A woman stands on a bathroom scale in an elevator that is not moving. The scale reads 588 N. The elevator then moves down at an acceleration of - 2.8 m/s2. What does the scale read while the elevator moves down

756 N.

Explanation:

So, we are given the following data or parameters or information which is going to assist us in solving this particular Question or problem effectively;

=> The bathroom scale in an elevator is not moving.

=> " The scale reads 588 N. "

=> "The elevator then moves down at an acceleration of - 2.8 m/s2."

For the second point above: 588 N = mass × gravity.

Thus, the scale that will read while the elevator moves down is given below;

(Mass × gravity) - (mass × acceleration).

(The value of scale when it is not moving) × (1 + acceleration/gravity).

=> 588 × { 1 + 2.8/9.8} = 756 N

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.

  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
