What is the difference between negative work and zero work and positive work done?
If the angle between the displacement and force applied is less than a right angle, then it is Positive Work done. If the angle between the displacement and the force applied is greater than a right angle then it is Negative Work done. If the displacement and force are at right angles, or either is zero, then it is Zero Work done.
What else can I help you with?
When swimming work done is positive or negative?
Positive.
How do you determine a work done is positive sign or negative sign?
If work is done on the system then it has a negative sign. If work is done by the system then it has a positive sign.
What is the difference between positive and negative masks?
Masks are used to clear the material of a semiconductor. It is done by exposing the silicon wafer to UV rays and then washing it in a solvent.A positive photo mask is used to remove the film wherever the mask is clearA negative photo mask is used to remove the opaqueA positive photo mask requires longer exposure than that of the negative
Is the work done on a system positive or negative?
The work done on a system is positive when energy is added to the system, and negative when energy is removed from the system.
Is the work done by the system is considered as positive or on the system is considered as positive?
Work done by the system is considered as PositiveWork done on the system is considered as Negative
What can be done to counter negative forces?
Positive forces can counter negative forces.
Negative integer is subtracted from a negative integer?
Subtracting a negative is like adding a positive.
Is it possible for a solution to test positive in Benedict's test and negative in barfoed's test?
No! Its not possible for a solution to test positive for benedict`s and test negative for barfoed `s test as both detect the presence of reducing sugars and the only difference between the two tests is that further confirmation of a mono or disaccharide is done in barfoed ` s test.
How do you create a potential difference?
Potential difference arises between two conductors when there is a difference in the charge content between them. So, to create it u can take out or pump in charges, which is the job done by a battery.
Is the work done by friction always negative?
No, the work done by friction can be either positive or negative, depending on the direction of the force and the displacement of the object.
What is voltage difference?
Voltage at a point is defined as the work done by a unit positive charge carrying it from infinity to that point. while volage diffrance between two points is the work done bye unit positive charge from one point to the other point.work may be positive or negative depend upon the nature of charge that's why the potential will be negative or positive .CommentBy definition, voltage means potential difference. For this reason, you cannot have 'a voltage at a point' because potential difference, or voltage, exists between two points. You can, however, have a potential at a point.
When do you say that the work done is positive or negative?
There are different conventions as to what work is negative and what work is positive. The convention used by engineers and physicists is that work done BY the system on its surroundings is positive while work done ON the system by its surroundings is negative. Chemists reverse these conventions.
