Is h20 polar covalent bond?
Is h20 polar covalent bond? Water (H2O), like hydrogen fluoride (HF), is a polar covalent molecule. The unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles – a positive charge on the hydrogen pole (side) and a negative charge on the oxygen […]

What is relationship between frequency and amplitude? Frequency is inversely proportional to amplitude. Can amplitude of sine be negative? The difference with a negative value of a however, is our sine curve now has a negative amplitude. In other words, our graphs are the same as when a was a positive value, but are now […]
