As an element is a pure substance which contains only one kind of atoms ,so nitrogen -N2,contains only one kind of atom which is nitrogen of two atoms. And compound is also a pure substance which contains two or more kind of atoms. ... So,nitrogen is an element not an compound.
Answer:
Pressure increases
Explanation:
"Gay Lussac's Law - states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. If you heat a gas you give the molecules more energy so they move faster. This means more impacts on the walls of the container and an increase in the pressure."
If the mass of one of the objects is doubled, then the force of gravity between them is doubled. ... Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.
Yes. Displacement is a vector, as opposed to distance, which is a scalar. Since displacement is a vector quantity, the negative sign represents direction. As with velocity and acceleration, it just comes down to how you define your coordinate system
