10m/s - 3m/s = 7m/s
The resultant velocity is 7m/s
Equal forces or balances forces cancel each other out. One side would have to have more force to move in the direction of least force.
Answer:
after 2 seconds its velocity is -20 m/s. after 3 seconds its velocity is -30 m/s. after 10 seconds its velocity is -100 m/s.
Explanation:
This is my answer.
Answer:
A light beam incident on a diffraction grating consists of waves with two different wavelengths. The separation of the two first order lines is great if
the dispersion is great
