Science 6th grade
If an object's velocity changes from 2 meters per second to 6 meters per second in five seconds, its acceleration is calculated as follows:- 6-2)/20 = 80m per second per second or or 80m per second squared (m/s2)
Two cones are similar in shape and the ratio of corresponding lengths is 3:5. (a) if the radius of the smaller cone is 12cm, find the radius of the larger cone. (b) if there is sufficient paint to paint 216 large cones, how many smaller cones can be painted with same amount of...
You are in a speedboat on a river moving in the same direction as the current. The speedometer on the boat shows that its speed is 50 km/h. However, a person on the shore meansures the boat's speed as 57 km/h. How is this possible? The answer is somehow related to the ...
start by changing them to improper fractor and then find a common denominator.
it have different distance...your image is twice the distance as the mirror frame
I am writing a found poem and that is the last line of my stanza... It pass our time away, For it was the end of our vacation.
How can you improve this phase... "For it was the end of our vacation"...i think it sound kind of bad or chessy...
the got the answer however what does "to tlk down to" means?
I searched there but some of them are not related to either difinition to me...
what is the definition for alacrity, condescend, and diligent? The choices are: to talk down to, enthusiasm/speed, and thorough/meticulous.
thank...do you have any suggestions on how to improve them?
What is a root? and please another my other question...thank you
i am in eighth grade too...
i am having a A in english and i lived in California
what should you study for a english benchmark?
i think the next number is 731 too. However my way of doing it is by multipling 3 to the number and substract by 4. So 245*3 is 735 and 735-4 is 731.
another way is... you can substitute the x and try to solve for y. what can 5 go to? 5,10,15,20... so if x=2 then the equation will be 6-5y=25 however -5y cant go to 19 so try another number at the end, you will have x=5 there, 15-5y=25 -5y=10 y=-2 i hope you understand the ...
try to use the electron dot diagram to check your answer!
if there is a faction, you first should multiply the denominator to make it easier...
you can use the foil method if you learn it before...
do anyone know any websites to teach me grammars?..like practice questions or vocabulary test???

why does only covalent bond form between two or more nonmetals but not metals?...i am a eighth grader so i am not sure if i need to know them.
so...what you mean is that ionic bonds attract (mostly) opposite properties elements and covalent bonds attract similar elements
can you simplify the meaning for the third part too...thanx...because i think i am confusing myself...so the covalent is usually the left side and the ionic are usually on the right side...right?
for the established part...i don't get what is "6^12C set at exactly 12.00000"
How two neutral objects may become positively and negatively charges? How is atomic mass established? Which atoms will form covalent bonds and which atoms will form ionic bonds?
the first part applies with the polar and nonpolar...so why polar and polar bonds better than polar with nonpolar?
before you substract, you need to find the common denominator...so the common denominator for 9 and 7 is 63. so you change both into the denominator to 63. there you have 8 7/63-1 54/63 which is 394/64 in improper fraction then you simplify it.
In terms of electrons, how is a covalent bond different from an ionic bond? and ... Explain how attractions between molecules could cause water to have a higher boiling point than carbon dioxide? another question is why when scandium reacts with iodine, the formula of the ...
so...the atoms shared electrons at the same time which means it is the definition of covalent bond...right?
whatever you do to one side, you have to do it to the other side
