Answer:

Please find the answer in the explanation

Explanation:

In Engineering, safety is very essential and very important for all engineers to stick to.

A.) Wearing metal ring or bracelets.

When their is discharg of electrical charges, wearing of metal rings or braceletsb can allow charges to pass through them into the body which can eventually lead to electrical shock.

B.) Being barefoot

Being bare footed is very dangerous because someone can mistakenly step on naked wire which can lead to electrical shock.

C. Working on a damp concrete floor.

It is very hazardous to be working on a damp concrete floor because of the water moisture. It is very unsafe for any electrical job to be done on any wet area because water can conduct electricity which can lead to electrical shock.

d. Touching grounded conductors while working on electrical equipment

Grounded conductor can allow charges to flow through them. So, it is very unsafe to have them have contact with the body because of electrical charges.

e. Working on electrical equipment with sweaty hands

A sweaty hands contain some content of water which can conduct electricity and lead to electrical shock.

1. Looking at the case study provided under the Companion Material section, what is the main problem that is addressed in this c
Fiesta28 [93]

Incomplete question. However, I provided information that could assist you in identifying the main problem or issue addressed in any case study.

Explanation:

First, note that a case study is simply a learning aid that allows one to learn from a real-life scenario.

To determine the main problems of a case study one needs to:

  • Read the case as many times as possible to become familiar with the message been expressed. For example,<em> by highlighting or underlining the most important facts </em>it can help you to discover the main problem or issue.
  • Check for any facts provided in the case study, by so doing you can identify the most important problems.

Thus, by taking these few steps you may be able to determine the main problem in that case study.

Different Gauss quadrature formulae predict different values for the same integral a. True b. False
scoray [572]

Answer: False

Explanation:

The given statement are false as, the gauss quadrature predicted same value only when their is a minute error at one point and two point rule. It basically given the more precise answer and the answer are only changed by the decimal place. The gauss quadrature method are basically used for calculating the certain integral.

How can you evaluate whether the slope of the dependent variable with an independent variable is the same for each level of the
s2008m [1.1K]

Answer:

By running multiple regression with dummy variables

Explanation:

A dummy variable is a variable that takes on the value 1 or 0. Dummy variables are also called binary

variables. Multiple regression expresses a dependent, or response, variable as a linear

function of two or more independent variables. The slope is the change in the response variable. Therefore, we have to run a multiple regression analysis when the variables are measured in the same measurement.The number of dummy variables you will need to capture a categorical variable

will be one less than the number of categories. When there is no obvious order to the categories or when there are three or more categories and differences between them are not all assumed to be equal, such variables need to be coded as dummy variables for inclusion into a regression model.

A completely reversible heat pump produces heat ata rate of 300 kW to warm a house maintained at 24°C. Theexterior air, which is
Triss [41]

Answer:

Change in entropy S = 0.061

Second law of thermodynamics is satisfied since there is an increase in entropy

Explanation:

Heat Q = 300 kW

T2 = 24°C = 297 K

T1 = 7°C = 280 K

Change in entropy =

S = Q(1/T1 - 1/T2)

= 300(1/280 - 1/297) = 0.061

There is a positive increase in entropy so the second law is satisfied.
