What is the sign for object and image distances that are measured on the front side of a mirror?
Regardless of which side of the mirror you designate as the positive side, one of them is positive and the other one is negative, since the object and image are always on opposite sides of the mirror. BTW ... If the mirror is flat, then their absolute values are equal.
Can the magnitude of a vector have a negative value and why?
Scalars can be negative, and so can a change in a scalar value.Take temperature:You can have a temperature of -10 degrees.If temperature falls from 20 to 5 degress, the change was -15 degree.The negative value of the scalar is a consequence of where you take the "zero" to be.With speed you have to be very careful because speed is the scalar bit of velocity. Velocity with no consideration of direction.
What is it called when two values change in opposite directions?
The values are said to have negative correlation.Values that change regularly at matching rates are said to be inversely proportional.
What is speed in given direction?
The amount of speed in a given direction is the 'component' of speed in that direction. The total amount of speed AND the direction of the total speed is the 'velocity' of the moving object.
How is it possible for an atom to have no charge even though it is made up of protons neutrons and electrons?
This occurs because the absolute value of the positive charge of the protons, which are concentrated in the nucleus of the atom, is offset by the negative charge of the electrons also in the atom but more diffusely located outside the nucleus. The absolute values of the charge on a proton and the charge on an electron are equal, but the charge on protons is positive and that on electrons is negative. If an atomic size entity contains no electrons, it is not an atom but a positive ion.
Can a body have positive distance but negative speed?
First of all you must be familiar with scalar and vector quantities. A scalar quantity is a physical quantity having only magnitude example length. A vector quantity is a physical quantity having both magnitude and directions. Now speed and distance are both scalar quantities which means their values are always positive. But if you considered velocity then there can be a negative value. Velocity is measured w.r.t the direction the object is going. Conventionally the direction is negative if the object is moving to the left of the initial point and positive for the other way.
Why work is negative its is scalar quantity?
A scalar quantity may have positive and negative values - it is simply a real number. But it doesn't have a direction. Think of it as a "vector in one dimension" - whereas the usual vectors have at least 2 dimensions.
What do you do when subtracting a positive and a negative?
If you subtract a negative from a positive, add both of their absolute values. If you subtract a positive from a negative, add both of their absolute values and multiply by negative one.
Examples of positive and negative values?
Positive values : 1, 2, 3, 4, 5 Positive is a plus. Negative values:-1,-2,-3,-4,-5 Negative is minus.
For what values of n is -2n positive?
[ -2n ] is positive for all negative values of 'n' .
Can probability values be negative?
No. Probability values always have to be positive.
When you add a positive number by a negative number will it be negative or positive?
That depends on the values of the given numbers but a positive number multiplied by a negative number will be negative
Are electron affinity values usually positive or negative numbers?
Positive for nonmetals and negative for metals
How can you define zero?
Zero is the figure or symbol 0, which in the Arabic notation for numbers stands for the absence of quantity. It is a mathematical value intermediate between positive and negative values.
How do you find the quadrant number of a point?
If the points have both positive y-values and x-values it is quadrant 1 If the points have a negative x-value and a positive y-value it is quadrant 2 If the points have both negative y-values and x-values it is quadrant 3 If the points have a positive x-values and a negative y-value it is quadrant 4
Which the function's values become very positive or negative numbers?
The positive regions of a function are those intervals where the function is above the x-axis. It is where the y-values are positive (not zero). The negative regions of a function are those intervals where the function is below the x-axis. It is where the y-values are negative (not zero).
Positive and negative what is the final result?
It depends on the operation and values of the positive and negative. For example, in multiplication or division a positive and negative will be a negative. In addition or subtraction, it depends on the absolute value of the original numbers.
