Answer:
44.7 degree (3 s.f)
Explanation:
mass of water = 4.10Kg
Initial temperature = 37.5C
Final temperature = x
Heat = 125 kJ = 125000 J
Specific heat capacity = 4180 J/kg°C
These parameters are given by:
H = MCΔT
ΔT = H / MC
ΔT = 125000 / (4.10 * 4180)
ΔT = 7.294
ΔT = T2 - T1
T2 = ΔT + T1
T2 = 7.294 + 37.5
T2 = 44.794 = 44.7 degree (3 s.f)
Well thats because things changed in science. Newtons law of gravity (which was all things that come up must come down) evolved once scientist figured out that in space things float around. Science always evolves weather it's in a year or a day, but if your asking about HOW it evolved, thats something different. Hope I'm helping you!
You could compare it to Washington D.C. It runs the cell as our capitol runs our government. It can be the "heart" of the cell. <span />
Light rays from the sun only strikes the surface of the Earth facing it, and since the Earth is not flat, but geoid, or spherical, then there will always be places backing the light rays of the sun. Now, had the Earth not been rotating about its axis, the place facing the sun would forever remain facing the sun, likewise for the other part backing it. So, there would never be night for those living on the side of Earth facing the sun, and there would never be day for those backing it.
However, since the Earth rotates, then the part facing the sun would slowly move away from it, and the part of the sun backing it would slowly move towards it, causing night time for the former, and day time to the latter.
Now, the place once backing the sun, B, is now facing the sun, and the place once facing the sun, A, is now backing it. But since the Earth continuously rotates, then B would now be slowly inching away from the sun, and A would be slowly inching towards it.
Thus, causing night at B, and day at A, and thus the circle continues, until some external force slows the Earth's rotation to a halt.
Aldehydes are usually more reactive<span> toward nucleophilic substitutions </span>than<span> ketones because of both steric and electronic effects. In aldehydes, the relatively small hydrogen atom is attached to one side of the carbonyl group, while a larger R group is affixed to the other side.</span>
