To find the net force acting on the runner, you need to consider the forces acting on them.
The runner exerts a force of 325 N to the right, and the air resistance force is 45 N to the left.
Net force can be calculated as:
\[ \text{Net force} = \text{Force to the right} - \text{Force to the left} \]
Substituting the values:
\[ \text{Net force} = 325 , \text{N} - 45 , \text{N} = 280 , \text{N} \]
Therefore, the net force of the runner is 280 N.
The correct description of velocity from the options provided is:
Velocity is the speed of an object in a particular direction.
Velocity is a vector quantity that specifies both the speed (magnitude) of an object and the direction in which it is moving.
To determine the direction in which the book will move, we need to calculate the net force acting on it.
The applied force (pushing force) is 7 N to the right, and the frictional force is 3 N to the left.
Net force can be calculated as:
\[ \text{Net force} = \text{Applied force} - \text{Frictional force} = 7 , \text{N} - 3 , \text{N} = 4 , \text{N} \text{ (to the right)} \]
Since the net force is positive and directed to the right, the book will move in that direction.
The correct response is:
The book will move to the right.
The correct definition of a word's connotation is:
the feeling the word gives the reader.
Connotation refers to the emotional or cultural association that a word carries, beyond its literal definition (denotation).
The author uses euphemism:
to insult Tom without being too harsh or direct.
In the paragraph, phrases like "a bit style-challenged" and "his humor leaves a lot to be desired" are softened expressions that serve to critique Tom while maintaining a gentler tone, indicating a less direct form of criticism.
An oxymoron uses the method of:
placing two words with opposite meanings together.
This rhetorical device combines contradictory terms to create a unique or thought-provoking effect, highlighting a paradox or irony.
