Pllllllllllllllllllssssssssss help me will give brainiest if correct

I believe it is the same as before-Electrical energy is transformed into heat and light energy.

Explanation:

Hope this helps'-'

Chemical energy (in his muscles) ===> kinetic energy ===> electrical energy ===> light energy and a little bit of heat energy

30 fN ( 30* 10^-15 N) and it is pointed to to -y-axis.

Explanation: In order tosolve this question we have to usethe Coulomb force given by:

F=e*E= 1.6 *10^-19 C* 1920 N/C= 30 fN the force pints in opossite direction of the electric field due to the sign of charge of the electron.
