What is the difference between negative work and zero work and positive work done?
Apsingh89
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.

When swimming work done is positive or negative?
Positive.
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
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.
Is the work done by the system is considered as positive or on the system is considered as positive?
In thermodynamics, work done by the system is considered positive. Work done on the system is considered 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?
A potential difference is created by separating positive and negative charges, typically by a battery or power source. This separation leads to an imbalance of charge, creating a voltage difference between two points, which can then produce an electric current when a conducting path is provided.
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?
Work done is considered positive when the force applied and the displacement of the object are in the same direction, causing movement in that direction. On the other hand, work done is considered negative when the force applied and the displacement are in opposite directions, resulting in work being done against the direction of the force.
On the basis of gram reaction only can you distinguish between staphylococcus and streptococcus?
Staphylococcus is Gram-positive, forming clusters, while Streptococcus is also Gram-positive but forms chains or pairs. This difference in cell arrangement can help distinguish between the two genera based on Gram staining characteristics.
What happends when you divide a negative number?
When you divide a negative number by a positive number or a positive number by a negative number, the division is done the same way as when both numbers are positive, and the quotient is negative. When dividing a negative number by a negative number, divide as usual, and the quotient is positive. + ÷ + = + + ÷ - = - - ÷ + = - - ÷ - = + + x + = + + x - = - - x + = - - x - = +
