What is an expression of Boyle's law (k = constant)?
Leni [432]

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.

If an object moves in uniform circular motion in a circle of radius R=2.00 meters, and the object takes 5.00 seconds to
Minchanka [31]

Answer:

The centripetal acceleration of the object is 315.5\ m/s^2.  

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 :

\omega=\dfrac{\Delta \theta}{\Delta t}\\\\\omega=\dfrac{2\pi \times 10}{5}\\\\\omega=12.56\ rad/s

The centripetal acceleration of the object is given by :

a=\omega^2 r\\\\a=(12.56)^2 \times 2\\\\a=315.5\ m/s^2

So, the centripetal acceleration of the object is 315.5\ m/s^2.

den301095 [7]
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.
