Answer:
Condensation.
Explanation:
The boiling point of water is much higher than that of either nitrogen or oxygen gas . So when the mixture is condensed to a temperature lower than
100°C , water vapor will come out first in the form of water leaving other
elements of mixture in gaseous phase. In this way, water vapor will get separated from others.
GREAT QUESTION! Cool subject to talk about :) Here goes nothing lol
1) Apache- North American Indians of the Southwest who fought against frontiersmen.
2) Arapaho- North American Plains Indians living along the Platte and Arkansas Rivers.
3) Sam Bass- A desperado whose career inspired ballads.
4) Judge Roy Bean- a legendary frontier judge who ruled by one book and a six-shooter!
5) Colt .45 six-shot revolver invented by Samuel Colt and used throughout the West... extremely popular among cowboys and outlaws alike.
6) Last but definetily not last, "Billy the Kid" (William H. Bonney, 1859-1881) Brooklyn-born gunman of the Wild West. Legendary Outlaw.
There are plenty more facts to talk about but in the interest of time this all I can provide for now. Hope it helps and have a nice day/night :)
Answer:
(C) T
The tension T at equilibrium will be equal to the Buoyant force.
The Buoyant force is given by:
Fb = density x acceleration due to gravity x volume displaced
The change in height doesn't affect the Buoyant force and hence the tension.

Answer:
2.46 W
Explanation:
Thermal conductivity k = 53.4 W/m-K
Radius r = 12 mm = 12x10^-3 m
Lenght = 2.5 m
T1 = 361 °C
T2 = 105 ∘C
Area A = ¶r^2 = 3.142 x (12x10^-3)^2
= 0.00045 m^2
Power P = -AkdT/dx
Where dT = 361 - 105 = 256
dx = lenght of heat travel = 2.5 m
P = -0.00045 X 53.4 X (256/2.5)
= -0.024 X 102.4 = -2.46 W
The negative sign indicates that heat is lost from the metal.
Answer:
Explanation:
Kinetic energy is given by the following equation:
, where 
is mass in 
and 
is velocity in 
.
Since the cell phone's mass is given in grams, we need to convert this into kilograms:
.
Therefore, the kinetic energy of the cell phone is:
.
