We know, wavelength = speed / frequency
w = 10 / 0.5
w = 20 m
In short, Your Answer would be Option C) 20 m
Hope this helps!
The following statements are correct for the electrical (Coulomb) and gravitational forces. The electrical force is inversely proportional to the square of the distance. The gravitational force is also inversely proportional to the square of the distance. Gravitational forces will scale with the amount of mass whilst electrical forces scale with the amount of charge.
Answer:
1000 N
Explanation:
An impulse results in a change of momentum
FΔt = mΔv
F = 0.001 kg(1000 - 0) m/s / 0.001 s = 1000 N
Answer:
net force is positive downward..B
