Answer:
Explanation:
Given Preception time = 1.0 sec
Deceleration rate = 11 ft /sec2
Interpretation rate as = 3words /sec
The board consists of “WORK ZONE: 20 MPH SPEED ZONE”
Then Interpretation time = 2.0 sec
Decision time = 0.5 sec
Assume that the vehicle was traveling with 65mph
Perception Time
So, if you’re driving at 65 mph, your vehicle will travel 71 feet before you realize you need to start braking.
Reaction Distance
At 65 mph, that’s another 71 feet traveled.
Braking Distance
At 65 mph, it takes an additional 5.5 seconds or about 525 feet of actual brake application to stop your vehicle.
Stopping Distance
To determine the stopping distance, you calculate: Perception Distance (71 feet) + Reaction Distance (71 feet) + Braking Distance (525 feet) = Stopping Distance (667 feet)
Then to reduce the speed it takes 7.0 secs
Answer:
“I really love the design work in engineering, the face-to-face interaction with clients, and the opportunity to see projects come to life. But if I had to pick one thing that I don’t enjoy as much, I would have to say it’s contract preparation.”
Answer:
Bubble sort, sometimes referred to as sinking sort, is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order. The pass through the list is repeated until the list is sorted

Answer:
Explanation:
Given data:
T_1 = 55 degree F
t_2 - 25 degree F
COP = 2.45
Production rate = 28 lbm/h
we knwo that cooling load is given
Power is determined as
Answer:
150 N
Explanation:
Moment is the product of force and distance:
27 N·m = F·(0.180 m)
F = 27 N·m/(0.180 m) = 150 N
The force required to produce the desired moment is 150 N.
