Can a negative number be expressed in scientific notation?
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.
Explain what opposite numbers are?
They are the numbers that are placed on a number line that are exact same distance away from 0
How do you find the square roots of fractions?
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.
Round the number 15.39624 to 2decimal placed?
15.4
Given the F equals 8 G equals -3 and H equals 1 over 2 work out 4F - 5G - 2H?
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.
How are positive and negative numbers placed on a number line?
Positive numbers go to the right of zero, negative numbers go to the left of zero.
What is the difference between positive and negative electric fields?
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.
Where are the positive rational number placed on a horizontal number line?
above 0
What is an ambrotype?
An ambrotype is an early type of photograph in which a glass negative appears positive when placed on a black background.
If you place a positive charge next to a negative charge will repel or attract?
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.
A negatively charged object is placed within a positive electric field. what happens to the object?
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)
What is wrong when your car won't start and the battery cables negative and positive are placed on the wrong post?
It means you probably fried the electronics.
Electric field is positive or negative?
The electric field is a vector quantity that can have both positive and negative values. The sign indicates the direction of the force that a positive test charge would experience if placed in the field: positive for a repulsive force and negative for an attractive force.
When a device uses two batteries why do they have to be placed positive to negative?
When two batteries are connected in series in a device, they have to be placed positive to negative to increase the total voltage output. This connection method increases the overall voltage by summing the individual voltages of each battery. Placing them positive to negative ensures that the voltages add up instead of canceling out.
How do polar molecules align themselves in a field?
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.
What does a positive mean for electric field strength?
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.
Is it true that When an ionic compound such as sodium chloride is placed in water water molecules surround and separate the positive and negative ions?
Yes, it is true
