If the boat is i travling at 10 m/s and the river is 8.0 m/s the boats speed is 18.0 m/s
Answer:
His average speed was 10.3199 m/s.
Explanation:
The applicable relationship is N1/N2 = V1/V2, meaning the ratio of primary voltage to secondary voltage is equal to the ratio of primary turns to secondary turns.
Here N1 = 1000, V1 = 250, V2 = 400V and N2 = TBD.
Rewriting the above relationship, N2 = N1 V2/V1 = 1000 x 400/250 = 1600 turns.
Well that depends...what is your question?
Answer:
light doesn't need a medium through which to travel because the speed of light is experimentally constant
