Hydrogen.
When they run out of hydrogen fuels in its cores, fusion stops. The collapse of the core causes the temperature to increase in it and around it. Eventually the heat of collapse is enough for the shell of hydrogen are the core to fuse and it turns into a red star.
The potential energy (P.E) of the rock relative to the base of the cliff is 31,054.926 Joules..
<u>Given the following data:</u>
- Acceleration due to gravity = 9.8
To calculate the potential energy (P.E) of the rock relative to the base of the cliff:
<h3>What is potential energy?</h3>
Potential energy (P.E) can be defined as the energy that is possessed by an object due to its position (height) above planet Earth.
Mathematically, potential energy (P.E) is given by this formula;
<u>Where:</u>
- P.E is the potential energy.
- m is the mass of an object.
- g is the acceleration due to gravity.
- h is the height of an object.
Substituting the given parameters into the formula, we have;
P.E = 31,054.926 Joules.

Answer:
<em>a. all three resistors in parallel</em>
Explanation:
<u>Combination of Resistors</u>
The power supplied by a power source or V volts is:
where R is the equivalent resistance of the whole circuit connected to the power source.
As shown, the power is inversely proportional to R which means that if R is a minimum, P is a maximum.
The problem reduces now to find the combination of resistors that produces the least value of its equivalent. If three resistors are connected in series, the equivalent is the sum of all them
This equation gives R a value that is greater than the greatest of all three resistances.
If they are connected in parallel, the equivalent is given by
This equation produces for R a value that is smaller than the smallest value from the three resistances.
Any other combination of resistors will produce intermediate values between the maximum (series) and the minimum (parallel), thus:
a. all three resistors in parallel
