Normal force=m*g*cos theta
normal force=92kg*9.8m/s^2*cos 42
normal force=670 N
Answer:
A. 5.600 m
B. 5.800 s
C. 0.966 m/s
D. 0.315 m
Explanation:
A. The wavelength is the distance between 2 crests, which is 5.600 m
B. Period of the wave is the time for the wave to complete 1 circle (highest point to next highest point). Since it takes 2.9s to travel from highest point to lowest point, it would take another 2.9 to travel from lowest point to the next highest point. So the total time is 2.9 + 2.9 = 5.8 s,
C. The wavespeed is wavelength over unit of time:
5.6 / 5.8 = 0.966 m/s
D. The amplitude would be half the length of highest point to lowest point, which is 0.63 / 2 = 0.315 m

<h2>Answer: Sedimentary rocks
</h2>
Sedimentary rocks are formed from sediments and deposits of particles of various types, forms and sizes that are transported by air, wind or water, and then subjected to chemical processes to become rocks.
These types of rocks are usually found in the form of layers or strata in places where sediment accumulates due to the erosion of other materials, for example on the banks of rivers, in valleys, lakes (and any other type of body of water).
