I know that particles in a solid are not fixed. They are constantly vibrating about their mean position. That is because of their kinetic energy. I was imagining a situation, lets say solid moves towards left of it's mean position. then the inter-molecular forces of attraction on the left...

I just found out another answer. And I think this was what I was looking for. Thank you all. suppose you have a ball moving in a straight line toward a door. The door is hinged on one side, and the ball is moving toward the other end (the door knob end) of the door. If the door is ajar...

Yeah even I thought about that point. I just can't think of any other.

Only rotating bodies have angular momentum? Is this statement false? I had read it somewhere that it is false that only rotating bodies have angular momentum, angular momentum = moment of inertia * angular velocity. Both deal with rotation. so how is the above statement false?

why is it so?

Is there any particular reason other than "law of nature" for us to consume organic compounds which are high energy compounds. Are inorganic compounds not so energy rich like organic compounds? What are the reasons? I couldn't really figure out where to post this question, in bio or chem.

vaccine may contain attenuated microorganisms, killed microorganisms or toxoids. Certain vaccines contain attenuated forms or killed forms or toxoids. For example, in case of cholera, rabies, hepatitis B, Japanese encephalitis, we use killed form. Why can't we form attenuated forms here? Is...

HIV completes the life cycle and finally causes the breaks down the T helper cells. During this process, are the T helper cells capable of producing interferon? Just curious. Tried to do some research, but couldn't understand what I read. So, kindly explain in a simplified language.

"It's found mainly on the plasma membrane of lymphocytes and probably act as antigen receptors." that is what is written in my textbook on IgD antibody. I just read the basic concept of antibody. According to what I've read, the B lymphocytes produce plasma cell which ultimately gives rise...

Thank You. got it.

Confusion with molecular geometry [carbon tetrachloride] I'm trying to understand the molecular geometry of four different compounds: CCl_{4} ,CHCl_{3} ,CH_{2}Cl_{2} ,CH_{3}Cl Please tell me whether my thinking is right or not[conceptually]. If it's wrong kindly correct me. for...

Thank You very much.

I know the fact that, if the total strength of the nerve signal exceeds the threshold at axon hillock, it triggers an action potential. But if someone asks me a question about axon being the nerve impulse generator or the structure responsible for transfer of information, then I would say that...

My textbook says that, the energy level of an electron is decided by the pattern of charges surrounding it. Can anybody explain how. Simple language please, I'm in 12th grade. Kindly provide example, if possible. Thank you.

I was just studyin kinematics and was wondering what its application in modern world would be, what are the recent scientific developments that uses the concepts of 1 dimensional motion. Can anyone make me get really interested into it by telling me about its applications??
