Answer:
Magnitude of the hiker's total displacement = 3.5 km
Angle and direction of the hiker's total displacement = 22 degree south of west
Explanation:
The first Displacement in vector form is
= -4.5 cos 45i +4.5 sin 45j
= -3.182i + 3.182j
The second Displacement in vector form is
= -4.5j
The total displacement is ,
= -3.182i + 3.182j - 4.5j
=-3.182i-1.318j
The magnitude of the displacement is,
s= 3.444
The direction is,
The correct answer is:
That the land where it specifically was has been moving and that years ago that place was under water.
Explanation:
Kansas has been the cause of some of the most luxurious fossil findings in US history. The fossil record of Kansas spans from the Cambrian to the Pleistocene. From the Cambrian to the Devonian, Kansas was coated by a shallow sea.

The rank is : .</h2>
We need to rank the objects according to the magnitude of their momentum.
We know momentum ,{ here m is mass and v is velocity }
Momentum of object A ,
Momentum of object B ,
Momentum of object C ,
Now, we can rank them in order of their magnitude of momentum .
.
Hence, this is the required solution.

Most of the information's required are already given in the question. Based on those information's the answer can be easily deduced.
Wavelength of the sound wave = 0.450 meters
Speed of the sound wave = 330 meters per second
We already know
v=f<span>λ
</span>330 = f * 0.450
f = 330/0.450
= 733.33 hertz
So the frequency of the wave is 733.33 hertz
