Answer:

<h2><em>1. A sharp knife cuts more effectively than a blunt knife as it has a very small surface area and exerts more pressure. 2. A nail has a pointed edge so that it exerts more thrust or pressure.</em><em> </em><em>are</em><em> </em><em>two example where factor area practcally used to increase pressure</em><em>.</em></h2>

1. A nail has a sharp tip with very less surface area to increase pressure and make it easy to use it.

2. A knife is sharp with less surface area to increase pressure and make it easier to cut.

Because

pressure =  \frac{force}{surface \: area}

What is the speed of an electron that has a de Broglie wavelength of 100. nm?
Advocard [28]

<u>Answer:</u> The speed of the electron is 7.24\times 10^3m/s

<u>Explanation:</u>

To calculate the speed of electron for given wavelength, we use the equation given by De-Broglie's, which is:

\lambda=\frac{h}{mv}

where,

\lambda = De-Broglie's wavelength = 100nm=100\times 10^{-9}m

h = Planck's constant = 6.6\times 10^{-34}Js

m = mass of the electron = 9.11\times 10^{-31}kg

v = speed of the electron = ?

Putting values in above equation, we get:

100\times 10^{-9}m=\frac{6.6\times 10^{-34}Js}{9.11\times 10^{-31}kg\times v}\\\\v=\frac{6.6\times 10^{-34}Js}{9.11\times 10^{-31}kg\times 100\times 10^{-9}m}=7.24\times 10^3m/s

Hence, the speed of the electron is 7.24\times 10^3m/s

a gas that exerts a pressure of 151 mm Hg in a container with a volume of _____ L will exert a pressure of 166 mm Hg when transf
Phoenix [80]
The answer would be using proportions 151/x=166/0.532, then you solve for x. The answer would be <span>0.483927711, but then you have to round it and get approximately 0.484 L. Hope this helps! Happy Studying!</span>
