Do gravitons have mass? Gravitons do indeed have mass, and their motions generate kinetic energy. Other particles have mass, but they are much larger, much less numerous, and cannot substitute for the gravitational effects which generate space curvature. The great mystery of so-called force at a distance is explained by the mass of gravitons. Are […]
What simple machine is dominoes?
What simple machine is dominoes? lever Did Rube Goldberg build his machines? A prolific cartoonist and visionary, Rube Goldberg has become more famous for the inventions bearing his name than for his cartoons and political illustrations. Within his comic strips Goldberg created extremely complex machines that were built to perform a simple task. What is […]
How did the conflict between England and the colonies develop?
How did the conflict between England and the colonies develop? How did the conflict between England and the colonies develop? England raised money by taxing the colonists and the colonists protested because they had not agreed to new taxes. Parliament believed that they had absolute power over the colonists because they were English citizens. Why […]
What is the main advantages of using a fuse?
What is the main advantages of using a fuse? 1) It is the cheapest form of protection. 2) It doesn’t need any maintenance . 3) Its operation is completely automatic and requires less time as compared to circuit breakers. 4) The smaller sizes of fuse element impose a current limiting effect under short-circuit conditions. What […]
What is the resistance across A and B in the Fig 1 point?
What is the resistance across A and B in the Fig 1 point? ⟹ RAB=4+44×4=2Ω What is the total resistance between points A and point B given below circuit? Therefore, the total resistance in the circuit is 4+4+2=10 ohms. What is resistance between A and B? The three resistance of 20 ohm, 10 ohm and […]
How do the kidneys respond to acidosis?
How do the kidneys respond to acidosis? The kidneys respond to acid-base disturbances by modulating both renal acid excretion and renal bicarbonate excretion. These processes are coordinated to return the extracellular fluid pH, and thus blood pH, to normal following a derangement. What can the kidney do to compensate for acidosis? Renal compensation of respiratory […]
What would happen if there was no hydrosphere on earth?
What would happen if there was no hydrosphere on earth? We know weather happens in the atmosphere, but without the hydrosphere, there would be no water to evaporate and so no cloud or rain could form. Without oceans and land (hydrosphere and geosphere), there would be no wind (as winds are produced by differences of […]
What are SI units of mass?
What is induction conduction and friction when charging an object?
What is induction conduction and friction when charging an object? Friction – the transfer of electrons from one object to the other. Conduction – by having two objects TOUCH each other and transfer electrons from one object to the next. Induction – By inducing electrons to move from one object to the other. What is […]
What is difference between FID and tcD detector?
What is difference between FID and tcD detector? the basic principle of FiD is the ionization of organic compound by burning the compounds in the hydrogen air flame. Meanwhile, the detection of compound by tcD is based on the difference of thermal conductivity properties between the carrier gas and the target being detected. What does […]
