In cosmology, a view that the universe is always expanding but maintaining a constant average density, with matter being continuously created to form new stars and galaxies at the same rate that old ones become unobservable as a consequence of their increasing distance and velocity of recession.
Answer:
128 N
Explanation:
Power can be defined as
<em>F</em> is the force and <em>v</em> is the velocity.
According to the question, <em>P</em> = 5.15 hp = 5.15 × 746 W.
<em>v</em> = 30 m/s
Since most of the power is used to compensate for the energy transformations due to friction forces, the total frictional is 128 N
