Want this question answered?
the lines mean that the positive is going on to the negative
Did you mean "The strength of electric field is positive or negative"? Anyway, there is your answer.. The strength of an electric field E at any point is defined as the electric force F exerted per unit positive electric charge q at that point, or E = F/q.You can say that it is positive.
The coefficient for gravity
No, Celsius is a temperature scale which can go down to -273.15. The hottest temperature attained by scientists is approx 4 trillion degrees and the theoretical maximum is 1.4*10^32 [140 nonillion] degrees. On balance, then, the range of negative temperatures on the Celsius scale is somewhat smaller than the positive temperatures.
An object wont have a force, it will have a force acting on it. If a force acting on an object is negative then that simply means that the objects is in the opposite directon than the defined positive. Eg. An object hitting the ground will exert a force on the ground (F=ma) if we say that up is positive then the force is going to be negative (Acceleration due to gravity will be negative). So the force is not "negative" just opposite to the positive direction. Hope that helps.
1) Positive Temperature Coefficient 2) Positive Train Control.
You mean positive temperature coefficient? Yes conductors as they get heated then due to the nucleii vibrating with greater amplitude would have a grip over the moving electrons and so the resistivity increases with the increase in temperature. Hence positive temperature coefficient.
Of course it is! If the mean of a set of data is negative, then the coefficient of variation will be negative.

A measure of skewness is Pearson's Coefficient of Skew. It is defined as: Pearson's Coefficient = 3(mean - median)/ standard deviation The coefficient is positive when the median is less than the mean and in that case the tail of the distribution is skewed to the right (notionally the positive section of a cartesian frame). When the median is more than the mean, the cofficient is negative and the tail of the distribution is skewed in the left direction i.e. it is longer on the left side than on the right.
its negative! negative reply, answer that is not positive
positive
It can have either a negative or positive trend
Yes, you can have a negative coefficient in a direct variation. So if you had y = -7x, that would be a direct variation. If you have y = -x, I do not know, if that is what you mean. Hope it helped.
IN statistics yes there is a negative mean. Mean is the average of multiple numbers. Negative is opposite of positive.
A negative or a positive! It depends on the question.EXAMPLES-7 + 3 = -4 ( a negative answer)-7 + 8 = 1 (a positive answer)IF you mean a negative times a positive, the answer is negative:-3 x 5 = -15
Negative decibels mean damping (loss) and positive decibels mean amplification (gain).
