Answer:
B: it can be flattened and bent
Explanation:
Metals are malleable and can be flattened. Metals are ductile and can be deformed and bent.
Metals are bonded together by metallic bonds.
Hence a substance that is composed of atoms that are held together by metallic bonds can be flattened and bent.
The property of a substance that is composed of atoms that are held together by metallic bonds is it can be flattened and bent
What is metallic bond ?Metals are malleable, ductile substance can be deformed when it is bent down, theses are bonded by metallic bond and can be flattened.
The metallic bond is a force of attraction which is responsible for holding the atoms together, releases electrons to achieve the configuration of a noble gas.
in this type of bonding all the atoms lose their electrons from their outermost layers that move more or less freely between them, forming an electronic cloud
The metallic bond is the exceptional bond where the electrons are not present exclusively between a pair of atoms, but these are relocated among millions of them called as "sea of electrons" by cohesive bond.

A student is measuring the volumes of nectar produced by a flowering plant for an experiment. He measures nectar from 50 flowers using a graduated cylinder that measures to the nearest millilitre (mL). Which statement describes a change that can help improve the results of his experiment?
A.) His measurements will be more precise if he takes measurements from an additional 100 flowers. B.) His measurements will be more accurate if he uses a graduated cylinder that measures to the nearest tenth of a mL. C.) His measurements will be more precise if he uses a graduated cylinder that measures to the nearest tenth of a mL. D.) His measurements will be more accurate if he takes measurements from an additional 100 flowers.
NEED HELP NOW PLEASE!!!
Answer:
His measurements will be more precise if he uses a graduated cylinder that measures to the nearest tenth of a mL.
Explanation:
His measurements will be more accurate if he uses a graduated cylinder that measures to the nearest tenth of a mL. The correct option is B.
The closeness of a measurement to the real or recognised value is referred to as accuracy.
The learner can achieve more exact measurements and eliminate the possibility of rounding mistakes by using a graduated cylinder that measures to the closest tenth of a millilitre.
This enhanced precision will help to improve measurement accuracy. Taking measurements from more flowers (options A and D) will expand the sample size but will not enhance accuracy unless the measuring device is updated.
Option C recommends improving precision but does not address accuracy.
Thus, the correct option is B.

how many valence electrons are in the element gallium? explain how you determined the number.
Gallium has three valence electrons.
Elements in the periodic table are classified into groups and periods. Elements in a given group have the same number of valence electrons on their outermost shell while the elements in a period have the same number of shells.
All the elements in group 13 have three electrons in their outermost shell. Gallium is an element of group 13. This means that gallium also has three electrons in its outermost shell(valence electrons).
Learn more: https://brainly.com/question/2673886
Gallium has 3 valence electrons (1 electron in the 4p orbital and 2 electrons in the 4s orbital) because the valence electrons are those located in the outermost energy level of an atom.
Gallium has an atomic number of 31, which means it has 31 electrons in total. The electron configuration of gallium can be represented as [Ar] 3d¹⁰ 4s² 4p¹.
Within the n=4 shell, gallium has electrons in the 4s and 4p orbitals. The 4s orbital can hold a maximum of 2 electrons, while the 4p orbital can hold a maximum of 6 electrons. In the case of gallium, there is 1 electron in the 4p orbital.

Two objects are moving in a straight line. One object has a faster speed than the other. They both have constant speeds (speed is not changing). Is either object accelerating?
Answer:
No
Explanation:
Acceleration refers to the increase in speed over time. Since both of the objects are moving at a constant speed (so the speed is not changing) neither are accelerating, because acceleration requires a positive change in speed.
They may be moving at different speeds, one faster than the other, but neither are changing their own speed so neither are accelerating.
