Answer:
The magnitude = 10.30 m
The direction of the vector proceeds at angle of 119.05°
Explanation:
Given that:
A vector has component
= -5 m and
= 9 m
The magnitude of vector can be represented as:
=
=
=
=
= 10.30 m
If we make an angle
with y- axis:
Then; tan =
tan =
tan = 0.555
= tan⁻¹ (0.555)
= 29.05°
Angle with positive x-axis = 90 +
= 90° + 29.05°
= 119.05°
Yes
Explanation:
From the graph, we can deduce that the wavelength changes with the speed of the wave.
This is a simple linear graph. A linear graph has a steady gradient and it shows two variables that increases proportionately.
Using the graph, we can establish that as the wavelength of the wave increases the time taken for one wave to pass through increases.
The speed of a wave is given as:
V = fλ
f is the frequency of the wave i.e the number of waves that passes through a point per unit of time
λ is the wavelength of the wave
The vertical axis on the graph shows the time for 1 wave trip, this is the wave period, T
f =
Therefore;
speed of the wave =
This can be evaluated by solving slope of the graph and finding the inverse.
We can see that as the speed of the wave changes, the wavelength will change.
