Which of the following terms describes the motion of particles during the transmission of wave energy?non-recurrent
arbitrary
periodic
unpredictable

Answers

The term that describes a wave energy from the choice is periodic. Wave energy occurs at intervals thus periodic. The main properties of a wave energy are the amplitude, wavelength, frequency and speed. Also, period is a property where it is defined as the time it takes for one complete wave to pass a certain point. 

Answer:

periodic

Manuel releases a pendulum bob. The drawing shows its path. At which point does the pendulum bob have the most gravitational potential energy? a. no differences
b. point D
c. point B
d. point C

Answers

The right answer for the question that is being asked and shown above is that: "c. point B." Manuel releases a pendulum bob. The drawing shows its path. At point B that the pendulum bob have the most gravitational potential energy.

A football is kicked with a velocity of 18 m/s at an angle of 20. What is the balls acceleration in the horizontal direction as it flies through the air

Answers

If we perform all of our experiments on Earth and ignore
air resistance, then vertical acceleration is always 9.8 m/s²
downward, and horizontal acceleration is always zero.

My apex test just corrected my original answer of 9.8 m/s^2 to 0 m/s^2.

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.) 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 set of terms best defines what affects kinetic energy to potential energy, respectively?

Answers

Velocity and height are the terms that best describes what affects kinetic energy and potential energy.

By definition, the kinetic energy is given by:

Where,

m: body mass

v: body speed

On the other hand, the potential energy is:

Where,

m: body mass

g: acceleration of gravity

h: height of the object

Therefore, a set of terms that affects kinetic and potential energy are speed and height, respectively.

Answer:

The set of terms is speed and height, respectively.
