Every one has a reason in life. You may not know what it is just yet, but you do.
Answer:
The resultant velocity of the boat = 5 m/s
The time it will take for the man to reach the other shore of the river = 25 s
Explanation:
width of river = 100 m
The velocity of the motorboat = 4 m/s eastward
The velocity of the water current = 3 m/s northward
The resultant velocity of the boat is:
R^2 = 4^2 + 3^2
= √ (4^2) + (3^2)
= √16 + 9
=√25
= 5 m/s
The time it will take for the man to reach the other shore of the river is:
d = 100 m
v = 4 m/s
t = d / v
t = 100 / 4
t = 25 s
The correct answer for the question, "Where should the property "little voltage loss across long distances" be placed in a Venn Diagram?" is : B) alternating current.
A type of current that periodically reverses in direction is called alternating current.
