Answer:

The correct statement is “A solstice because the Earth is very close to the Sun”

Explanation:

The solstice occurs when the sun is closer or further from one of the Earth's hemispheres, increasing the duration of the day in one part of the world, and decreasing its duration in the other. That is, during the solstice, the sun is closer to one of the hemispheres, causing the day to have a longer duration, while the night is longer in the other hemisphere.

In the case of the equinox, the sun is on the equator line, so the day and night in both hemispheres have the same duration. At that time the part of the Earth closest to the Sun is the equator.

The solstice is caused because the axis on which our planet rotates on itself is slightly inclined with respect to the translation plane, this is its trajectory around the Sun.

That implies that different regions of the globe receive more or less light at different times of the year.

The equinox like the solstice is presented twice a year, marking the entrance of the seasons. The sunny days are longer during the summer solstice, while the nights are longer during the winter solstice. The equinox occurs at the beginning of autumn and spring, when the sun is closer to the equator.

So <u><em>the correct statement is “A solstice because the Earth is very close to the Sun” </em></u>

The summer season begins with a solstice and ends with an equinox, in both hemispheres.
Equinoxes and solstices have no connection to the Earth's distance from the sun.
In the northern hemisphere, the Earth is FARTHEST from the sun early in summer, around the first week of July.

How large amount of energy is produced during the fission of uranium

vova2212 [387]

Answer:

answer is a very large amount of energy is produced from a very small mass

Explanation:

nuclear energy is produced either by fusion or fission the former is fusion of lighter atoms into heavier elements while the letter is the splitting of a heavier atom into lighter atoms. both produce tremendous amount of energy fusion causes compassion of mass wild fission reduces it. and produce it. fusion does not produce radioactive particles while fission does (alpha and beta particles and neutrons)

You are asked to calculate an object's velocity.

In order to do so, you must know the object's speed and the direction

in which it's moving, or you must have other information that makes it

possible for you to calculate its speed and direction.

What are the two most common ways to produce hydrogen gas used in fuel cells?

Natali5045456 [20]

Answer:

Steam-methane reforming

Electrolysis of water

Explanation:

Steam methane reforming involves reaction of methane with water in the presence of a catalyst such as nickel to form Carbon oxides and Hydrogen.

CH4 + H2O ⇌ CO + 3 H

Electrolysis of water involves splitting of water through application of electric current to give Hydrogen and Oxygen gas.

2 H2O(l) → 2 H2(g) + O2(g)

Even through there is equal and opposite reaction,usually the two forces are not seen balanced.Why?

Tomtit [17]

Answer:

This may refer to a situation like:

"one person pushes a box, if there is equal and opposite reaction why the box moves and the person does not?"

Remember the second Newton's law:

F = m*a

suppose that the mass of the person is 3 times the mass of the box.

So, if the box has a mass M, the person will have a mass 3*M

Then the Newton's equation for the box when the person pushes with a force F is:

F = M*a

solving for the acceleration, we get:

F/M = a

While the person is also pushed by the box with a force with the same magnitude, then the equation for the person is:

F = (3*M)*a'

Solving for the acceleration, we get:

F/(3M) = a'

Now we can compare the acceleration of the box (F/M) with the acceleration of the person (F/3M).

Is easy to see that the acceleration of the box is 3 times the acceleration of the person.

So regardless of the fact that both the box and the person experience a force with the same magnitude, the box will move more due to this force.

This is why in situations like this, the forces do not seem balanced.

In the photo, a locomotive has broken through the wall of a train station. During the collision, what can be said about the forc

Pavlova-9 [17]

Answer:

Whether the force exerted by the locomotive on the wall was larger

Than the force the locomotive could exert on the wall.

Explanation:

The Newton's third law of motion States that every force have it's equal and opposite reaction force, whose magnitude is the same as the applied force. Therefore the magnitude of these opposite forces will be equal.

So we have;

F12=-F21

F12 is the force in a direction

-F21 is the force in the opposite direction.

Therefore we see that the magnitude of the force the locomotive exerts on the wall is equal to the one the wall exerts on the locomotive. Both magnitudes are equal but in opposite directions.
