Newton's 2nd law of motion says
Net force = (mass) x (acceleration)
Plug in the things you know, and you have
80 N = (20 kg) x (acceleration)
Divide each side by (20 kg) :
80N / 20kg = acceleration
acceleration = 4 m/s²
Answer
given,
Hunk Finn speed,v_y= 0.7 m/s
Speed of river,v_x = 1.50 m/s
Assuming the speed of the river is in x-direction.
Speed of Hunk Finn to be in y-direction.
Hunk velocity relative to river =
Speed of Hunk relative to river = 1.66 m/s
direction of the boat
Hence, angle of the raft is 24.01°
Take the upward and to-the-right directions to be positive (so down and to-the-left are negative).
The vertical forces acting on the object cancel, 6 N - 6 N = 0.
The horizontal forces exert a net force of 20 N - 3 N = 17 N. This net force is positive, so it points to the right. So the answer is A.
Answer:
Spiral Galaxy
Explanation:
Spiral galaxies are named by their spiral structures that extend from the center into the galactic disc. The spiral arms are sites of ongoing star formation and are brighter than the surrounding disc because of the young, hot OB stars that inhabit them.
I think the answer to your question is a galaxy.
