There are two types of charges namely positive and negative.

Which of the following is true of electrical lines? (a)Like charges attract unlike charges repel. (b)Electrical forces are produced by electrical charges. (c)Positive and negative charges can combine to produce a third type. (d)Electrical forces are weaker than gravitational forces.

Many organic substances are negatively charged e.g., acetic acid, while others are positively charged e.g., ammonium ion. An aminoacid under certain conditions would have both positive and negative charges simultaneously in the same molecule. Such a form of aminoacid is called

An action potential in the nerve fibre is produced when positive and negative charges on the outside and the inside of the axon membrane are reversed because

What is meant by-positive and negative deviations from Raoult's law and how is the sign of 'Delta sol H' related to positive, and negative deviations from Raoult's law?

When electric current is passed through a cell having an electrolyte, the positive ions move towards the cathode and the negative ions towards the anode. If the cathode is pulled out of the solution : The positive ions will start moving towards the anode the negtive ions will stop moving, The positive and negative ions will move towards the anode, The positive and negative ions will start moving randomly, The negative ions will continue to move towards the anode and the positive ionns will stop moving
