Answer:
“I had to cut off the third prong on the electrical plug so that it would fit in the extension cord.”
Explanation:
A good method to find the customer at greater risk of receiving an electric shock is to discard the options.
If we analyze the fourth option "I always make sure that I am standing in a dry area before operating electrical equipment.", we will see that the customer minimizes the risk of electric conduction through a fluid. This precaution also minimizes the risk of electric shock.
The third option "I always read the owner’s manual when I purchase a new electrical appliance." It tells us that the customer knows how to properly use the electrical equipment that manipulates and knows the do and do not of such devices, so the risk of electric shock is reduced.
In the second option, "My bread got stuck in my toaster this morning, and I unplugged it before trying to remove it." The customer made sure to interrupt the electric flow to the device before proceeding and try to remove the jammed bread. If there is no electric current, there will be no electric shock to the customer.
The first option "I had to cut off the third prong on the electrical plug so that it would fit in the extension cord." It tells us that the client altered the cord extension in an inappropriate manner, since the equipment is not designed to work with two prongs. Because the design conditions are not being met, it is possible that the equipment malfunctions and this malfunction could result in the customer receiving an electric shock.
I hope the explanation was clear for you. If you have any further question, I'll be happy to assist you. :D
Given that,
Mass, m = 250 g
Volume of the container, V = 50 cm³
To find,
The density of the oil.
Solution,
Density = mass/ volume
The computation for density is as follows :
So, the density of the oil is 
.
Answer:
Explanation:
The sound moves in the form of waves. The amplitude is the distance between the highest and the lowest point of a wave. In this way the amplitude indicates the amount of energy that a sound signal contains.
Intensity is the amount of acoustic energy that a sound contains. Intensity is measured in decibels. Volume is a measure of the energy that a signal carries, being a magnitude of intensity.
In this way it is possible to say that the energy of a signal is closely related to its amplitude, but its development over time is also important.
The tone or height is the quality that distinguishes between a high or low sound and a low or high sound.
Answer: Only 25% of the intensity of a polarized light wave passes through a polarizing filter. Then the angle between the electric field and the axis of the filter will be 60 degrees.
Explanation: To find the answer of the problem given, we have to know about the Malu's law of polarization.
<h3>
What is Malu's law of polarization?</h3>
- This law states that, when a beam of completely polarized light is passed through an analyzer, then then intensity I of the transmitted light varies directly as the square of the angle
between the transmission direction of the polarizer and the analyzer. - The expression for this law will be,
- Where, I₀ is the maximum intensity of the transmitted light through the polarizer.
<h3>How to solve the problem?</h3>
- From the question, it is clear that, the 25% of the intensity of a polarized light wave passes through the filter.
- Thus, the angle between electric field and the axis of the filter is,
Thus, we can conclude that, the angle between the electric field and the axis of the filter will be 60 degrees.
