7. Which quantity is the transfer of energy?<br> force<br> motion<br> work
Arisa [49]

In this exercise we have to know the definition of energy to understand what is transferred to a body, like this:

Work

<h2>What is energy?</h2>

Despite being used in many different contexts, the scientific use of the word energy has a well-defined and precise meaning: Innate potential to perform work or perform an action. Anything that is working, moving another object, or heating it up, for example, is expending (transferring) energy.

With this definition we can say that the only alternative that responds to this is work.

Determine the diameter of the largest circular hole that can be punched into a sheet of polystyrene 6 mm thick, knowing that the
Yakvenalex [24]

Answer:

43.41 mm

Explanation:

Given:

thickness of sheet, t = 6 mm

Force exerted by punch, F = 45 KN

Average shearing stress, T = 55 MPa

From average shearing stress T = Force F / Area A

Hence area = force/stress =45000/ 55 =818.18 mm^2

From area = pi*diameter*thickness

diameter = area/(pi* thickness)

= 818.18/(3.142*6)

= 43.41 mm

A periodic wave travels from one medium to another. Which pair of variables are likely to change in the process? A. velocity and
dezoksy [38]

Answer:

A. velocity and wavelength

Explanation:

  • When a wave travels from one medium to another it undergoes a change in direction and this is referred to as refraction.
  • Refraction is the bending of a wave or a change in direction of a wave as it travels from one medium to another. Refraction is accompanied by change in velocity and wavelength of a wave.
  • Velocity of a wave is proportional to the wavelength of the wave therefore, if the velocity of a wave changes the the wavelength will also change proportionally to the velocity.

<span>Well iron, nickle, and cobalt can be natural magnets because they have minerals or metals that generate a stable magnetic field without artificial inducement. A piece of wood cannot be a natural magnet because it does not have metals or minerals that allow it to generate a stable magnetic field. Other types of metals that are magnetic are man made.</span>
