Modern agricultural techniques can increase the production rate of crops and this way we can provide food to all people in short time. On the other hand,these crops are not rich in minerals, irons, carbohydrates, etc.
yes of course.. science is needed for the growth of technology
GMO stands for a Genetically Modified Organism.
the word technology comes from GREEK word Techne means "ART" and Logy means "to talk about something". The specific methods, materials and devices used to solve problem is called technology.
The wire will get hot, the temperature it gets up to will depend on the ampere of the battery and size of wire. The wire can get hot enough to causes burns or start a fire if the battery is large enough. Why this happens is because you have shorted the battery out. The power comes out of the positive post and back in the negative post. When you short it out the power can flow from one post to the other very quickly causing the short to get hot, due to the amount of flow.
Science comes first than technology. Technology is defined as the APPLICATION OF SCIENCE. First basic rules and methods are developed using science and then the they are applied to develop a technology. Example: Steam engines are the result of force provided by steam which is discovered by science.
no, negative....if you multiply two negatives it comes out positive
Both. Positive charge comes from the positive sids (+) and negative charge comes from the negative side (-)
Positive
When it comes to numbers (this question was asked in the "Math and Arithmetic" category), adding a negative number to a positive number always equals a negative number.

The two types of electric charge are positive and negative. Positive charges repel each other, as do negative charges, while opposite charges attract each other.
polar opposites attract. that's where the phrase "opposites attract" comes from.AnswerThere are no such things as 'positive' or 'negative' magnets, other than in the minds of magnetic therapists who seem to have very little scientific knowledge of magnetism! Magnetic poles, not magnets, are named after the directions in which the point when freely suspended -i.e. north and south.

Multiplication or division of two numbers of opposite signs: negative*positive, positive*negative, negative/positive, and positive/negative. Addition of two negative numbers: -5 + -2 = -7 Multiplying pure imaginary numbers of the same 'sign' : 5i * 2i = -10. -3i * -4i = -12. Dividing pure imaginary numbers of different signs (this comes from the fact that 1/i = -i, and i/i = +1)
Modified, as in 'the newly modified roof'.
In order to multiply two numbers together when one or more of them is negative, you start by multiplying them normally. In this case 4x7 = 28. The next step is to assess whether or not the answer is a negative or positive. If the two numbers being multiplied were the same (both negative or both positive) then the answer is positive. Otherwise, it is negative. In this case, we had -4 and -7 which are both negative, so the answer is positive 28. Thus the question can be rewritten as 2x28. This comes out as 56. Therefore 2 times negative 4 times negative 7 is 56.
