<em>Explanation:</em>
<em>The Atmosphere contains all of the planets air, And without air we can't breathe so I think this would be a good answer for you to choose, have a nice day</em>
Answer:
0.02
Explanation:
coefficient of kinetic friction = μ
force of friction = Ff
Normal Force = FN, but
FN = -W
Ff = -μFN
so μ = Ff/FN
= 4N/200N
= 0.02.
The formula for the density of a substance expressed in mass and volume is rho = mass/volume or p = m/v. Rearranging the formula to isolate volume gives the formula v = m/p. To solve for the problem given, this formula must be used. This gives a solution of:
v = m/p = 250 g/ 968 g/cm^3 = 0.258 cm^3 of sodium
Answer:
107 °F
Explanation:
Given that
The temperature at sea level = 100°F
height ,h= 2000 feet
The average lapse rate = 3.5°F/1000 feet
Given that rise in temperature 3.5°F per 1000 feet.
1000 feet ⇒ 3.5°F
Given that 2000 feet
2000 feet ⇒ 3.5°F x 2 +100°F
2000 feet ⇒ 107 °F
Therefore the temperature will be 107 °F .
I'm pretty sure it would be 4 because the first two times to goes around would be 3 hours plus another two times to make 3 more hours making the amount of times it orbited Earth 4
