A student wants to make a very small particle accelerator using a 9 V battery. What speed will a proton have after being accelerated from rest through the 9 V potential difference? What speed will an electron have after being accelerated from rest through the 9 V potential difference?

v = 4.15 10⁴ m / s

Explanation:

Suppose that all the energy in the battery is converted into kinetic energy of the proton

            U = K

           q V = ½ m v²

            v = √ 2q V/m

            v = √ (2  1.6 10⁻¹⁹ /1.67 10⁻²⁷  9)

            v = √( 17.2455 10⁸)

            v = 4.15 10⁴ m / s

Relativistic corrections are not needed as this speed is much less than the speed of light

the force required to move the cart is divided by three or 33.33 n.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
