Answer:
He could have shut off the power first and de-energize the circuits in order to prevent being electrocuted.
Explanation:
Electrical Safety is very important, <em>especially for those working in such hazardous situations. </em>Almost all our things in the society are electrically-operated, thus it even becomes relevant to have an idea on how we can prevent from obtaining an electrical shock or burns due to faulty electrical tools.
In the worker's scenario above, it is clear that he did not shut off the power at the circuit breaker panel. This is the most important thing that one must include in his plan when attempting to correct an electrical problem. You must find where the electrical switch, fuses and circuit breakers are at first. Once you find their location, you have to turn them off (even if the circuits are of low-voltage).<u> In order to make sure that they are really turned off, test the circuits first. This will help you ensure that they are, indeed, de-energized.</u>
Answer:5/6
Explanation:
Each Coin has two possible outcomes heads or tails
if there are 3 coins and two outcomes for each coin you multiply 3 and 2 and that is a total of 6 possible outcomes
Since the question is saying it can't have more than 2 heads we subtract what we don't want with the total possible outcomes
Out of the 6 outcomes how many are there where all of the coins land on heads? Only 1
6-1=5
Out of 6 outcomes 5 of them the coins landed on 2 heads or less
5/6
The expression (PE products) - (PE reactants) represents the heat of reaction for a chemical change in terms of PE (potential energy).
<h3>What is potential energy?</h3>
Potential energy is any type of energy stored to perform physical work in a given period of time.
Conversely, kinetic energy is motion (movement) energy used when performing physical work.
In conclusion, the expression (PE products) - (PE reactants) represents the heat of reaction for a chemical change in terms of PE (potential energy).
