If every 10th student on a non alphabetized list of names was choose from your school to answer a survey, this group would be a
a. independent sample
b. random sample
c. blased sample
d. experimental sample

B. random sample

Explanation:

Every tenth student from a non alphabetized list of names indicates that the surveyor did not intend to have any bias in his survey. Generally, in random sampling a member of the survey is only chosen once i.e., without replacement. Here the surveyor does not have a pattern while choosing the members of the survey.

Hence, this sampling is random sampling.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
