A tall tree has more chance to break during storm why
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.

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.
Between which types of elements do ionic bonds occur, and how do electrons act within the bond?(1 point)
nonmetals and nonmetals, electrons shared
metals and nonmetals, electrons transferred
metals and metals, electrons freely moving
nonmetals and metals, electrons shared
Answer:
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.
What is an ionic bond?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

A mother finds her daughter’s mug of hot cocoa on a table an hour after she had been drinking it. As the mother pours out the cocoa, she sees brown solids in the bottom of the mug. How can this be explained?(1 point)
The cocoa was mixed with hot water, but some cocoa settled as it cooled because the solubility went up.
All dissolved substances will come out of solution over time. If the mother waits long enough, then all of the powder will appear at the bottom of the mug.
The cocoa was mixed with hot water, but some cocoa settled as it cooled because the solubility went down.
This would only happen if too much cocoa powder was added in the first place, because the solubility should not change.

a)What equipment will she need to measure it?
b)Explain how she could use that equipment to measure the density.
Answer:
A) Measuring cup with water and a scale
Explanation:
Fill the measuring cup with water to a certain point, and record the current height of the water. After placing the banana fully into the water, record the new height of the water. Subtract the old height from the new height. Now you have the banana's volume.
Then, place the banana on a scale to get it's mass.

The distance traveled by the car will be equal to 400 m.
The given parameter
distance round the block, d = 400 m
To find:
the distance traveled by a car round the blockTo travel round the block means that the car will complete a distance equal to the distance round the block.
distance round the block = distance traveled by the car = 400 mThus, the distance traveled by the car will be equal to 400 m, since this is equivalent to the distance round the block.

If a body is dropped from the same height once in the equator and then in polar region in which place will it fall faster? why
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.
