Stabilizer with area = 14 cm2
Explanation:
i dont know why but its right
Answer:
P.E.T
Explanation:
Stud is a short form of stud wall which are typically vertical framing members in a wall of a building. Wall studs are available in standard lengths but since the height of ceiling vary, sometimes one has to cut the stud walls on site to fit. Therefore, there are pre-cut studs which are more efficient in implementation. These are usually referred as Precision-End Trimmed studs, (P.E.T). Therefore, stud walls which are cut to exact length at the mill for modern construction are designated by letters P.E.T
Answer:
1. Graph C
2. Friction
Explanation:
1. The line on all of the graphs shown represents velocity. The formula for velocity is 
where d is distance and t is time. Focusing on the first lap, the starting point on the graph should be the origin and the "ending" point should be (20, 3). These requirements eliminate graph A as an answer because its "end" is not (20, 3). During the break, the student does not move, so the slope of the line should be completely horizontal. The break lasted for 5 minutes, so the correct graph should have a horizontal line between the points (20, 3) and (25, 3). This requirement eliminates graph B and D because their break is either not long enough (B) or too long (D).
2. Friction slows down the movement of objects. When an object is rough, it produces more friction which causes the object to be slowed more. When an object is smooth, friction slows it less than it would for a rough object.
Answer:
Explanation:
From the given information:
Strain fracture toughness 
= 75 MPa
Tensile stress 
= 361 MPa
Value of Y = 1.03
Thus, the minimum length of the critical interior surface crack which will result to fracture can be determined by using the formula:
![a_c = \dfrac{1}{\pi} ( \dfrac{k_k}{\sigma Y})^2 \\ \\ a_c = \dfrac{1}{\pi} \Big [ \dfrac{75 \times \sqrt{10^3}}{361 \times 1.03 } \Big]^2 \\ \\ a_c = \dfrac{1}{\pi} \Big [ 6.378474693\Big]^2 \\ \\ \mathbf{ a_c = 12.95 \ mm}](https://tex.z-dn.net/?f=a_c%20%3D%20%5Cdfrac%7B1%7D%7B%5Cpi%7D%20%28%20%5Cdfrac%7Bk_k%7D%7B%5Csigma%20Y%7D%29%5E2%20%5C%5C%20%5C%5C%20%20a_c%20%3D%20%5Cdfrac%7B1%7D%7B%5Cpi%7D%20%5CBig%20%5B%20%5Cdfrac%7B75%20%5Ctimes%20%5Csqrt%7B10%5E3%7D%7D%7B361%20%5Ctimes%201.03%20%7D%20%5CBig%5D%5E2%20%5C%5C%20%5C%5C%20%20a_c%20%3D%20%5Cdfrac%7B1%7D%7B%5Cpi%7D%20%5CBig%20%5B%206.378474693%5CBig%5D%5E2%20%20%5C%5C%20%5C%5C%20%5Cmathbf%7B%20a_c%20%3D%2012.95%20%5C%20mm%7D)
