Give two examples of workplace environments where considerations must be made with respect to the possibility of electric discharges. Explain why this is a necessary concern

Answers

Answer 1
Answer:

Answer:

1.) Oil and gas environment

2.) Mechanical engineering and electrical environment.

Explanation:

1.) Oil and gas environment.

Electricity and electric discharge are recognized as serious workplace hazard in oil and gas companies, exposing employees to burns, fires, and explosions.

2.) Mechanical engineering and electrical environment.

Electricity or electric discharge has long been recognized as a serious workplace hazard, exposing employees to electric shock, electrocution, burns, fires, and explosions. Workers could die from electrocutions at work. This is

accounting for on-the-job fatalities and what makes these more tragic is that most of these fatalities could have been easily avoided.

Which terrestrial planet experiences the shortest year?A. Mars
B. Earth
C. Venus
D. Mercury

Answers

D. Mercury
Its year only takes 88 Earth days.

BTW, you could get this exact information if you visit a revolutionary new search engine called Google. Enter in this exact question and Google will return the answer. :)
Also, you probably should know, the closer the planet is to the Sun, the faster it revolves around it, therefore it has a shorter year, and since Mercury is the first planet next to Sun it means that Mercury has the shortest year ☺

What is the smallest value of the force F such that the 8.0 kg block will not slide down the wall? The coefficient of static friction between the block and the wall is 0.4.Select one:

a. 10N

b. 100N

c. 200N

d. 98N

Answers

The smallest value of the force that will make the block not to slide down is 10 N.

We'll begin by calculating the normal reaction. This can be obtained as follow:

  • Mass (m) = 8 Kg
  • Acceleration due to gravity (g) = 10 m/s²
  • Normal reaction (N) =?

N = mg

N = 8 × 10

N = 80 N

Finally, we shall determine the frictional force.

  • Coefficient of friction (μ) = 0.4
  • Normal reaction (N) = 80 N
  • Frictional Force (F) =?

F = μN

F = 0.4 × 80

F = 32 N

Since the frictional force is 32 N, therefore, a force lesser than the frictional force will make the blocknot to slide down.

From the options given above, only option A has a force that is lesserthan the frictional force.

Therefore, the correct answer to the question is Option A. 10 N

Final answer:

The smallest value of the force that will not slide the 8.0 kg block down the wall is 31.36 N.

Explanation:

To determine the smallest value of the force such that the 8.0 kg block will not slide down the wall, we need to consider the static friction between the block and the wall. The formula for static friction is fs = μs * N, where μs is the coefficient of static friction and N is the normal force. In this case, the normal force is equal to the weight of the block, which is mg = 8.0 kg * 9.8 m/s^2 = 78.4 N. Therefore, the smallest value of the force is equal to the maximum static friction force, which can be calculated as fs = 0.4 * 78.4 N = 31.36 N. So the correct answer is 31.36 N.

Your friend is asked to differentiate between evaporation and boiling.what questions could you ask to make him to know the difference between evaporation and boiling?physics question.

Answers

Answer:

Boiling is the "rapid vaporization of liquid" when the liquid is heated at the point where the pressure of the vapor is equal to the pressure exerted by the atmosphere in the liquid.

So during the boiling, the vaporization of the water is also occurring but is a little bit more complex.

Some questions that you may ask your friend to differentiate those two phenomena are:

Which one is used to cook things like pasta? (boiling)

in which process, a liquid is transformed into a gas? (evaporation)

Which one includes the other? (boiling)

Final answer:

Evaporation and boiling are both phases changes, but they differ in the specifics of how and when they happen. These differences involve the temperature and location within the liquid where they occur, as well as the speed of the process.

Explanation:

To differentiate between evaporation and boiling, you could ask your friend these questions:

  1. Does the process occur at any temperature or only at a specific temperature (the boiling point)? (Evaporation can occur at any temperature while boiling only occurs at the boiling point.)
  2. Does the process occur throughout the liquid or only at the surface? (Boiling occurs throughout the liquid while evaporation happens only at the surface.)
  3. Is the process slow or fast? (Evaporation is a slow process while boiling is relatively quick.)

By asking these questions, your friend will be able to identify the key differences that separate evaporation from boiling.
