Gravity is a force that every mass exerts on every other mass. When you jump up in the air, not only does the Earth
exert a gravitational force on you, but you also exert a gravitational force on the Earth. You, of course, fall back down to
the Earth. Which of the following explains why the Earth is not moving toward you when you jump up in the air?
A. Earth exerts a gravitational force on itself.
B. You don't weigh enough to affect Earth's surface.
C. Your mass is very small compared to Earth's mass.
D. Earth's fixed orbit around the Sun keeps it from moving
Answer:
Brainliest A and I want brainliest please
Explanation:
That pull is gravity at work. Every object in the universe that has mass exerts a gravitational pull, or force, on every other mass. The size of the pull depends on the masses of the objects. You exert a gravitational force on the people around you, but the Gravity or gravitational forces are forces of attraction. We're not talking about finding someone really cute and adorable. It's like the Earth pulling on you and keeping you on the ground. That pull is gravity at work.
Every object in the universe that has mass exerts a gravitational pull, or force, on every other mass. The size of the pull depends on the masses of the objects. You exert a gravitational force on the people around you, but that force isn't very strong, since people aren't very massive. When you look at really large masses, like the Earth and Moon, the gravitational pull becomes very impressive. The gravitational force between the Earth and the molecules of gas in the atmosphere is strong enough to hold the atmosphere close to our surface. Smaller planets, that have less mass, may not be able to hold an atmosphere.at force isn't very strong, since people aren't very massive.
Obviously, gravity is very important on Earth. The Sun's gravitational pull keeps our planet orbiting the Sun. The motion of the Moon is affected by the gravity of the Sun AND the Earth. The Moon's gravity pulls on the Earth and makes the tides rise and fall every day. As the Moon passes over the ocean, there is a swell in the sea level. As the Earth rotates, the Moon passes over new parts of the Earth, causing the swell to move also. The tides are independent of the phase of the moon. The moon has the same amount of pull whether there is a full or new moon. It would still be in the same basic place.

Which of the following statements is true about nuclear fusion? (4 points)
It occurs in the sun.
A heavy atom is split.
It can be controlled easily.
An electron is lost by the atom.
Let's understand Nuclear fusion first:
Nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles.In the core of the Sun, hydrogen is being converted into helium. This is called nuclear fusion. It takes four hydrogen atoms to fuse into each helium atom. During the process some of the mass is converted into energy.Nuclear fusion reactions are difficult to control.Fusion does not produce nuclear waste, only the core of the reactor remains radioactive and only for 100 years.Learn more:

Atomic bombs send out a shock wave when they are detonated. This occurs because the bomb's detonation superheats the air particles nearby, which cause them to bump into other air particles that further the wave. Which statement can most likely be made about the shock waves of atomic bombs? They are a mechanical waves. They are an electromagnetic waves. They will act like x-rays. They will act like light rays.
Answer:
The correct answer is - They are mechanical waves.
Explanation:
Atomic bombs after detonated they send a shock wave that makes a movement of particulate matter that leads to transfer of a high amount of energy that superheats the air medium that travels as a mechanical shock wave.
The shock wave that is sent out by a detonated atomic bomb is a longitudinal mechanical wave that transfers the energy to the neighboring particles of the air.

birds are able to ride these air currents to higher
altitudes.
What process enables birds to fly to higher altitudes without flapping their wings,
while riding these air thermals?
A. convection because warm air sinks and cool air rises.
B. convection because warm air rises and cool air sinks.
C. conduction because warm air sinks and cool air rises.
D. conduction because warm air rises and cool air sinks
Answer:
B. convection because warm air rises and cool air sinks.
Explanation:
The processes that enables birds to fly to higher altitudes without flapping their winds while riding air thermals is called convection.
Convection is one of the forms of heat transfer usually found in gases and liquids.
In convection density differences due to temperature changes causes the circulation. Warm air is less dense and it is hotter. It rises up from the surface where it is warmed Cold air sinks to replace the warm air. Cold air form when the air loses its energy to the surrounding. By virtue of this, birds are able to take advantage of it for their flight.the ion SO-² ia given : find the protons electrons and neurons

what should we use in soap making process:-
a) potassium hydroxide
b) sodium hydroxide (lye)
Explain why it should be used
Answer:
Well either of them can be used but I would say B). Sodium hydroxide
Explanation:
Potassium Hydroxide is a type of lye specifically used to make liquid soap. It is also known as potash, lye or even KOH. This is the chemical that induces saponification of the fats and oils to create liquid soap. ... Our lye calculator makes this easy and allows you to select liquid soap as an option.
Sodium hydroxide, with the formula NaOH, is usually used in products as a pH adjuster. It's also used in soap-making to turn fats and oils into soap. You can find sodium hydroxide (also called caustic soda or lye) in its pure form in the cleaning aisle, since it's also really handy for clearing up clogged drains.

Explanation:
why can't 2 cations form a covalent bond?
Answer:
They differ in their structure and properties. Covalent bonds consist of pairs of electrons shared by two atoms, and bind the atoms in a fixed orientation. Relatively high energies are required to break them (50 - 200 kcal/mol). Whether two atoms can form a covalent bond depends upon their electronegativity i.e. the power of an atom in a molecule to attract electrons to itself. If two atoms differ considerably in their electronegativity - as sodium and chloride do - then one of the atoms will lose its electron to the other atom. This results in a positively charged ion (cation) and negatively charged ion (anion). The bond between these two ions is called an ionic bond.

If you have 10.0 g of hydrogen and 5.0 g of oxygen, what mass of the excess reagent remains after the completion of the reaction?
mass Hydrogen=9.376 g
Further explanationReaction
2H₂+O₂⇒2H₂O
mass H₂ = 10 g
mol H₂(MW=2 g/mol) :
10 : 2 = 5
mass O₂=5 g
mol O₂(MW=32 g/mol) :
5 : 32 = 0.156
O₂ limiting reactant
mol H₂: mol O₂ = 2: 1, so mol H₂ :
2 x 0.156 = 0.312
mol H₂ :
5 - 0.132 =4.688
mass of H₂ :
4.688 x 2 =9.376 g
