Hi! Hope you're having a great day!
Answer:
The power spectral density of Y(t) is Syy(w) = 
Explanation:
Answer:
The person responsible for the certifications could also be criminally responsible.
Explanation:
In the text above we can notice the variation of the salmonela results tests in which implies that someone deliberately changed the certificates.
The person who emitted the certificates before the tests even been ready indicates an indirect influence on the decision, either through bribery or internal agreements, this shows that they would work in conjunction with Stewart Parnell to release unsafe products.
Answer: they would be 300 miles from the station.
Explanation:
At the point where both trains meet, they would have covered the same distance.
Let t represent the time spent by the first train in covering this distance.
Distance = speed × time
The first train leaves the station and travels north at 60km/hr.
Distance covered by the first train is
60 × t = 60t
Two hours later, a second train leaves on a parallel track and travels north at 100km/hr. Time spent by the second train in covering this distance is (t - 2) hours
Distance covered by the second train is
100(t - 2) = 100t - 200
Since both trains covered the same distance, then
100t - 200 = 60t
100t - 60t = 200
40t = 200
t = 200/40
t = 5 hours
The distance that they would be from the station is
60 × 5 = 300 miles
Answer:
G =67.74
Explanation:
Given that
length l=2.4 m
Outside diameter= 16 cm
Inside diameter= 15 cm
Speed N =900 RPM
We know that
Where r is the radius V is the velocity.
So mean radius
r = 7.5 cm
We know that
V=ω x r
V= 94.24 x 0.075 m/s
V= 7.06 m/s
G =67.74
