The source has chemical and potential energy which when switched on transforms into a chemical reaction. Potential energy is stored energy. A wire which is part of a circuit carries the electrical energy to the bulb which is a form of light energy. This completes the transformation of potential energy - chemical energy - electrical energy - light energy.
Answer:
I think it is either A or D
The distance in miles from P to Q is 12 miles
<h3>Distances and speed</h3>
Let the distance from P to Q be "d"
Since the formula for calculating speed is expressed as:
For the distance of P to Q
40 = d/t
d = 40t
If he drives back at an average speed of 45mph and 2 mintes less, then;
45 = d/t - 0.033
d = 45 (t - 0.033)
Equating both distances
40t = 45(t - 0.033)
40t = 45t - 1.485
-5t = -1.485
t = 0.297
Get the distance from P to Q:
d = 40(0.297)
d = 11.88 miles
Hence the distance in miles from P to Q is 12 miles

The formula for Sums of squares of the residuals (SSR) is attached below.
Therefore, option B is correct:
B. I would calculate the difference between the observed outcome (Y) and the predicted value of Y (Y_hat), square each one of these differences, and add them up.
In a closed system a reversible chemical reaction will reach a state of dynamic chemical equilibrium when the rate of the forward reaction is to be in or equal to the rate of the reverse reaction.
<h3>What occurs if a reaction reaches dynamic equilibrium in a closed system?</h3>
A closed chemical system is said to attain dynamic equilibrium if the rate of the forward reaction is said to have equals the rate of the backward reaction and also the level of concentrations of products and reactants are said to be the same.
Hence, In a closed system a reversible chemical reaction will reach a state of dynamic chemical equilibrium when the rate of the forward reaction is to be in or equal to the rate of the reverse reaction.
