Electrons are very emotional and compulsive things. They feel
an intense desire to get away from negatively charged things or
places, and an equally strong desire to get closer to positively
charged ones, as if according to some law of nature.
By means of chemical things inside batteries that I don't understand,
one end of the battery is kept positively charged and the other one
negatively charged. So if there's anything between the terminals that
an electron can easily flow through, they'll do it !
With another person on student A’s side. I’m sorry if I wasn’t able to help. Im trying my best from the information given. :)
Thank you for posting your question here at brainly. Below is the answer:
sum of Mc = 0 = -Ay(4.2 + 3cos(59)) + (275)(2.1 + 3cos(59)) + M
<span>- Ay = (M + (275*(2.1 + 3cos(59)))/(4.2 + 3cos(59)) </span>
<span>sum of Ma = 0 = (-275)(2.1) - Cy(4.2 + 3cos(59)) + M </span>
<span>- Cy = (M - (275*2.1))/(4.2 + 3cos(59)) </span>
<span>Ay + Cy = 275 = ((M+1002.41)+(M-577.5))/(5.745) </span>
<span>= (2M + 424.91)/(5.745) </span>
<span>M = ((275*5.745) - 424.91)/2 </span>
<span>= 577.483 which rounds off to 577 </span>
<span>Is it maybe supposed to be Ay - Cy = 275</span>
