Answer:
17.46° W of N
Explanation:
His prow must point westward so that the westward component of his total velocity is equal to the eastward river speed.
3 = 10sinθ
sinθ = 3/10
θ = 17.4576... or about 17.46° W of N
it will take him 5 / 10cos17.46 = 0.52414... hrs. or about 31 min 27 s to cross.
Answer: E) Acceleration, net force
Explanation: In order to explain this problem we have to consirer that the uniform circulat motion has constant angular velocity (ω) and the vector velocity is changed its direction for any point that cover the circle but its modulus is contant and its value is v=ω*R. In order to ensure these conditions, the net force also the accelaration called centripetal must point to the center of the circular trajectory.
Answer:
Real images are formed where rays of light actually converge, whereas virtual images occur with they are perceived to converge. Real images can be produced by passing light through converging lenses or with a concave mirror of some sort.
Explanation:
hope that helped a little :)
Because trees get thier nutrients and energy from the sun. They absorb it through the leaves and it makes them grow strong. then someone cuts down the tree and makes the wood for your fire. So, the fire burns the wood that was made from the tree that got nutrients and grew from the sun.
Answer:
4 m/s
Explanation:
to find m/s, divide the meters term by the seconds term. 100m/25s = 4m/s
