Answer:
mass and distance
Explanation:
the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases
Three tiny kinds of particles called subatomic particles: protons, neutrons, and electrons.
An element is made up of only one type of atom.
Answer:
126.73 mL
Explanation:
The total pressure of the gas mixture is the sum of the vapor pressure of its constituents. So, the vapor pressure of N₂O(p) can be calculated:
750 = 18.85 + p
p = 750 - 18.85
p = 731.15 torr
It means that for 731.15 torr, N₂O occupied 130 mL. For the general gas equation, we know that
Where <em>p</em> is the pressure, <em>V</em> is the volume, <em>T</em> is the temperature, 1 is the initial state, and 2 the final state. For the same temperatue (21ºC), the equation results on Boyle's law:
p1V1 = p2V2, so:
731.15x130 = 750xV2
750V2 = 95049.5
V2 = 126.73 mL

Hope this helps mate good luck on whatever ur doing
Weather is the day-to-day state of the atmosphere, and its short-term variation in minutes to weeks. People generally think of weather as the combination of temperature, humidity, precipitation, cloudiness, visibility, and wind. Climate is the weather of a place averaged over a period of time, often 30 years.
Weather definitely influences climate because the climate is based on the weather. So if the weather over a long period of time(30 years) increases or decreases, the climate will increase or decrease. Then, the climate has changed
