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>

Answer:
At the surface of the Atlantic Ocean
Explanation:
The atlantic ocean is a worm ocean and the surface has the least dense water. This is because the denser layer of water sinks, while the least dense floats.
The Atlantic Ocean stands out in the choices with warmer temperatures at depths. This results from the different flow dynamics in the semi-enclosed Mediterranean Sea.
Answer:
Required materials for electroplating are - battery or electric supply, cathode, anode and salt solution of material to be coated. Electroplating is the process of releasing ions from electrolytes and coating them as atoms on required material.
Answer:
a) 3.6 sec
b) 17.7 m/s
c) 17.7 m/s
d) 63.6 m
Explanation:
y = (25sin45)t - 4.9t^2 =17.7t - 4.9t^2
a) to find hang time set y = 0
4.9t^2 = 17.7t or t = 3.6 sec
b) vx = 25cos45 = 17.7 m/s
c) vy = 25sin45 = 17.7 m/s
d) To find the range R, use the results in (a) and (b) into the equation R = vxt:
R = (17.7 m/s)(3.6 sec) = 63.6 m
