The gravitational potential energy of the object is 100 J.
Gravitational potential energy stored in an object is the work done in raising the object to a height <em>h</em> against the gravitational force acting on it.
The gravitational force acting on a body is its weight mg, where m is its mass and g, the acceleration due to gravity.
Work done by a force is equal to the product of the force and the displacement made by the point of application of the force.
The weight of the object is given as 20 J and it is raised to a height of 5 m.
The gravitational potential energy of the object is 100 J.
<h2>Answer: The second Statement
</h2><h2>The algebraic sum of the currents flowing through each of the three resistors is equal to the current through the battery. </h2><h2 />
In a series circuit, the value of the equivalent resistance is equal to the sum of the values of each of them:
Where:
<h2>The equivalent resistance of the combination of resistors is greater than the resistance of any one of three resistors. </h2>
In this case the current flowing through the resistors is the same in each one. This is because the current flowing through the circuit only has one way to go, so the current intensity is the same throughout the circuit.
Therefore:
<h2>The current flowing through each of the resistors is the same and is equal to the current through the battery. </h2><h2>The algebraic sum of the voltages across the three resistors is equal to the voltage across the battery. </h2>The battery provides a voltage that is the sum of the different voltages at the ends of the resistors:
Where the Voltage, according to Ohm's law is:
Hence, the second statement of this question is <u>True </u>
