Does Mint(Mentha arvensis) come under the category of sucker or runner or stolon or rhizome? In one of my books,it says,"In plants like mint and jasmine a slender lateral branch arises from the base of the main axis and after growing aerially for some time arch downwards to touch the ground."...

Please explain in detail about this.How will gravitational potential become zero and gravitational field is non-zero??

Exactly!Thanks a zillion!:smile:

But,the answer coming this way is different from the answer given! As per the cube root of volume,answer is coming as 3.33*10^-7 cm,but the answer given is 2.07*10^-7 cm.

the length of the cube which can be obtained by calculating the cube root of the volume.right?

the length of the cube.

But,even so,the cubes would all be immediately adjacent to each other.How will we find the distance between them?

Homework Statement What is the average distance between neighboring molecules if N2 molecule is assumed to be spherical?(Average volume available to a molecule of N2 gas at NTP is 3.72*10^-20 cm^3,which has been calculated by dividing 22.4 litres by Avogadro's number) Homework Equations...

Okay!Thank you very much!:smile:

Thank you.:smile:

Homework Statement Please give an example when the following condition is true- Gravitational Potential is zero and gravitational field intensity is non-zero. Homework Equations The Attempt at a Solution

This is another question from the same topic. "In a solid,the kinetic energy of molecules is less than the magnitude of their potential energy." How did we come to this conclusion?I know it is true for an atom,but why do we say this for molecules of a solid too?

Right,but doesn't the word "average" has any significance here?

Homework Statement Intermolecular forces are 1- Attractive only 2-Repulsive only 3-Long-range 4-Short-range Homework Equations The 1st and 2nd options are not valid as the nature depends on the distance between the molecules. The Attempt at a Solution The answer given is...
