The magnitude of a component of a vector must be:

a. equal to the magnitude of the vector.
b. greater than or equal to the magnitude of the vector.
c. less than, equal to, or greater than the magnitude of the vector.
d. less than or equal to the magnitude of the vector.

(d) Less than or equal to the magnitude of vector

Explanation:

The magnitude of any vector is vector sum of magnitude of its component

As magnitude of vector is sum of its component so magnitude of its component never be greater than the magnitude of vector

It can be equal to the magnitude of vector in one case when the magnitude of other component of the vector is zero

So it can be less or equal to the magnitude of vector  

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
