Answer:
72 volts.
Explanation:
To solve this, we have to use the Ohm's law.
The ohm's law tells us that the voltage drop of a resistor is directly proportional to the current applied to the conductor.
in this case the current is 1.8 amps and the resistor is 40 ohm
so
.
I believe the answer is #4. u can always ask google if u believe that's the wrong answer :)
When you ride a bicycle it means you are moving forward and the wheels of the bicycle are rotating anti- clockwise as viewed from the left side of the bike
Density =mass/volume
Mass=density *volume
=7840*0.08
=627.2kg
Force=mass*g
=627.2*9.81
=6152.8N
