The relationship between the voltage and the current in the circuit is:

where

is the voltage difference, R the resistance of the circuit (and therefore, the resistance of the battery) and I the current flowing in the circuit. By using I=19 A and

, we can find the internal resistance of the battery:
Gravitational energy is the potential energy associated with gravitational force. If an object falls from one point to another inside a gravitational field, the force of gravity will do positive work on the object and the gravitational potential.

<span>when two hydrogen atoms approach each other the potential energy of the combination becomes lower and lower until it reaches a minimum value of -436 kl/mol at a distance of 75 pm</span>
In the opposite figure, the work done by the force F to push the box upwards from the ground to the top of the inclined plane is 600 J.Option c is correct.
<h3>What is work done?</h3>
Work done is defined as the product of applied force and the distance through which the body is displaced on which the force is applied.
The displacement value from the triangle is;

The work done is found as ;

The force F in the opposing figure does 600 J of effort to lift the box from the ground to the top of the inclined plane.
Hence option c is correct.

Umm, I guess it really depends on what these numbers are for but what I can say is if you put this under physics then decimals are used very often and help express parts of numbers for this particular problem.And if it's directly between the two then it's 0.50 added to that smaller number,I hope that helps
