The answer is kinetic energy. Hope I helped ^-^

Kinetic energy because there is motion (PE converting to KE). Potential energy is the amount of stored energy.

Real world situation to explain the relationship between work and power

In-s [12.5K]

-- You and your partner both get the same job to do:

Each of you gets a pallet of bricks, and you have to
put the bricks up on the bed of a truck, by hand.
Both pallets have the same number of bricks.

The pallet is way too heavy to lift, so you both cut the bands
that hold the bricks, and you lift the bricks from the pallet onto
the truck, by hand, two or three or four bricks at a time.

-- You get your pallet of bricks onto the truck in 45 minutes.

-- Your partner gets his pallet of bricks onto the truck in 3 days.

-- Work = (force) times (distance).

    You and your partner both lifted the same amount of weight
   up to the same height. You both did the same amount of work.

-- Power = (work done) divided by (time it takes to do the work) .

   Your partner took roughly 96 times as long as you took
   to do the same amount of work.
   You did it faster. He did it slower.
   You produced more power. He produced less power.

olya-2409 [2.1K]

Answer:

Option B) reactive to nonreactive

Explanation:

A) Solid to gas

This might apply, because most of the gases are to the right portion of the periodic table

There are just a few elements that are gases at room temperature; a total of 11: six noble gases (group 18), two halogens (group 17), oxygen (group 16), nitrogen (group 15), and hydrogen (group 1).

Hydrogen is an exception to this trend because they are in the left part of the periodic table.

B) Reactive to nonreactive

The most reactive metals are in group 1 (alkali metals) and the most reactive nonmentals are in the group 18 (halogens). Hence, it is false that the from left to right the preperties go from reactive to nonreactive.

Hence, this is the one that cannot apply.

C) Metal to metalloid to nonmetal

It is true that the metallic character of the elements decreases from left to right; the metals are to the left, going to the right you find some metalloids, and further to the right you find the nonmetals.

Hence, this trend is correct.

D) Increasing number of outer-shell electrons

The number of outer-shell electrons definetly increase from left to right.

The number of electrons in neutral atoms equals the number of protons (to balance the positive and negative charges). Since, the atomic number (the number of protons) increase from left to right, the number of electrons also increase.

In a period (a row of the periodic table) the electrons add to the same outer-shell, then you will find that the number of electrons of the outer-shell increase from left to right. Hence, this is also a correct trend.

In conclusion, the only trend that does not apply is the described by the option B).
