This is a guess, but I think it could be the lack of limiting factors.
Kinetic energy=Ek
Ek=(1/2)mv²
Ek=480 J
v=8 m/s
mass=?
Ek=(1/2)mv²
480 J=(1/2)m(8 m/s)²
480 J=(32 m²/s²) m
m=(480 J)/(32 m²/s²)=15 kg
answer: the mass of the object is 15 kilograms.
Explanation:
The boiling point of a substance is 293°C.
The boiling point is the temperature at which the vapor pressure of a liquid becomes equal to the atmospheric pressure.
So, at the boiling point:
The vapor pressure =atmospheric pressure = 1 atm.
To get the vapor pressure of the substance at 220°C is definitely less than 1 atm.
Since, as the temperature increases, the vapor pressure of the liquid increases.
Answer:
Bases
Explanation:
Most soaps fall under the base category as they are slippery and will taste bitter if you taste it (DONT TRY IT THO).
Material C. the less dense is easier to move through than the more dense, so the light moves faster. Its like light moving through less dense glass, then moving through a more dense wall.
