Is human eye better than camera?
Is human eye better than camera? Most current digital cameras have 5-20 megapixels, which is often cited as falling far short of our own visual system. This is based on the fact that at 20/20 vision, the human eye is able to resolve the equivalent of a 52 megapixel camera (assuming a 60° angle of […]
What is the Continental Divide and what is its purpose?
What is the Continental Divide and what is its purpose? A continental divide is a boundary that separates a continent’s river systems. Each river system feeds into a distinct ocean, bay, or sea. The Loveland Pass, pictured here, is a continental divide in Colorado that separates water flowing into the Atlantic and Pacific ocean basins. […]
What is the difference between structural and ball and stick model?
What is the difference between structural and ball and stick model? A molecular formula uses chemical symbols and subscripts to indicate the exact numbers of different atoms in a molecule or compound. A structural formula indicates the bonding arrangement of the atoms in the molecule. Ball-and-stick and space-filling models show the geometric arrangement of atoms […]
What is the working principle of capacitor?
What is the working principle of capacitor? A capacitor works on the principle that the capacitance of a conductor increases appreciably when an earthed conductor is brought near it. Hence, a capacitor has two plates separated by a distance having equal and opposite charges. What is the main function of capacitor? A capacitor is an […]
Why diffusion is slowest in solid and fastest in gas?
Why diffusion is slowest in solid and fastest in gas? Diffusion takes place with slowest rate in the case of solids. The rate of diffusion is almost negligible in solids. Since the particles of solid have lowest kinetic energy so they do not move. Hence, diffusion takes a long time in the case of solid. […]
What is nerve impulse in simple words?
What is nerve impulse in simple words? A nerve impulse is the way nerve cells (neurons) communicate with one another. Nerve impulses are mostly electrical signals along the dendrites to produce a nerve impulse or action potential. The action potential is the result of ions moving in and out of the cell. What are the […]
