Deltas and rivers. They then get filtered through the ground and soil
She will need to get the proper training from the school in her state, then she needs to complete the hours required in order to get a cosmetology license and certificate, then she will be able to start finding a job.
The wave travels at the speed of sound in water:
.
The frequency of the wave is
so we can find its wavelength
by using the basic relationship between frequency, wavelength and speed of the wave:
Answer:
Option D - 0.2 s
Explanation:
We are given;
Initial velocity; u = 7 m/s
Height of table; h = 1.8m
Now,since we want to find the time the car spent in the air, we will simply use one of Newton's equation of motion.
Thus;
h = ut + ½gt²
Plugging in the relevant values, we have;
1.8 = 7t + ½(9.8)t²
4.9t² + 7t - 1.8 = 0
Using quadratic formula to find the roots of the equation gives us;
t = -1.65 or 0.22
We can't have negative t value, thus we will pick the positive one.
So, t = 0.22 s
This is approximately 0.2 s
Technically, both B and D are correct when transmitted through solids, but your answer (and the answer I got from taking the test) will be
D) Longitudinal
Hope this helps!
