Answer:
The <u>Fruit juice </u> should be put in the cooler, because <u>it has the greatest heat capacity</u> and will therefore, <u>absorb the most heat for each degree it increases in temperature.</u>
Explanation:
in order to understand the answer above we need to know what specific heat capacity is
Specific heat capacity can be defined as the amount of heat required to raise the temperature of a unit mass of a substance by one degree
Looking at the specific heat of each substance suggested we see that the fruit juice has a higher specific heat capacity than others this is because it contains a higher amount of water , generally liquid states of substances have a higher specific heat capacity than other states. The specific heat capacity of fruit juice being the highest among the suggested substances means that it can absorb more heat for each degree temperature of refrigerator.
Answer:
I don't know what you're asking, but I will try my best.
If Susan fertilizes her geranium plants, it will help them blossom. If she over-fertilizes them though, they will die. But yes, in general, they will blossom if Susan fertilizes her geranium plants.
I think that the downstairs would be faster because the water wouldn't have to go all the way up which make it slower
This is Coulomb repulsion. Like charges repel ans opposites attract
Answer:
A )
Explanation:
This change in frequency observation occur due to doppler effect
if the wave source moves,In the time between one wave peak being emitted and the next, the source will have moved so that the shells will no longer be concentric. The wavefronts will get closer together in front of the source as it travels and will be further apart behind it. (see the graph)
when the person standing still in front of the ambulance, he will observe a <em>higher frequency </em>than before as the source travels towards them.
The pitch we hear depends on the frequency of the sound wave.
A high frequency corresponds to a high pitch
as we hear a higher frequency , it makes the <em>pitch higher</em> too
