Are fixed hard disks portable?
No. "Fixed" means that they are permanently installed in the main frame or tower usually fastened by screws, nuts and bolts. The hard disks that are portable are often called "external drives" meaning that they are not mounted inside of a cabinet and can be freely moved from one location to another.
What does the 302 server response code signify?
The page has temporarily moved
Describe how the computer bus affects the speed of a computer?
BUS speed is used to define how fast data can be copied from one area of the computer to another. The BUS speed can relate to data being moved between memory and the processor, for example. A processor can process at it's peak speed, but the BUS defines how fast the computer can FEED the processor. Two identical processors, one with a 533 mhz FSB and one with an 800 mhz FSB, the 800 mhx FSB will pass data to the processor faster.

When a charge is moved from one point to another in an electric field the work done is?
then our work is positive
Why when a charge is moved from one point to another in an electric field the work done is zero along the direction of the field?
When a charge is moved in the direction of an electric field, no work is done because the force acting on the charge and the displacement are in the same direction. This means that the angle between the force and the displacement is zero, and therefore no work is required to move the charge. This is because the electric field itself is responsible for producing the force that moves the charge.
Does the amount of work per unit charge required to transfer electric charge from the one point to another in an electrostatic field depend on the amount of charge transferred?
No, the amount of work per unit charge required to transfer electric charge in an electrostatic field does not depend on the amount of charge transferred. This quantity is known as the electric potential difference and is a characteristic of the electric field itself, regardless of the charge being moved.
What is the relationship between electric potential scalar and the concept of work done in moving a unit positive charge from one point to another in an electric field?
The electric potential scalar is a measure of the electric potential energy per unit charge at a point in an electric field. The concept of work done in moving a unit positive charge from one point to another in an electric field is related to the change in electric potential between the two points. The work done is equal to the change in electric potential multiplied by the charge being moved.
What force is needed to move an electrically charged body from one point to another?
The force needed to move an electrically charged body from one point to another is determined by the electric field present in the region where the body is being moved. The force is calculated by multiplying the charge of the body by the electric field strength at that point.
What happens when a charged particle is moved along an electric field line?
When a charged particle is moved along an electric field line, it experiences a force in the direction of the field line. This force causes the particle to accelerate in the direction of the field line if the particle has the same charge as the field line, or decelerate if the charges are opposite.
When charged is moved from one point to another in an electric field the work done is?
zero along the direction of d field
What does potential diffrence mean?
Potential Difference is the difference in electric potential energy per coulomb of charge at one point of a circuit compared to the charge at another point in a circuit. Potential difference, or voltage, is a way of describing the energy of an electric field without using test charges. In circuits, potential difference is the difference in voltage from one part of a circuit to another. It can also be described by ohms law where the Voltage=Current*Resistance In electrostatics, potential difference is the line integral of the electric field from one point to another with respect to distance.
How do you determine work done by electric field?
The work done by an electric field on a charged particle can be calculated using the formula: Work = charge of the particle x electric field strength x distance moved. The work is positive if the electric field and the displacement are in the same direction, and negative if they are in opposite directions.
What is work done When a charge is moved from one point to another in an electric field?
consider value of charge =e electric field intensity =E(xyz) now acharge inelectric field experience a force of =eE(XYZ) NOW WORK done to move this particle of distance dl (small lenth) is =eE(xyz).dl (you have to take dot product) now to move this charge praticle from point (x1,y1,z1) To (x2,y2,z2)=intregration of [eE(xyz).dl](x1y1z1)to (x2y2z2)
Relation between potential difference work done and charge moved?
potential difference is the amount of work done in moving a unit charge from one point to another point. potential difference be V ,work done be J and charge be C.V=J\C
Can electric field lines do work?
Yes. Work is force times distance, or technically the dot product of vector force times vector distance. Electric fields exert force on charge and the force does work when the charge moves in the direction of the electric force. (In the converse, when the movement of charge is against the direction of force, work is transformed into stored electromagnetic energy.) Technically, it is the electric field that does work and not the field line. Mother nature produces electric fields, but humans can not see electric fields. Humans invented the idea of field lines to create a mental picture of the field. The two most common ways are to draw lines in space or to draw a collection of arrows in space. Note: One should not confuse this answer with the question of whether work can be done by a magnetic field. A magnetic field can not do work because the direction of the magnetic force is always perpendicular to the direction of motion of charge and hence the dot product of force and distance moved is always zero.
