Answer:
Fossils, Glaciers, Coastlines.
Explanation:
Evidence of plate tectonic theory are fossils, fossils of the same species were found oceans apart. also glaciers evidence of glaciers were found in places with warm climates. coastlines coastlines look like they fit in a puzzle.
Answer: The mass of ice you would need to add to bring the equilibrium temperature of the system to 300 K is kg.
Explanation:
We know that relation between heat energy and specific heat is as follows.
q =
As density of water is 1 kg/L and volume is given as 400,000 L. Therefore, mass of water is as follows.
Mass of water = Volume × Density
=
= 400,000 kg
or, = g (as 1 kg = 1000 g)
Specific heat of water is 4.2 J/gm K. Therefore, change in temperature is as follows.
= 305 K - 273 K
= 32 K
Now, putting the given values into the above formula and calculate the heat energy as follows.
q =
=
= J
or, = kJ
According to the enthalpy of melting of ice 333 kJ/Kg of energy absorbed by by 1 kg of ice. Hence, mass required to absorb energy of kJ is calculated as follows.
Mass =
= kg
Thus, we can conclude that the mass of ice you would need to add to bring the equilibrium temperature of the system to 300 K is kg.
Answer:
I got you
Explanation:
The answer is C. "Our Sun is the center of a solar system in the Milky Way galaxy. My explanation to this being my answer is that the Andromeda galaxy is the only other galaxy on this list yet it is 2.5 million light years away from Earth and the Sun and plus, the Milky Way is the galaxy that contains our solar system, hope that's enough proof and good luck on whatever your working on! :D
