1) c. 2 m/s
Explanation:
The relationship between frequency, wavelength and speed of a wave is
where
v is the speed
is the wavelength
f is the frequency
For the wave in this problem,
f = 4 Hz
So, the speed is
2) a. 2.8 m/s
The speed of the wave on a string is given
where
T is the tension in the string
is the linear mass density
In this problem, we have:
(final tension in the rope, which is twice the initial tension)
--> mass density of the rope
Substituting into the formula, we find
Answer:
<h3>The answer is 3.38 m/s²</h3>Explanation:
The acceleration of an object given it's velocity and time taken can be found by using the formula
where
a is the acceleration
v is the velocity
t is the time
From the question
v = 27 m/s
t = 8 s
We have
We have the final answer as
<h3>3.38 m/s²</h3>Hope this helps you
