What is a unit of measuring rate of electron flow in a circuit called?
Electron flow is known as 'current' the unit of current is an amp
What are the components called that are used to control current in the circuits on the board?
This question makes no sense whatsoever without giving details of "the board" being asked about...There is no point in copying and asking this kind of incomplete fragment from such a homework or exam question.
Is the potential difference across an electric circuit with no element drawing current from it the same at every pt?
Yes, in a circuit with no current draw, the potential difference is the same at every point in the circuit. This is due to the conservation of energy principle in electric circuits.
What causes the convection current to flow up at point D?
At point D, the warmer air near the Earth's surface is heated by the ground, making it less dense and causing it to rise. As the warm air rises, it creates a convection current where cooler air moves in to take its place at the surface, perpetuating the cycle.
In Celsius was 0 always the freezing point of water?
The Celsius temperature scale was changed to its current status shortly after the death of Anders Celsius, who devised the system. Until then, 0 degrees was the boiling point of water and 100 degrees was the freezing point. (see: http://www.answers.com/topic/celsius)
What is the subsolar point?
Subsolar PointBy definition, the subsolar point is the point on the Earth's surface at which the Sun is at its highest (or lowest) latitude at local solar noon. The Subsolar point changes continually as the Earth rotates and seasonally moving from 23.5 degrees South to 23.5 degrees North (the solstices) and back throughout the year. To the extent that the subsolar point is directly beneath the sun (i.e., when the sun's rays are exactly perpendicular to the Earth's surface), it would also be true that the closest point on Earth to the sun at that particular point in time would be the subsolar point.
Which is closer to the earth sun point heat point subsolar point solar point?
The Subsolar Point is the shortest distance between the Earth and Sun. The distance constantly changes, because of orbits, drifts, shifts, tilts, etc. However, by definition, the subsolar point is the point on the Earth's surface where the Sun is at its highest (or lowest) latitude at local solar noon. Subsolar points change daily moving from 23.5° South to 23.5° North (the solstices) and back throughout the year. To the extent that the subsolar point is directly beneath the sun (i.e., when the sun's rays are exactly perpendicular to the Earth's surface), it would also be true that the closest point on Earth to the sun at that particular point in time would be the subsolar point. NOTE: The shortest distance between two bodies forms a perpendicular line between the closest parallel planes of both bodies. Subsolar point is the term used to identify the point on a planet which is closest to the sun at any given moment.
Is the subsolar point on a planet the point that is closest to the sun?
No. The "sub-solar" point is that point on the Earth where the Sun is STRAIGHT UP from there.
Is it true that on December 22 the subsolar point is at the tropic of cancer?
Yes, on December 22 the subsolar point is at the Tropic of Capricorn, not the Tropic of Cancer. The subsolar point shifts between the Tropic of Cancer and the Tropic of Capricorn throughout the year as the Earth moves along its orbit around the Sun.
What is the name of the location where the sun's rays are striking at 90 degrees?
The location where the sun's rays are striking at a 90-degree angle is called the subsolar point. This point moves throughout the day due to Earth's rotation and tilt.
The subsolar point on march 20?
On March 20, the subsolar point, where the sun is directly overhead at noon, is located at the equator (0° latitude). This date marks the vernal equinox in the Northern Hemisphere, resulting in nearly equal day and night lengths across the globe. As the sun moves northward after this point, the Northern Hemisphere begins to experience spring while the Southern Hemisphere transitions into autumn.
What is the name of the location on the surface of the earth that receives insolation when the sun is directly overhead?
When the Sun is directly overhead (at zenith) the point below it is called nadir.
Which Africian countries does the tropic of capicorn pass through?
The Tropic of Capricorn or Southern tropic is the circle of latitude containing the subsolar point on the December solstice. It passes through Namibia, Botswana, South Africa, Mozambique, and Madagascar.
In which direction will each compass point when there is a large current in the direction shown?
When there is a large current in the direction shown, each compass point will point in the same direction as the current.
What is your current cumulative grade point average?
My current cumulative grade point average is 3.8.
Is the perihelion a solar or subsolar point?
"Perihelion" is a place in space, not on the earth. It's the point in the orbit of any member of the solar system where the orbiting object is closest to the sun. Earth reaches its perihelion each year during the first few days of January. In 2010, it was in the 7 PM hour EST on January 2.
What is the rate at which charge passes a given point?
current
