A scientist weighed an object at two different locations. The first location was Death Valley at about 86 meters below sea level. The second location was Denali at about 6194 meters above sea level. Which observation would the scientist most likely make about the weight of the object in the two locations? Group of answer choices

The weight of the object would be less on Denali because there would be more mass between the object and the center of Earth.

The weight of the object would be less in Death Valley because the temperature is much higher.

The weight of the object would be greater on Denali due to the centripetal forces of the rotation of Earth.

The weight of the object would be greater in Death Valley because it is closer to the center of Earth.

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.  

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
