Studying energy involves determining the amount of energy an object has. This energy can be kinetic or potential, or it could be

a combination of both. Consider a 2-kg bowling ball sits on top of a building that is 40 meters tall. It falls toward the ground. Think about the amounts kinetic energy the bowling ball has as it falls, select the when the ball would have the most kinetic energy from the choices given.
Question 1 options:

A. as it is just about to hit the ground from a fall off a building that is 40 meters tall and traveling 28 meters per second.

B. as it is half way through a fall off a building that is 40 meters tall and traveling 19.8 meters per second.

C. as it sits on top of a building that is 40 meters tall.

D after it hits the ground and is no longer moving.

Alona [7]

Answer:

I notice that it's extremely hot after it has been sitting in thr sun for a while. The sun's rays have been directly shining on the car because the car was in the sun's Ray's directly.

List the metals that form only one type of ionn (that is, metals whose charge is invariant from one compound to another).
Serjik [45]

List of the metals that form only one type of ion (that is, metals whose charge is invariant from one compound to another) is below,

Here , we have to list the metals that form only one type of ion (that is, metals whose charge is invariant from one compound to another) and have to identify the group numbers of these metals.

  • Hydrogen        H+
  • Lithium             Li+
  • Sodium            Na+
  • Potassium        K+
  • Rubidium         Rb+
  • Cesium            Cs+
  • Beryllium         Be2+
  • Magnesium  Mg2+
  • Calcium          Ca2+
  • Strontium  Sr2+
  • Barium          Ba2+
  • Aluminum  Al3+
  • Zinc                  Zn2+
  • Scandium  Sc3+
  • Silver          Ag+

Co is stable in both +2 and +3 oxidation state. So it can variable. Li only have +1 charge. So it is invariable from one compound to other.
