Which direction is relative to magnetic field? The direction of the force due to a magnetic field is perpendicular to the direction of motion. distance away from the wire, and is called the permeability of free space. Magnetic fields are measured in Teslas(T). Why are iron atoms affected by magnetic fields? Iron atoms are ferromagnetic […]

How do you explain weather and climate? Weather can change from minute-to-minute, hour-to-hour, day-to-day, and season-to-season. Climate, is the average of weather over time and space. We hear about weather and climate all of the time. Most of us check the local weather forecast to plan our days. Which season is the most windy? Of […]

Does melting point increase across a period? Melting and boiling points increase across the three metals because of the increasing strength of their metallic bonds. The number of electrons which each atom can contribute to the delocalized “sea of electrons” increases. The atoms also get smaller and have more protons as you go from sodium […]

What do u mean by runoff? noun. something that drains or flows off, as rain that flows off from the land in streams. What is difference between runoff and streamflow? Streamflow, or channel runoff, is the flow of water in streams, rivers, and other channels, and is a major element of the water cycle. It […]

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 […]

What force is needed to give a 2000 kg car? The net force needed is 4000 N . How long will it take to walk 10km? 90 minutes to two hours How many minutes is 25 miles? It is possible to go 25 miles on the interstate in 30 minutes. It can take anywhere from […]

Can a meteor hit the sun? No asteroids have ever been observed to hit the Sun, but that doesn’t mean that they don’t! Orbits within in a Kirkwood gap are not stable, and any asteroid whose orbit wanders into such a region will eventually get pulled into a different orbit, which may take it into […]

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 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 […]
