Answer:
C.) PV = k
Explanation:
Boyle's Law is a variation of the Ideal Gas Law when all variables, except for pressure and volume, are held constant.
Pressure is represented by "P" and volume is represented by "V". In the Ideal Gas Law, pressure and volume are inversely proportional (if one goes up, the other goes down). That being said, the equation which best represents Boyle's Law is PV = k.
Different colors of sedimentary rock are determined by the environment where they are located. For example, red rocks form where oxygen is present. Darker sediments form when the environment is oxygen poor.
So, basically, the weather and surroundings of the rock, so B.
Answer:
The centripetal acceleration of the object is 
.
Explanation:
We have,
Radius of a circular path is 2 m
It takes 5 seconds to complete 10 revolutions. It means its angular velocity is :
The centripetal acceleration of the object is given by :
So, the centripetal acceleration of the object is .
I think answer youre looking for is 2Na+O->Na2O . But sadly it is wrong since we dont use atomic oxygen in reactions. It should be rather
4Na+O2 => 2Na2O but it doesnt correspond to ratios given.
