What is the magnetic force on a proton that is moving at 5.2 x 10^7 m/s to the left through a magnetic field that is 2.4 T and pointing toward you? The charge on a proton is 1.6 x 10^-19 C.
A. 2.0 x 10^-11 N down
B. 2.0 x 10^-11 N up
C. 8.3 x 10^-12 N up
D. 8.3 x 10^-12 N down

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!

the answer is 100. i just did this lesson and got a 100% on it. : )
