What are some positive aspects of GMO's?
They can be produced in mass quantitiesThey can be modified to have better tasteThey can have extra nutrients addedThey don't need pesticidesThere are many other reasons but these are the main few
Is a concrete barrier in a parking lot a mass frame or shell structure?
mass
How do you define structural efficiency score?
If you want to find the structural efficiency the equation for structural efficiency is: maxmum mass the structure can withstand divided by the structure mass.
Why steel not attract steel?
Stainless steels are not magnetic in nature primarily due to its nickel content which alters the structure. Incase of Iron, the nature of iron is magnetic because the iron atoms within the mass that are free to rotate and attract.
Do holes in semiconductor have mass?
no!!!!! holes in semiconductor have no mass! the conventional way to represent holes as positively charged so there should be a question in our mind that they should have some mass,as proton, the only positively charged particle have mass,but it hasn't.actually the electrons are carrying charge in everywhere,the opposite direction of flow of current considered as the direction of conventional current, In the semiconductor also only electron carry charges,so the excessiveness of electron defined a semiconductor as n-type,or donor type(due to doping,i.e.,mixing some impurities with the semiconductor and make the semiconductor to make covalent bond with that element).and where the semiconductor is doped with some element of having only three electrons at the valence cell,the covalent bond have a shortage of electrons to complete the total covalent bond,so the semiconductor become available to add another electron to compete the covalent bond.and hence they are called p-type or acceptor type.so hole is nothing but a convention to denote this lack of electron,i.e.,lack of negative charge and it seems like the semiconductor have a positive charge that balance the electron.so the hole must not have any mass. electron have a mass-1.6*10^-19 kg
Is the relationship between mass and inertia positive or negative?
Yes, a positive relationship.
Is the proton positive negative or neutral?
What is the mass of a proton
Is it true holes have a mass?
The electrons that are missing have a negative effective mass. So the holes have a positive effective mass.
Why is gravity only attractive?
Technically, it's not. It's only attractive between two positive masses or two negative masses. One positive mass and one negative mass would repel each other. It's just that we've never encountered a piece of negative mass yet.
What charges do proton an electrons have?
Pprotons have a positive charge neutrons have no charge and electrons have a negative charge. However the one with the smallest mass is electrons.
What is Mass and Charge?
Mass of a body is a positive quantity. The gravitational force between two masses is always attractive. Electric charge can be positive or negative or zero.
What is isaac newton's 2nd law of motion?
Force is equal to mass multiplied by acceleration. Acceleration is change in velocity either positive or negative. Mass is always positive.
Did Saddam Hussein have a negative or positive impact on humanity?
Negative: He consistently engaged in mass-murder and genocide. He was a horrible person.
Is it possible the black holes create negative matter?
No. There is no such thing as "negative matter." There is a such thing as anti matter, but it still has positive mass.
How do you find the x and y intercept of a negative number?
A number, negative or positive, does not have intercepts. It also does not have time, mass, length, width or political affiliation.
When matter created gravity as antimatter why not create anti-gravity?
"Antimatter" is not negative mass. Mass is a positive quantity for both matter and antimatter. So gravity is always attractive, even if one of the masses in the relationship happens to be antimatter. If such a thing as negative mass exists, then the forces between it and a lump of normal mass would be repulsive ones. Antimatter is observed routinely, but no evidence of negative mass has ever been observed. When matter & antimatter annihilate energy is released per E = mc2 where m corresponds to the sum of their masses. If the antimatter had negative mass then instead of a positron/electron annihilation releasing energy corresponding to twice the electron mass (as it does) the mass of the electron and negative mass of the positron would cancel resulting in no energy release (this does not happen). This proves that both matter & antimatter have positive mass, without even referring to gravity. As they both have positive mass their gravity will be attractive not repulsive.
Based on the data gathered in Millikan's oil-drop experiments the concept of atomic structure was modified Which of the following aspects of the structure of atom was validated by these experiment?
The charge and mass of an electron; I just did this question on masteringchem
