1) BC and CD
2) BC and AC
3) AB and CD

(sorry for the awk looking diagram its supposed to be all connected btw)

Answer:

the answer is b: theory

Explanation:

in science theory can be defined as a scientific idea that uses logic based on wisdom, research, observation, and experience

Explanation:

equator.

because the "belly" of the Earth around the equator makes the Earth there thicker than from pole to pole.

the reason is the spinning of our planet. as the spinning speed is the fastest at the thickest part of a ball (at the equator), that ball has the tendency due to the centrifugal force to extend even further there, and the extra material for that is being pulled in from the poles.

therefore, the diameter through the Earth from equator to equator is larger than the diameter from pole to pole.

and that means that there is more mass from equator to equator than from pole to pole.

and that means that gravity is stronger at the equator.

therefore, a body will fall faster at the equator than on a pole.

Answer:

Fluorescent lamp releases more light energy.

Explanation:

This is so because the fluorescent lamp releases more light energy and less heat energy than that of a filament lamp with the same rating.

Fluorescent lamp releases more light energy than that of filament lamp and also less heat energy than that of a filament lamp.

The filament and the fluorescent lamps are two different types of most commonly used light lamps. The filament lamps are the lamps which work on the phenomenon of incandescent whereas a high resistance filament is heated up in the lamp until it radiates visible light energy. Whereas, a fluorescent lamp is the lamp which works by ionizing a gas that emits photons or energy particles.

The fluorescent lamp releases more light energy and less heat energy than that of a typical filament lamp with the less power of 25W than 50W.

Answer:

6N

Explanation:

F = m × g

= 0.6 × 10

= 6N

to find the force you first have to convert the mass to kg by dividing 600 by 1000 giving you 0.6

then you can multiply the mass times the gravity giving you a gravitational force of 6N

Explanation:

Answer:

yes

Explanation:

because the strong winds and the weight and there are more things to break

Explanation:

A tall tree may have more resistance to the wind since it has more mass ( branches, leaves). That means the wind has more mass to push against. Winds may also be stronger at a higher level. Tall trees have been growing longer and have more chances to have been compromised by insects, animals, fungi and so on. They also have less flexibility since they need to be more rigid to hold up the mass of branches they have.

Answer:

The cocoa was mixed with hot water, but some cocoa settled as it cooled because the solubility went down.

Answer:

C

Explanation:

Answer:

1) They have valence electrons in the same energy level.

2) Helium atoms have 2 valence electrons, while atoms of the other elements in the group all have 8 valence electrons.

3) cesium (Cs)

4) There are two electrons in the first energy level and seven electrons in the second energy level.

In the periodic table, elements are arranged in order of increasing atomic number into groups and periods.

In the periodic table, we have an arrangement of atoms based on their respective groups and periods.

If I pick two representative elements in the same period, their number of valence electrons will differ by 1 but they will all be accommodated in the same energy level.

Helium is the first member of group 18. Unlike the other members of the group, its first shell is also its valence shell. It has two and not eight valence electrons like other members of the group.

The electronic configuration of Ca is [Ar] 4s², that of Li is [He] 2s1, that of Cs is [Xe] 6s1, that of Br is [Ar] 4s² 3d¹⁰ 4p⁵ and that of oxygen is [He] 2s² 2p⁴.

We can see that only Cs has  valence electrons in higher energy orbitals than those of Ca.

Lastly, Fluorine is in group 17. There are nine electrons in this atoms. They arranged in such a way that there are two electrons in the first shell and seven electrons in the second shell.

Answer:

In plotting position versus time it can be seen that the green line represents  a fixed position at the various times given - the other lines represent changing position with time

The (horizontal) green line describes an object that's not moving.

Whatever TIME you pick to look at the green line, its POSITION is always the same. This is a pretty good description of "not moving".

The other three lines all have different positions at different times, so they all describe motion.

Answer:

Experiment

Materials needed

Stop watch, a small stone, a big stone, a balance.

Procedure

Measure the mass of the two stones.

Hold the two stones about 5m above the ground level.

Drop the stones simultaneously.

Record the time taken for the stones to strike the ground.

Repeat the procedure with different masses of objects at the same height.

Observation, it will be observed that, all the objects dropped from the same height strike the ground at the same time interval.

Conclusion; a falling object doesn't depend on mass

Explanation:

½mv²=mgh

g=½(V²/h)

When an object is held at a height, it posses gravitational potential energy which is mgh, where m= mass, h=height, g=acceleration due gravity

When the object is dropped, the potential energy will be converted to kinetic energy which is ½mv², where V=velocity at which the object moves.

V=∆h/t, ∆h is change in height with respect to time.

½mv²=mgh

Mass cancel out,

g=v²/2h

This implies that g does not depend or is not affected by mass. Hence heavy object and light object will reach the ground at the same time when dropped from the same height. When air resistance is negligible.

Im pretty sure that its, the metals and nonmetals, electrons transferred.

Between metals and nonmetals, types of elements do ionic bonds occur, and electrons transferred within the bond,therefore the correct answer is option B.

When two similar or dissimilar atoms form bonds with each other by transferring their valence electron the bond is known as the ionic bond.

The ionic bond is the result of the transfer of the electrons

Ionic bonds are formed between the pair of one electronegative atom and an electropositive atom.

Ionic, covalent, and hydrogen bonds are the three basic types of chemical bonds that are used to generate these chemical compounds from their component atoms.

Ionic bonds are created when electrons are transferred between two bond-forming pairs that can be distinguished by their electronegativity.

Thus, Between metals and nonmetals, types of elements do ionic bonds occur, and electrons are transferred within the bond, therefore the correct answer is option B
