What is vector ?what is dimension?explain?

Answer»

PLEASE MARK ME BRAINLIST




Vectors in three-dimensional space (1978) is a book concerned with physical quantitiesdefined in "ordinary" 3-space. It was written by J.S.R.Chisholm, an English mathematical physicist, and PUBLISHED by CAMBRIDGE University Press. According to the author, such physical quantities are studied in Newtonian mechanics, fluid mechanics, THEORIES of elasticity and PLASTICITY, non-relativistic quantum mechanics, and many parts of solid state physics. The author further states that "the vector concept developed in two different ways: in a WIDE variety of physical applications, vector notation and techniques became, by the middle of this century, almost universal; on the other hand, pure mathematicians reduced vector algebra to an axiomatic system, and introduced wide generalisations of the concept of a three-dimensional 'vector space'." Chisholm explains that since these two developments proceeded largely independently, there is a need to show how one can be applied to the other

The length of rectangular field is increased by 50percent and its breadth decreased by 50percent to form a new rectangular field. find the percentage change in the area of the field

Answer»

Let the LENGTH and width be a and B

Area = ab

New length = a + a/2 = 3a/2

New width = b - b/2 = b/2

New area = 3a/2 × b/ 2

= 3ab/4

INCREASE in area = ab - 3ab/4

= ab / 4

Percentage of increase = (ab / 4) × 100/ ab

= 100 /4

= 25%

What will be the unit digits of the following

Answer» \textbf{Solution :}
__________

ⓐ 71²

Unit digit of 71² = 1

As, 1² = 1

ⓑ 59²

Unit digit of 59² = 1

As, 9² = 81
We will take only 1 because the que. ASKED for unit digit means digit in ONES place

ⓒ 124²

Unit digit of 124² = 6

As, 4² = 16

ⓓ 86²

Unit digit of 86² = 6

As, 6² = 36

\textbf{Note :} Here we are only taking the digit in ones place.

i.e. 86²

We will take only 6²

•°• 6² = 36
means 6

So, unit digit of 86² = 6
