Momentum is the quantity that is a vector.
To clarify:
The representation of the momentum vector is an arrow.
In physics, vectors are often represented graphically by arrows, where the length of the arrow indicates the magnitude of the vector and the direction of the arrow indicates the direction of the vector.
The correct response is: The total momentum can either increase or decrease.
When a net external force is exerted on a system of two interacting objects, the total momentum of the system will change as a result of that force. If the net force is in the direction of the motion, the momentum will increase; if it is against the motion, the momentum will decrease. Thus, the total momentum is not conserved when there is a net external force acting on the system.
The magnitude of momentum (\(p\)) can be calculated using the formula:
\[ p = m \times v \]
where:
Substituting the values:
\[ p = 2 , \text{kg} \times 3 , \text{m/s} = 6 , \text{kg m/s} \]
So, the correct response is 6.0.
The correct response is: the choice and use of words.
Diction refers to the specific words and phrases that an author chooses to convey meaning, tone, and style in their writing. It encompasses not just the selection of words, but also their arrangement and the level of formality or informality used.
The correct response is: the thoughts and associations words evoke.
Connotation refers to the emotional or cultural association that a word carries, beyond its literal or dictionary definition (denotation). For example, the word "home" may connote feelings of warmth, safety, and family, in addition to its literal meaning of a place where one lives.
