Which vectors are unit vectors? the information is on the picture.

Step-by-step explanation:

Unit vector is a vector with mangnitue 1 and we can find out the magnitude of the vector with the following formula

So in the given options whichever vector has magnitude 1 it will be a unit vector.

So if we put the values in the above mentioned formula

1.Magnitude of option A is not 1 so it is not a unit vector

2.Magnitude of option B is  1 so it is a unit vector

3.Magnitude of option C is  1 so it is a unit vector

4.Magnitude of option D is not 1 so it is not a unit vector

whats the

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
