The answer is A: its amorphous struture
Note that the density of mercury is
(i) 13545 kg/m^3 at 20 deg.C
(ii) 13472 kg/m^3 at 50 deg, C
For a given mass, M kg, by using the volume at 20 deg. C, obtain
M = (13545 kg/m^3)*(0.002 m^3) = 27.09 kg .
Let V m^3 = volume at 50 deg. C
Then
(13472 kg/m^3)*(V m^3) = 27.09 kg
V = 27.09/13472 = 0.002010837 m^3
Answer:
The closest answer is A. 0.002010812 m^3
Answer:
The first questions answer is letter A
S = ut + 0.5at^2
let downward is positive.
s = 0 ; return to the thrower
t = 5.2
a = g = 10 m/s^2 ; downward
you will get u as negative (upward) otherwise something is wrong.
Answer:
B. Seattle has a continental temperature profile, but Miami has a tropical temperature profile.
Explanation:
The statement that best contrasts the climates of Seattle and Miami is Seattle has a continental temperature profile, but Miami has a tropical temperature profile. Seattle is classified as a rainy city, it means that it rains constantly in this place. Miami has a tropical savanna climate, with pleasantly warm winters and long and muggy summers.
