Lithium is a metal with an oxidation number of 1+ and oxygen is a nonmetal with an oxidation number of 2-. Which chemical formul
Feliz [49]

The answer is Li2O.

Lithium metal is isolated electrolytically from a mixture of lithium chloride and potassium chloride. The nucleus of the lithium atom verges on instability, since the two stable lithium isotopes found in nature have among the lowest binding energies per nucleon of all stable nuclides.

After fixing a flat tire on a bicycle you give the wheel a spin. Its initial angular speed was 5.40 rad/s and it rotated 12.3 re
zaharov [31]

To solve this problem it is necessary to apply the concepts related to the kinematic equations of angular motion.

By definition, acceleration can be expressed as the change in angular velocity squared over a given period of distance traveled.

\alpha = \frac{\omega^2}{2\theta}

where,

\omega = Angular velocity

\theta = Angular displacement.

In turn, as a function of time, we can represent it as,

\alpha = \frac{\omega}{t}

For our case we have to,

\omega = 5.4rad/s

\theta = 12.3rev = 12.3rev(\frac{2\pi rad}{1rev})=24.6\pi rad

PART A) In the case of angular acceleration we have to,

\alpha = \frac{\omega^2}{2\theta}

\alpha = \frac{(5.4)^2}{2*24.6\pi}

\alpha = 0.1886rad/s^2

PART B) Through the definition of angular acceleration as a function of time we can calculate it,

\alpha = \frac{\omega}{t}

t = \frac{\omega}{\alpha}

t = \frac{5.4}{0.1886}

t = 28.63s
