Answer:

radioactive decay is a random process
use long tongs

Explanation:

Quantum theory has taught us that virtually everything to do with the nature of matter in the universe is a random process. The decay of atomic nuclei is something that makes that randomness "visible" with appropriate instrumentation. As such, the rate of decay will vary over the "short" term. Consequently, it is not surprising to see a variation of a few counts in an activity measurement over a period of a few minutes.

Safety with respect to radioactive materials involves staying as far away from them as possible. The use of long tongs for handling would be appropriate.

The average distance between collisions for atoms in a real gas is known as the mean free path (see pp. 298-9 in McKay). Which o

dusya [7]

Answer:

300 nm

Explanation:

R = Gas constant = 8.314 J/molK

r = Atomic radii = $1\times 10^{-10}\ m$

d = Atomic diameter = $2r=2\times 10^{-10}\ m$

At STP

T = Temperature = 273.15 K

P = Pressure = 100 kPa

$N_A$ = Avogadro's number = $6.022\times 10^{23}$

The mean free path is given by

$\lambda=\frac{RT}{\sqrt2d^2N_AP}\\\Rightarrow \lambda=\frac{8.314\times 273.15}{\sqrt2 \pi \times (2\times 10^{-10})^2\times 6.022\times 10^{23}\times 100000}\\\Rightarrow \lambda=2.12165\times 10^{-7}\ m=212.165\times 10^{-9}\ m=212.165\ nm$

The answer that best represents the mean free path for gas molecules is 300 nm

victus00 [196]

Answer:

The equation for momentum of a piece of matter.

In either case, the momentum would be less than a linebacker hitting you at full speed. The equation for momentum is written: p = mv where p stands for momentum. That is, mass times velocity equals momentum.
