7. An electron moves at 3.0 x 107 meters per second perpendicularly to a magnetic field that has a flux density
of 2.0 teslas. What is the magnitude of the force on the
electron?
A. 9.6 x 10-19 N
B. 3.2 x 10-19 N
C. 9.6 x 10-12 N
D. 4.8 x 10-12 N

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

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!

a is the best answer your welcome
