The pure moon was not of base earth. What did ancients think of the moon? Through persistent observation, Anaxagoras came to […]

Does changing current affect voltage? To answer this question, the relationship between the voltage and current variables given must be specified. and thus that the current will change proportionally with the voltage. and thus the current will change exponentially with the voltage. Does higher voltage draw less current? If the voltage out is twice that […]

What is the egg drop problem? Egg dropping refers to a class of problems in which it is important to find the correct response without exceeding a (low) number of certain failure states. In a toy example, there is a tower of n floors, and an egg dropper with m ideal eggs. What does Ojo […]

White wires can sometimes act as black wires in 240 volt circuits. Which one of the following is a reliable indicator of service amperage? The answer […]

What is the difference between organ and organ system? An organ is a structure made of two or more tissues that work together for a common purpose. The most complex organisms have organ systems. An organ system is a group of organs that act together to carry out complex, interrelated functions, with each organ focusing […]

Where is the most digested food absorbed? small intestine How does absorption work in the small intestine? Villi That Line the Walls of the Small Intestine Absorb Nutrients. Villi that line the walls of the small intestine absorb nutrients into capillaries of the circulatory system and lacteals of the lymphatic system. Villi contain capillary beds, […]

What is the force in Newtons on each load? The unit of force is the Newton (N) – where one newton is one kilogram metre per second squared. The Newton is defined as the force which, when applied to a mass of one kilogram, gives an acceleration of one meter per second squared. F = […]

What is partial density states? The projected/partial density of states (PDOS) is the relative. contribution of a particular atom/orbital to the total DOS. First moment: The first moment is the center of gravity of PDOS. In other words, first moment is exactly the on-site energy. What is optical joint density of states? The optical joint […]

Which one would have more inertia 10 kg mass & 5 kg mass? Answer. Inertia is the measure of mass. More the mass more will be inertia. So the inertia of 10 kg mass is more than 5 kg mass. Which has more inertia a body of mass 1 kg or hundred kg? Answer. A […]

Which router is elected as the DR? Two rules are used to elect a DR and BDR: router with the highest OSPF priority will become a DR. By default, all routers have a priority of 1. if there is a tie, a router with the highest router ID wins the election. What will an OSPF […]
