Answer:
The correct answer is C, which is 9
Explanation:
UP COUNTER
Since the accumulated value is 7, when it increments by two pulses the value of the accumulator increase to 9.
Up counter counts a value from the current value when a signal arrives at the input terminal. There is a reset terminal and preset value too. The counter counts up until the count reaches the preset value and resets. Whenever the input value changes from 0 to 1 the counter increment 1 from the preset value.
The up-counter is an output instruction whose function is to increment its accumulated value on false-to-true transitions of its instruction. It thus can be used to count false-to-true transitions of an input instruction and then trigger an event after a required number of counts or transitions. The up-counter output instruction will increment by 1 each time the counted event occurs.
Answer:
37 psi
Explanation:
For ideal gases this equation applies:
p1*V1/T1 = p2*V2/T2
Since we are assuming volume remains constant:
V2 = V1
p1/T1 = p2/T2
p2 = p1*T2/T1
The temperatures must be in absolute scale.
T1 = 15 + 273 = 288 K
T2 = 60 + 273 = 333 K
Then:
p2 = 32 * 333 / 288 = 37 psi
Answer:
A roller coaster does not have an engine to generate energy. This builds up a supply of potential energy that will be used to go down the hill as the train is pulled by gravity. Then all of that stored energy is released as kinetic energy which is what will get the train to go up the next hill.

Answer:
A) ν = 0.292
B) ν = 0.381
Explanation:
Poisson's ratio = - (Strain in the direction of the load)/(strain in the direction at right angle to the load)
In axial tension, the direction of the load is in the length's direction and the direction at right angle to the load is the side length
Strain = change in length/original length = (Δy)/y or (Δx)/x or (ΔL/L)
A) Strain in the direction of the load = (2.49946 - 2.5)/2.5 = - 0.000216
Strain in the direction at right angle to the load = (7.20532 - 7.2)/7.2 = 0.0007389
Poisson's ratio = - (-0.000216)/(0.0007389) = 0.292
B) Strain in the direction of the load = (2.09929 - 2.1)/2.1 = - 0.0003381
Strain in the direction at right angle to the load = (5.30470 - 5.3)/5.3 = 0.0008868
Poisson's ratio = - (-0.0003381)/(0.0008868) = 0.381
