Answer:
F=523712 N
Explanation:
density=mass/volume
and shape is cubic so
volume=(4)^3
volume=64 m^3
mass=835*64
mass=53440 Kg
Hydrostatic force=53440*9.8=523712 N
I think it's C, longer wave length.
In a parallel circuit, the total power supply current is the sum of the
currents through all of the individual branches.
The output current (not the voltage) of the power supply is 5 A.
So the individual currents in the circuit branches is 5 A.
The current through the first 2 resistors is (1 + 0.5) = 1.5 A.
So the current through the 3rd resistor is (5 - 1.5) = <u>3.5 A</u>.
<span> In AC (alternating current) flow, like what comes out of your wall, the flow of electrons changes direction 60 times per second (50 times per second in Europe, China, etc). But in DC (direct current) flow, the average flow of electrons is in one direction only.
I hope it helped you</span>
