1. liquid solution to a. oceans
2. gaseous solution to b. clouds
Not sure about 3 and 4.
3 might be oxygen but I think that's 5. element.
Hope this helps, not sure about water and air though.
Work done is given by the change in kinetic energy of an object
- The kinetic energy of the shovel, the shrub, and in Robert's movement were changed, therefore, work is done in the given processes,
Reason:
Work is done when the total energy of object is affected by the application of force on the object over a distance
Therefore;
- In option <em>A</em>, pushing the shovel into ground (to dig out the dirt) the requires the application of a force (push) over a distance, (into and out of the ground) therefore work is done
- In option <em>B</em>, picking the shrub up gives it gravitational potential energy, therefore, work is done
- In option <em>C</em>, carrying the shrub to the hole does visible work
- In option <em>D</em>, holding the shrub while lowering it into the hole does work by preventing the shrub from falling randomly
Therefore, <u>work is done in the given processes</u>

<span>C. They decay at a predictable rate. IE carbon 14 decay to carbon 12 to understand how long ago something was alive.</span>
Answer:
The answer is SYMBOL B.
Explanation:
The correct schematic is the one that shows three groups of long and short lines. A schematic with one long and one short (one group) would be a one cell; a schematic with a long, a short, a long, a short (two group), would be a two cell; and a schematic with a long, a short, a long, a short, a long and a short (three group), would be a three cell- hence why the answer is symbol B.
I'm not 100% sure but I think the answer is D) In general, the stresses and strains of childcare aren't as severe as those of an empty nest
