Answer:

D. near an ocean coastline

Explanation:

The magnetic needle of a compass can be deviated by the magnetic field that the ocean has, this is important to remember because eventhough it´s not a big difference but it is significant enough to keep it in mind. Ocean can attract the magnetic needle of the compass and create a deviation on it.

all white dwarfs have masses in a small range—from about 0.5 to almost 1.4 malchemist sun symbol. why? (select all that apply.)
Minchanka [31]

A white dwarf cannot support its own weight by its degenerate pressure if its mass is greater than 1.4 solar masses.

<h3>What are white dwarfs?</h3>

White dwarfs are stellar core remnant composed mostly of electron-degenerate matter.

White dwarf is very dense due to its large mass and smaller volume.

<h3>Reasons for comparable mass of white dwarfs and Sun</h3>
  • Stars with main sequence masses less than about 0.5 solar masses cannot ignite the helium fusion required to become white dwarfs.
  • A white dwarf cannot support its own weight by its degenerate pressure if its mass is greater than 1.4 solar masses.

The graph below represents the relationship between the force exerted on an elevator and the distance the elevator is lifted.
Stella [2.4K]

I have three problems with this question.

#1). If you copied the question exactly the way it's written,
then the question is written very badly.  The wording is
misleading, and the more you try to think about it and
puzzle it out, the more it'll damage your understanding
of Physics.

There is no relationship between the force exerted on an
elevator and the distance the elevator is lifted.

-- If the force is anything more than the weight of the elevator ...
even one ounce more ... then it'll lift the elevator as high as
you want. 

-- If the force is anything less than the weight of the elevator ...
even one ounce less, then that elevator is headed for the bottom.

#2).  You didn't post any graph below, so if we need the graph
to answer the question, then we can't answer the question.

#3).  I guess that's OK, because you didn't ask any question.

13. Convert 30° C to Fahrenheit<br> doo<br> a. 30 F<br> b. 86 F<br> 34 F<br> d. 100 F
GREYUIT [131]

Answer:86F

Explanation:

Using the formula

F=(°Cx9/5)+32

F=(30x9/5)+32

F=(270/5)+32

F=54+32

F=86F

You connect a 9V battery to a capacitor consisting of two circular plates of radius 0.066 m separated by an air gap of 2.0 mm. W
mel-nik [20]

The charge on the positive plate is 1.734*10^{-12} C

Given,

V=9v, R=0.066m Gap(G)=2.0mm=0.0020m ∈=8.85*10^{-12}

We know C=∈ * \frac{A}{G}= 8.85*10^{-12} *\frac{\pi *0.066^{2} }{0.002}=19.275*10^{-12} F

Also, Q = C V = 19.275*10^{-12} * 9 = 1.734*10^{-12} C

<h3>Charge </h3>

When charged matter is exposed to an electromagnetic field, its electric charge—a property of matter—causes it to feel a force. A charge on an electric field might be positive or negative. Like and unlike charges are attracted to one another while being repelled by the other. Neutral describes a thing without any net charge. Electric charge is a conserved property; in an isolated system, the net charge, or the sum of the positive and negative charges, is constant. Subatomic particles transport electrical charge. The protons in atoms' nuclei carry positive charge in normal matter, while the electrons carry negative charge.
