Electric current is the movement of the electrons caused by potential
difference. For example, in a circuit, the electrons in the bulb will not move
without the potential difference or voltage. When there is voltage, electric
current occurs because there is a driving force for the electrons in the wire
to move.
Answer:
242 lts de fuel
Explanation:
We know density of fuel (is variable) but we can say that is close to 1 Kg/lts.
If we have 110 pounds over maximun certificated gross weight, we need to get rid of that 110 pounds or 110 * 2.2 = 242 Kgs
Now by rule of three
If 1 lt weight 1 kg.
x 242 kgs
x = 242 lts de fuel
Kinetic energy
When the rock starts rolling down the hill it has kinetic energy. When the rock gets to the bottom of the hill and stops, it is no longer in motion therefore it no longer has kinetic energy, the energy has been converted back into potential energy.
The resolution of the angles measured (which is to 2d.p) is greater than the resolution that a normal protractor would show (no d.p)
e.g You can't really put a protractor down and say that's exactly 27.94 degrees, so something more accurate must've been used
