What is the effect of pressure in change of state of matter? Changes in presure have very little effect on the volume of a liquid. Liquids are relatively incompressible because any increase in pressure can only slightly reduce the distance between the closely packed molecules. If the pressure above a liquid is increased sufficiently, the […]
What is the function of pupil of eye?
What is the function of pupil of eye? The function of the pupil is clearly that of controlling the amount of light entering the eye, and hence the light reflex. Can an eye repair itself? Minor superficial scratches on the cornea will usually heal by themselves within two to three days. In the meantime, some […]

Which type of collision is most often seen in football?
Which type of collision is most often seen in football? Perfectly inelastic collisions can be analyzed in terms of momentum. When two objects, such as the two football players, collide and move together as one mass, the collision is called a perfectly inelastic collision. What happens when two tennis balls collide? At impact, the cue […]
Can we see wavelengths?
Can we see wavelengths? More simply, this range of wavelengths is called visible light. Typically, the human eye can detect wavelengths from 380 to 700 nanometers. Does white light exist? White light is actually made of all of the colours of the rainbow because it contains all wavelengths, and it is described as polychromatic light. […]
What rocks is coarse grained?
What rocks is coarse grained? Coarse grain varieties (with mineral grains large enough to see without a magnifying glass) are called phaneritic. Granite and gabbro are examples of phaneritic igneous rocks. Fine grained rocks, where the individual grains are too small to see, are called aphanitic. Basalt is an example. What are the most common […]

What makes the ball keeps on rolling?
What makes the ball keeps on rolling? When a rigid ball rolls on a plane with no other forces, it is known that no friction applies and the ball keeps rolling. Static friction applies in the opposite direction of the tangential part of the external force, with equal magnitude. What do you call the force […]
Is time important in birth chart?
Is time important in birth chart? It allows you to make the appropriate use of your qualities to live up to the best of your capacities. The birth time is not only used to find out the positions of the planets but also your Ascendant (Rising Sign). That calculation then determines the midheaven and the […]
How deep is the Mississippi River at its deepest point?
How deep is the Mississippi River at its deepest point? 61 m Can you eat fish out of the Mississippi River? “We don’t have any advisories on the Mississippi. It’s safe to eat the fish there,” says Langley. Langley says the Mississippi River “has such and immense volume” that it “would wash away just about anything.” […]
