Answer:

One battery, two resistors, two switches, three light bulbs

Explanation:

Each component is indicated with the following symbols:

- Battery: it is the one on the right, consisting of two longer lines and two shorter lines. It is the device that provides the electromotive force to the circuit

- Resistors: they are the devices on the bottom line, consisting of zig-zag lines. Resistors are pieces of circuit that resist to the flow of current in the circuit.

- Switches: they are labelled with a line with two dots at both ends. They can be opened/closed in order to stop/allow the flow of current in the circuit.

- Light bulbs: they are labelled with a circle filled with a X.

From what height must an oxygen molecule fall in a vacuum so that its kinetic energy at the bottom equals the average energy of

alexandr1967 [171]

Answer:

The value is $h = 11930 \ m$

Explanation:

From the question we are told that

The temperature is $T = 300 \ K$

Generally the root mean square speed of the oxygen molecules is mathematically represented as

$v = \sqrt{\frac{3 * R * T }{M} } = \sqrt{ 2 * g * h }$

Here R is the gas constant with a value $R = 8.314 \ J\cdot K^{-1} \cdot \ mol^{-1}$

M is the molar mass of oxygen molecule with value $M = 0.032 \ kg /mol$

$\frac{3 * 8.314 * 300 }{0.032} = 2 * 9.8 * h$

=> $h = 11930 \ m$
