Yes, a negative number can be expressed in scientific notation. In scientific notation, a negative number is indicated by the negative sign (-) placed before the first significant digit. The number is then written in the form of a decimal number between 1 and 10, multiplied by a power of 10. For example, -3.2 x 10^-5 is a negative number expressed in scientific notation.
They are the numbers that are placed on a number line that are exact same distance away from 0
Square rootsTo find the square root of a number, you want to find some number that when multiplied by itself gives you the original number. In other words, to find the square root of 25, you want to find the number that when multiplied by itself gives you 25. The square root of 25, then, is 5. The symbol for the square root is . Following is a partial list of perfect (whole number) square roots.Note: If no sign (or a positive sign) is placed in front of the square root, the positive answer is required. No sign means that a positive is understood. Only if a negative sign is in front of the square root is the negative answer required.A fraction, or fractional number, is used to represent a part of a whole. Fractions consist of two numbers: a numerator (which is above the line) and a denominator(which is below the line).So to work out the square root of a fraction you find the square root of the numerator and put it above the square root of the denominator.

You need to replace all the variables with the numbers specifed from above. When a letter and a number are placed side-by-side like you have in your equation that means to multiply. So, when you replace all the variabls with the correct numbers you have: =4(8)-5(-3)-2(1) So, when that is multiplied out you get: =32+15-2 You may see the I added a plus sign in front of the fifteen, when two negative numbers are multiplied the negative numbers become a positive number. When added together you get 45.
Positive numbers go to the right of zero, negative numbers go to the left of zero.
Positive electric fields point away from positive charges and towards negative charges, while negative electric fields point towards positive charges and away from negative charges. In both cases, the direction indicates the direction that a positive test charge would move if placed in that field.

An ambrotype is an early type of photograph in which a glass negative appears positive when placed on a black background.
A positive charge placed next to a negative charge will attract each other due to the difference in their charges. Positive and negative charges attract each other according to the basic principle of electricity.
Electric Field between positive and negative charges. If the Electric Field in which both the positive and negative charges are present is stronger than the Electric Field between the two charges we are talking about, the the negative charge will move away from the positive charge in that positive direction of the field. If not, then the negative charge will get attracted to the positive charge and stay at the position of the positive charge. It will be pulled toward the source of the electric field. (Novanet)
It means you probably fried the electronics.
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.
Batteries placed in series (which is what you're describing) add their voltages together. Thus two 1.5 volt batteries give 3 volts in series ... IF they point in the same direction. If they point in opposite directions, you get zero volts.
Polar molecules align themselves in a field because they have a positive and negative end. When placed in an electric field, the positive end of the molecule will align towards the negative side of the field, while the negative end will align towards the positive side. This alignment helps to minimize the energy of the system.
A positive electric field strength indicates that the field is directed away from a positive charge or towards a negative charge. It signifies the direction in which a positive test charge would move if placed in the electric field.
