What does the formation of magma depend on? The composition of magma depends on the rock it was formed from (by melting), and the conditions of that melting. Magmas derived from the mantle have higher levels of iron, magnesium, and calcium, but they are still likely to be dominated by oxygen and silicon. What are […]

What is the basic principle of operation of DC generators?
What is the basic principle of operation of DC generators? DC generator operates on the principle of the dynamically induced electromagnetic force. When a conductor is placed in a varying magnetic field, an electromotive force gets induced within the conductor. This induced e.m.f magnitude is measured using the equation of the electromotive force of a […]
What is the evidence for time dilation?
What is the evidence for time dilation? Physicists have verified a key prediction of Albert Einstein’s special theory of relativity with unprecedented accuracy. Experiments at a particle accelerator in Germany confirm that time moves slower for a moving clock than for a stationary one. How did Einstein prove time dilation? Einstein’s ‘Time Dilation’ Gets Pinpoint […]
How many drops did Millikan use?
How many drops did Millikan use? Millikan’s paper of 1913 reported on 58 drops. He stated “that this is not a selected group of drops, but represents all the drops experimented upon during 60 consecutive days.” Who did the oil drop experiment? Robert Millikan’s What is the negative effect of space charge? The electrons emitted […]

How much lower was sea-level 10000 years ago?
How much lower was sea-level 10000 years ago? The last Ice Age As a consequence of global warming, albeit naturally, the rate of sea-level rise averaged ~1.2 cm per year for 10,000 years until it levelled off at roughly today’s position ~10,000 years ago. What was the world like 20000 years ago? 20,000 YEARS AGO. […]
What do dogs hear when you talk to them?
What do dogs hear when you talk to them? Dogs hear nearly twice as many frequencies as humans. Your dog might not understand everything you say, but he listens and pays attention similar to the way humans do. The researchers discovered that dogs — like humans — respond not only to the words we say […]
What is fastest thing on earth?
What is fastest thing on earth? Laser beams travel at the speed of light, more than 670 million miles per hour, making them the fastest thing in the universe. What is the fastest a human can travel in space? Surprisingly, the fastest manned mission record still belongs to Apollo 10, which took place back in […]
