Explanation:
The equation for the linear impulse is as follows:
where 
is impulse, 
is the force, and 
is the change in time.
The force, according to Newton's second law:
and since 
the force will be:
replacing in the equation for impulse:
we see that is canceled, so
And according to the problem 
, 
and the mass of the passenger is 
. Thus:
the magnitude of the linear impulse experienced the passenger is 
Answer:
The depth of stream to the student is 
Explanation:
From the question we are told that
The actual depth of the stream is 
The refractive index of the water is 
Generally the apparent depth of the stream is mathematically represented as
substituting values
There are eight octants in the three-dimensional coordinate system. From the word octants you can easily say or associate it to the number 8. Hope this answers the question. Have a nice day. Feel free to ask more questions.
