B
Explanation:
state a theory then find examples to support it so that it becomes a law
(5 L/m)x(1,440 m/da)x(365 da/yr)x(20yr)
That's 52,560,000 Liters, or 52,560 m^3.

The current entering the junction is split, with some of it leaving in one direction and the rest leaving the other way. Only part of the current flows through each device. On the other hand, each device "feels" the full voltage of the battery. </span>

Answer:
3.04 m/s
Explanation:
As the woman moves north, the raft moves south.
We then make the following assumptions for easier calculations
Let the motion of the woman = x
Let the motion of the raft = 4.2 - x
Using law of momentum, we see that
m*v = m1*v1, where
m = 56 kg
v = x
m1 = 149 kg
v1 = (4.2 -x)
Substituting the values into the equation, we have
56 * x = 149 (4.2 - x), opening the bracket
56x = 623 - 149x collecting like terms
205x = 623 Divide by 205
x = 623/205
x = 3.04 m/s
This then means that our answer is 3.04 m/s
