13. Describe the differences between an impact socket and a conventional socket.
Answer:
The wall of an impact socket is around 50% thicker than that of a regular socket, making it suitable for use with pneumatic impact tools, whereas regular sockets should only be used on hand tools.
Explanation:
This allows the socket to remain securely attached to the impact wrench anvil, even under high stress situations.
why is it important to push a dolly instead of pulling it?
The reason why it is important to push a dolly instead of pulling it is because;
pushing of the dolly means that the force you apply to the heavy object would be acting in an opposite direction to the force of gravity whereas pulling it will mean the heavy object will be acting in the direction of gravity and as such the object can fall on you.
Dollies are equipment's that are used to move heavy objects around.
Now, when making use of a dolly by pushing, you have to make the dolly lean in such a way that the only part that is in contact with the ground is the tires in order for the dolly to move.
However, when you pull a dolly, you are pulling it in the direction that gravity is acting and so balancing a heavy object and then pulling it towards yourself in the direction it wants to fall will just be improper as it will fall on you in no time.
In conclusion, pushing of the dolly means that the force you apply to the heavy object would be acting in an opposite direction to the force of gravity and as such the heavy object can't fall on you like that.

Explanation:
1. Define “continuous probability distribution” and cite at least 5 types.
2. Define expected value and variance of a continuous random variable.
3. Describe normal distribution and the process of solving probability problems involving normal distribution.
4. Explain normal approximation to binomial distribution and how it is used in solving probability problems.
Continuous variables are variables such as time, pressure, height, length, temperature and weight
The responses are;
1. Continuous probability distribution is a distribution in which the values of
the random variable X is not limited to certain values, and therefore the
values are not countable
Five types of continuous random variable are;
Normal distributionStudent t-distributionChi-square distributionF-distributionChi-square distributionOthers include
Gamma distributionBeta distributionCauchy distribution2. The expected value of a continuous random variable, X, is defined as follows;
[tex]\displaystyle The \ expected \ value, \ E[X] = \int\limits^{\infty}_{-\infty} {x \cdot f(x)} \, dx[/tex]
3. The normal distribution the usual distribution used for variables that are
randomly generated and independent. It is a continuous probability
distribution also referred to as Gaussian distribution
The shape of the graph the normal distribution is bell shaped with the
maximum point being the average or mean value, while the standard
deviation gives the dispersion from the mean
The process of solving probability problems involving normal distributions
includes;
Define the value of the probability required in the following form; p(x < a), p(x > b), p(a < x < b)The z-score of a, (and b) is then determined as follows;
[tex]Z=\dfrac{a-\mu }{\sigma }[/tex], and/or [tex]Z=\dfrac{b-\mu }{\sigma }[/tex]From the z-score obtained above, the value of the probability p(x < a), can be obtained from the Z-tableThe value of p(x > a) = 1 - p(x < a)The value of p(a < x < b) is the difference between p(x < a) and p(x > b), the larger first, to get a positive value4. The normal approximation to the binomial distribution is the use of the
normal (continuous) distribution to approximate the binomial (discrete)
distribution
Using the approximation, we have;
The mean = n·p
The standard deviation, [tex]\sigma = \sqrt{(n \cdot p \cdot (1 - p))}[/tex]
Where;
n = The sample size;
p = The probability value given
With the calculated mean and standard deviation, the z-score and
probability p(x < a), can be found for a particular value, a, using the steps

in which year did the industrial revolution begin in england with the invention of the steam engine?
Answer:
1698
Explanation:
The year the industrial revolution begin in England with the invention of the steam engine was 1760.
The Invention of steam engine in England.James Watt, another Scottish engineer, played a crucial role in improving the efficiency of the steam engine. In the late 18th century, Watt made significant modifications to the design, including the addition of a separate condenser and a governor to regulate steam flow. These improvements made the steam engine much more efficient and practical for a wide range of applications beyond mining, such as powering factories and locomotives.
Watt's improvements, combined with subsequent innovations by other engineers, helped usher in the Industrial Revolution, which transformed England and eventually the world. The steam engine became a fundamental technology for powering machinery, revolutionizing transportation, and driving economic growth.

electrical protective devices are designed to automatically
Answer:
Circuit protection devices are designed to automatically limit or shut off the flow of electricity in the event of a ground-fault, overload, or short circuit in the wiring system. Fuses, circuit breakers, and ground-fault circuit interrupters are three well-known examples of such devices.
Explanation:
Electrical protective devices are designed to automatically cut off the flow of electricity.
What are Electrical protective devices?Electric protective devices Electric power system equipment is used to identify abnormal and unacceptable situations and perform necessary countermeasures. Lightning arresters, surge protectors, fuses, and relays with accompanying circuit breakers, reclosers, and so on are examples of these devices.
As it is known that electrical protective devices are those devices which helps to handle unknown electricity surge. It does so by cutting off the connection automatically.
Hence, electrical protective devices are designed to automatically cut off the flow of electricity.
