A proton and a neutron are each close to a positive nucleus.
How does the charge on the nucleus affect the proton and the neutron, if at all?
A The neutron is attracted; the proton is repelled.
B The neutron is not affected; the proton is repelled.
C The proton is attracted; the neutron is repelled.
D The proton is not


Answer : The same charges will repel, since all protons are positively charged they will all repel so protons will repel. Neutrons don’t carry a charge so they can’t be repelled
So the answer is B: the neutron is not affected; the proton is repelled

An independent variable is the cause. Its value is independent of other variables in your study. A dependent variable is the effect. Its value depends on changes in the independent variable

Variables are the factors or the numbers used as a quantity. The dependent variables are conditional, and the independent variable is the cause that affects the result.

The independent variable of an experiment is the data that is the cause of the experimental design. Its value and result do not depend on other factors and conditions. These values are manipulative and are set by the researcher.

The dependent variables, on the other hand, vary based on the other factors and variables and are the effect that is based on the response and the outcome of the other variables. It is the tested or the measured value.

Therefore, the independent and dependent variables differ based on cause and effect.

Explanation:

Answer:

453.592 grams

Explanation:

Given

Mass = 1 lb

Required.

Convert to grams using dimensional analysis

Represent 1 lb with x g

In unit conversion, we have that.

1 lb = 453.592 g

So:

Getting the equivalent of lb in g, we have:

x g = 1 lb * (453.592 g/ 1 lb)

x g = 1 * 453.592 g

x g = 453.592 grams

Hence:

The equivalent of 1 lb in grams is 453.592 grams

Summary: Astronomers have determined that some carbon-rich exoplanets, given the right circumstances, could be made of diamonds and silica.

As missions like NASA's Hubble Space Telescope, TESS and Kepler continue to provide insights into the properties of exoplanets (planets around other stars), scientists are increasingly able to piece together what these planets look like, what they are made of, and if they could be habitable or even inhabited.

In a new study published recently in The Planetary Science Journal, a team of researchers from Arizona State University (ASU) and the University of Chicago have determined that some carbon-rich exoplanets, given the right circumstances, could be made of diamonds and silica.

"These exoplanets are unlike anything in our solar system," says lead author Harrison Allen-Sutter of ASU's School of Earth and Space Exploration.

Diamond exoplanet formation

When stars and planets are formed, they do so from the same cloud of gas, so their bulk compositions are similar. A star with a lower carbon to oxygen ratio will have planets like Earth, comprised of silicates and oxides with a very small diamond content (Earth's diamond content is about 0.001%).

But exoplanets around stars with a higher carbon to oxygen ratio than our sun are more likely to be carbon-rich. Allen-Sutter and co-authors Emily Garhart, Kurt Leinenweber and Dan Shim of ASU, with Vitali Prakapenka and Eran Greenberg of the University of Chicago, hypothesized that these carbon-rich exoplanets could convert to diamond and silicate, if water (which is abundant in the universe) were present, creating a diamond-rich composition.

To test this hypothesis, the research team needed to mimic the interior of carbide exoplanets using high heat and high pressure. To do so, they used high pressure diamond-anvil cells at co-author Shim's Lab for Earth and Planetary Materials.

First, they immersed silicon carbide in water and compressed the sample between diamonds to a very high pressure. Then, to monitor the reaction between silicon carbide and water, they conducted laser heating at the Argonne National Laboratory in Illinois, taking X-ray measurements while the laser heated the sample at high pressures.

As they predicted, with high heat and pressure, the silicon carbide reacted with water and turned into diamonds and silica.

So far, we have not found life on other planets, but the search continues. Planetary scientists and astrobiologists are using sophisticated instruments in space and on Earth to find planets with the right properties and the right location around their stars where life could exist.

For carbon-rich planets that are the focus of this study, however, they likely do not have the properties needed for life.

While Earth is geologically active (an indicator habitability), the results of this study show that carbon-rich planets are too hard to be geologically active and this lack of geologic activity may make atmospheric composition uninhabitable. Atmospheres are critical for life as it provides us with air to breathe, protection from the harsh environment of space, and even pressure to allow for liquid water.

"Regardless of habitability, this is one additional step in helping us understand and characterize our ever- increasing and improving observations of exoplanets," says Allen-Sutter. "The more we learn, the better we'll be able to interpret new data from upcoming future missions like the James Webb Space Telescope and the Nancy Grace Roman Space Telescope to understand the worlds beyond on our own solar system."

Answer:

1) Yes the density does affect it's melting rate.

Explanation:

Simply because the more rock the more time. For instance an ice cube that is empty inside ( has less density ) will take less to melt. Verses an ice cube that is ice to its inner core ( has more density ) will take more time to melt in the same temperature as the first ice cube.

Answer:

False

Explanation:

The mixture is defined as a chemical substance formed by the combination of two or more substance but do not form any bond together.

Water is not a mixture because the water molecule is consists of two hydrogen (H2) atoms and one oxygen (O) atom bonded together with hydrogen bonds.

Hence, the given statement is "false".

Answer:

36 minutes

Explanation:

You take 165/3= 55 pages per hour.

Take 198-165 = 33 pages left of the book

Take 33/55 = .6 hrs to finish the book.

Take 60(minutes in an hour)*.6= 36 minutes

Explanation:

tan(-300) = tan(-300+360) = tan (60)

here we added 360 degree. where by adding 360 +or- (n×360) to the any angle nothing will change as they called equivalent angles

equivalent angles is by adding +or- n×360 to any angle is equivalent to that angle so tan(-300) = tan(60) then we will calculate tan(60) on the calculator

Answer:

They don't move

Explanation:

it may look like they move but you are moving and you are passing the objects so they are not moving other wise things like some trains or animals they move with you. I hope this helps! :D

The motion of objects that are viewed from your reference frame from both inside and while you travel inside a moving vehicle are not moving. It seems that way because the car you are in is moving, but the surrounding things aren't moving unless they are people, animals, or other cars.

An object changing its position with regard to time is referred to as motion. In mathematics, displacement, distance, velocity, acceleration, and speed are used to explain motion.

Motion is the shift in an object's location with regard to time. Motion includes things like a book tumbling off a table, water running from the faucet, rattling windows, etc. Even the air we breathe has motion to it! The entire universe is in motion.

Because the two observers are using distinct frames of reference, the observations differ. Different frames of reference move in relation to one another. A frame of reference is a collection of coordinates that may be used to calculate the locations and velocities of objects within it.

Thus, The motion of objects that are viewed from your reference frame from both inside and while you travel inside a moving vehicle are not moving.
