<span>During the reading of a blueprint, a general tolerance
pertains to all dimensions that are not independently identified. All tolerances
are +\- .030. General tolerances are mostly found in the blueprint’s set of
information. Let’s say for example, a compact tolerance is required, then a
specific tolerance is considered for specific areas of the blueprint. These
kinds of tolerances are commonly found along the affected area.</span>
The average velocity is -4.17 m/s
Explanation:
The average velocity of a body is given by:

where
d is the displacement of the body
t is the time elapsed
For the student in this problem, we have:
Initial position: 
Final position: 
So the displacement is

The time elapsed is
t = 60 s
Therefore, the average velocity is

Where the negative sign means the student is moving towards the origin.

Answer:
<em>A = 0.05 V</em>
Explanation:
<u>Sinusoidal Functions</u>
A sinusoid or sinusoidal function is a sine or cosine which general equation is

Or also

Where A is the amplitude or maximum value, w is the angular frequency, t is the time and
is the phase shift.
Comparing the given expression with the general formula

We can establish that A=50 mV = 0.05 V
