Answer:
In the grapher: The stops are marked with a flat line, velocity with a diagonal line, and acceleration with a curve.
Average speed= Total distance/Total time
Explanation:
Answer:
Explanation:
Wavelength is the distance between two successive crests of a wave or the <em>distance</em> it takes before the wave's shape repeats itself.
It's given as the velocity of the wave divided by it's frequency.
-Distance between any two wave crests.
-velocity, speed at it the wave is moving in a given direction.
-frequency, number of waves going through a certain point in a acertain time. Measured in cycles/sec or Hz
f=750Hz

Answer:
The tension in string will be "3.62 N".
Explanation:
The given values are:
Length of string:
l = 3 ft
or,
= 0.9144 m
frequency,
f = 60 Hz
Weight,
= 0.096 lb
or,
= 0.0435 kgm/s²
Now,
The mass will be:
