Work is done when a force is applied to an object through a distance. ... The object will either speed up or slow down, resulting in a change in its kinetic energy (seen in Figure 1), or it will have an altered potential energy if, for example, it was lifted a certain height under the force of gravity.Jan 31, 2020

C.)Cool air near the surface forms high-pressure areas; warm air forms low-pressure areas.
Explanation:
The relationship between air temperature and high and low pressure air is such that cool air near the surface forms high-pressure areas and warm air forms low pressure areas.
- Cool air is closer to the surface because it has low kinetic energy to move. It is denser.
- Warm air rises sharply away from the ground surface.
- They form low pressure areas and their molecules are wide apart due to their high kinetic energy. The air is less dense.

Answer:
Marine life is least affected by the temperature fluctuations of the atmosphere.
Explanation:
The high specific heat capacity of water means that it takes much more energy to raise the temperatures of water by one (1) degree than land. This means that on a hot sunny day, land temperatures would increase dramatically while ocean temperatures would only rise slightly. Conversely, at night, the land cools rapidly while oceans cool slowly hence the temperatures drop slightly.
Answer:
ºC
Explanation:
We have to start with the variables of the problem:
Mass of water = 60 g
Mass of gold = 13.5 g
Initial temperature of water= 19 ºC
Final temperature of water= 20 ºC
<u>Initial temperature of gold= Unknow</u>
Final temperature of gold= 20 ºC
Specific heat of gold = 0.13J/gºC
Specific heat of water = 4.186 J/g°C
Now if we remember the <u>heat equation</u>:
We can relate these equations if we take into account that <u>all heat of gold is transfer to the water</u>, so:
Now we can <u>put the values into the equation</u>:
Now we can <u>solve for the initial temperature of gold</u>, so:
ºC
I hope it helps!
