Answer:
90m/h N
Explanation:
we consider janes velocity to the positive X axis so Vj=280km/s
and the final position a dot in on the graph r=294km, we find the x and y components:
294*cos(17.8)=280 X+ confirming our theory
294*sin(17.8)=90 Y+ or N and that's the winds' velocity.
Answer:
Transverse motion does not produced a doppler effect for a star. As, the doppler effect are occurred when the object are emitting light either in the direction towards the observer or moving away. The various astronomical objects are moving and the observer observed the blue wavelength of the light.
Doppler effect in the star is the process when the observer moves towards the star then it seems like the star move towards the observer.
Answer:
1.24 m/s
Explanation:
Metric unit conversion:
9.25 mm = 0.00925 m
5 mm = 0.005 m
The volume rate that flow through the single pipe is

This volume rate should be constant and divided into the 4 narrower pipes, each of them would have a volume rate of

So the flow speed of each of the narrower pipe is:
