Atomic number. To say "protons" is enough. Definition of proton includes that it is positively charged.
You can't "change" centimeters to meters. But you can describe a length or a distance in terms of either unit. -- If you know the length in centimeters, divide that number by 100 to find the number of meters in the same distance. -- If you know the length in meters, multiply that number by 100 to find the number of centimeters in the same distance.
Either - the R number refers to the ability to block heat transfer, not absorb it.
no electric charge. the nuclear theory at the time explained the atomic masses by assuming the nucleus contained a number of protons equal to the atomic mass number and enough electrons to cancel the charge beyond that of the atomic number of the element.
A cotton is not specific enough to put a number to it. I would measure 10 cotton balls and average the mass. Cotton balls are a fraction of a gram.
The question does not contain enough information. The equation is number of moles = mass (of compound) / molecular mass of compound. You do not know the weight of an apple (cannot get one specific figure for this), nor does an apple have a molecular weight
do different types of apples have the same number of seeds
do different types of apples have the same number of seeds
Not all types of apples have the same number of seeds. I even experimented by cutting ten different types of apples in half and counting the seeds. I found out that McIntosh had the most seeds(9).
Because we need a number to be equal to nothing. (For example: If you had 1 apple & you gave it away, then many apples do you have? You have no apples. No apples = 0 apples.
there's no difference
Not all typs of apples have the same number of seeds even by experimenting you will still fined out some apples have the same number of seeds as other apples do some dont.
Get the total cubes you need and then subtract the given data (Example: Georgia has 30 apples in all. She has 10 red apples. So there is 20 apples left.). Then get the other given data ( Example: the number of green apples is 9 times the number of granny smith apples.). Then times it by a number (Example: 9x2=18 so there are 18 green apples and there are 2 granny smith apples, which equal 20 apples).
3 apples a day
2
If you had 2 apples and I gave you 4 apples what would be the number of apples you then had.
