Yes
Explanation:
There would be a difference in temperature between the two places over the time interval.
What is temperature?
Temperature is the degree of hotness or coldness of a body. It is measured using a thermometer as described in the set up.
Temperature changes is a result of heat transfer.
The sun is the ultimate source of energy for the earth.
It transfers heat to the earth by radiation.
Under a shade, the tree leaves or shed will cut off the radiation preventing it from reaching the surface. This place will be cool and at a lower temperature than expected.
The thermometer furnished with direct sunlight will have a higher temperature. As the radiation from sun hits the surface, it causes it to warm up and increase in temperature. This will cause the thermometer's temperature to also rise.

-- The density of the glass alone doesn't change.
-- The density of the water alone doesn't change.
-- The density of (the entire glass + everything IN IT) increases,
because the part that used to be air (with very low density) is
changed to water (with much higher density than the air had).
Answer:
D. all atoms with an atomic number over 83
Answer:
1. The elephant has more kinetic energy at this speed and mass. It has 4,500 J more KE.
2. The elephant would have to go at a speed of 2.5 m/s to reach the same KE as the cheetah.
Explanation:
You would use the formula KE=1/2mv^2.
This formula would be filled in and completed twice, once for the elephant and once for the cheetah.
Cheetah:
KE = 1/2 (40) (25) ^2
KE = 12,500 J
Elephant:
KE = 1/2 (4,000) (2) ^2
KE = 8,000 J
This shows that the cheetah has more KE.
Then you would subtract the elephants amount of J from the cheetahs to find the difference.
Difference = 12,500 J - 8,000 J
Difference = 4,500 J
I hoped this helped with the first part :)
For the second part:
To find the speed the elephant would have to run you would fill in and complete the equation once more with different distance results.
KE = 1/2 (4,000) (2.5) ^2
KE= 12,500 J
The north celestial pole (and also the south) are described as two imaginary points that project on the axis of rotation of the earth, indefinitely towards space and that intersects with the celestial sphere (Remember that the earth has a slight inclination with respect to to its axis of rotation). The north and south celestial poles are directly above the head of someone located at the north or south pole of the earth.
Correct Answer is A.
