Answer:
3054.32618 rad/s²
-431.1989 rad/s²
29080
Explanation:
Converting angular speed to rad/s
The average acceleration while speeding up is 3054.32618 rad/s²
The number of turns in the 1.2 seconds
The number of rotations in the 1.2 seconds is 349.99
Number of rotations in the 45 seconds
Average angular acceleration while slowing down -431.1989 rad/s²
Number of rotations while slowing down is 2479.16718
Total number of rotations is 349.99+26250+2479.16718 = 29079.15718 = 29080
Answer:
Technician b is correct.
Explanation:
Crimping cable allows a firm connection in mechanical terms and allows a low resistance path for the signal or the current flow, solder although it is better in terms of electrical conduction, can be impractical if the cable is subjected to excessive movement.
A crimped cable with excessive movement can also be easily broken at the ends, where it joins the part of the cable that is crimped, for this reason, a cable that is in excessive motion is recomended to be spliced by joining cable with cable
.
In order to decide which metod is better for splicing cables its necessary to evaluate each situation separatly.
Speed is defined as distance over time. So, since it traveled 100m in 25 sec, the speed was 100 / 25 = 4 m/s.
I got A it was the same question to. Guess its a different answer for every one
The answer is a.
The graph's line is higher if velocity is higher, and lower if velocity is lower. This is because the y axis is velocity. Thus, the fastest (highest velocity) that the car went is when the line was highest, and that is when x is 1.
