that carries genetic information for the development and functioning of humans and almost all other organisms. DNA is made of nucleotides.
