We know that E = 0.5mv^2 = hc/(lambda), where lambda is the de broglie wavelength. E = 0.5mv^2 due to the speed that the alpha particle possess in the form of kinetic energy. Hope this helps!

What does the simplified model of the hall effect give for the density of free electrons in the unknown metal?
evablogger [386]
The simplified model of the hall effect proved that the current (electric) in metals are carried by electrons and not protons. The hall effect introduced the hall coefficient which is the ratio of the induced electric field to the current density x applied magnetic field. This coefficient is unique for each type of metal.

10. Carbon tetrachloride has a density of 1.60 g/mL. What is the volume of 40 grams of CCl4?
ikadub [295]

Answer:

The answer is

<h2>25 mL</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density}

From the question

mass of CCl4 = 40g

Density = 1.6 g/mL

The volume is

volume =  \frac{40}{1.6}

We have the final answer as

<h3>25 mL</h3>

Hope this helps you
