Answer:
See the answers below
Explanation:
We can solve both problems using vector sum.
a)
Let's assume the forces that help the diver dive as positive downward, and the forces that oppose upward, as negative
The drag force is horizontal d this way in the horizontal direction we will only have the drag force that produces the water stream.
b)
Let's assume the forces that propel the rocket upwards as positive and forces like the weight of the rocket and other elements as negative forces.
No. That's the description of the wave's 'frequency'.
Refraction of a wave is its behavior when it crosses
the boundary between two different media.
-Geographic north and south poles are determined by the earth's spin.
-Magnetic north and south is determined by the direction a compass points.
