Answer:
Explanation:
Since the cardinal and ball have the same kinetic energy, it is possible to determine the ratio between speeds. (c for cardinal, b for baseball)
The ratio is obtained by multiplying each side by 
:
The value of this ratio is:
V = IR
I = V/R
I = 12/6
I = 2 amps
Beta Carotene is the reason why a carrot is orange. Carotene is a color pigment that is found in large quantities in carrots and it has health benefits as well. The main health benefit of carotene is that our body converts it into vitamin A which is essential.
That is because there are other forces like the friction forces that apply differently on both of them. The frictional forces applied to the sled are smaller than they are on the father, for example, so it's possible for him to pull it.
The average kinetic energy of the molecules of the coffee will decrease and the speed of the individual molecules will also reduce.
<h3>
Temperature of resultant mixture</h3>
The temperature of the resultant mixture will be higher than the cold water temperature and lower than the hot coffee temperature.
Based on the decrease of the resulting temperature (equilibrium temperature) of the mixture, the average kinetic energy of the molecules of the coffee will decrease and the speed of the individual molecules of the hot coffee mixture will reduce, leading to a resultant cold mixture of coffee.
