Need some help with some physics work. i dont want overdue homework.
1.which of the following best describes a scalar value?
a. a measurement in more than one dimension that involves a magnitude and direction
b. a measurement in a single dimension that involves more than one number
c. a measurement that easily scales from one dimension to another
d. a measurement in a single dimension that involves only one number.
2.which of the following is an accurate statement about vectors?
a. rotating a vector about an axis passing through the tip of the vector does not change the vector.
b. the magnitude of a vector can be zero even if one of its components is not zero.
c. if two vectors have unequal magnitudes it is possible that their vector sum is zero.
d. it is possible to add a scalar quantity to a vector
e. the magnitude of a vector may be positive even if all of its components are negative.
that all i need. any help is welcome. thanks in advance.
