Speed of a wave = (wavelength) x (frequency)
Speed of this wave = (100 m) x (5 / sec)
<em>Speed = 500 m/s</em> (about 1,118 miles per hour)
Answer:
p_k=\sqrt{p_x^2+p_y^2}}
Explanation:
Apply the momentum in each direction knowing that the impact is at the same time for the pieces so
So the momentum in the other piece can be find knowing that
So:
To find the velocity knowing the mass
One
If you use the right hand rule for these problems, you usually make your fingers and thumb sit at right angles to each other. What each of the two fingers means and that related to the thumb is a different story. All you have to understand at this point is that all three are mutually perpendicular.
That makes C the answer.
All the other choices don't make that clear.
Two
This is a straight definition question. The definition says exactly what D says.
If velocity is constants there is no acceleration therefore acceleration will equal zero.
