Answer:
Explanation:
A general wave function is given by:
A: amplitude of the wave = 0.075m
k: wave number
w: angular frequency
a) You use the following expressions for the calculation of k, w, T and λ:
b) Hence, the wave function is:
c) for x=3m you have:
d) the speed of the medium:
you can see the velocity of the medium for example for x = 0:
Looking at the force-time graph, wouldn't the force be integral fdt between 0 and 10s, a sort of "smoothed out pulse" ? And it looks like a familiar bell shaped curve. doesn't that produce a turning effect/torque and isn't there something about a circular analogue to F=ma in newtonian linear mechs ???
Looks like a difficult question for 5 points
Atmospheric pressure is caused by the weight of the air above you. It seems silly , but you have to rememeber that the air is full of molecules of different elements ( nitrogen , oxygen , CO2 , etc ... ) and the have atomic weight.
Thats why there is less pressure on top of you when you are at greater altitudes , there is less air above you.
Hope it helps !
It would be awesome if you marked this awnser as Branliest! Thx :)
