Answer:
194,22g/mol
Explanation:
8*12,01+10*1,01+4*14,01+2*16=194,22g/mol
It's just 53m
Displacement usually requires a direction but as it specifies to just give magnitude you can just say 53m :)
Answer:
D. A negative externality.
Explanation:
Particulate pollution is a form of pollution that is responsible for the degradation of the environment.
Particulate matter is also referred to as particle pollution or atmospheric aerosol particles and it can be defined as a complex microscopic mixture of liquid droplets and solid particles that are suspended in air.
An externality is typically an unwarranted cost or benefit by a manufacturer or producer of goods and services that affects a third party.
In Economics, an externality could either be positive or negative depending on its effect on a third party.
A negative externality arises when the production or consumption of a finished product or service has negative impact (cost) on a third party.
In conclusion, air pollution is an example of a negative externality because it causes harm to a third party.
The tangential speed of an orbiting object is 
Explanation:
The tangential speed of an orbiting object is defined as the ratio between the distance covered in one revolution and the period of revolution:
where
d is the distance covered during one period
T is the orbital period
However, the distance covered during one period is the circumference of the circle:
where
r is the radius of the circle
Substituting the 2nd equation into the 1st equation, we find:
So, this is the final expression for the tangential speed of an orbiting object.
