Answer:
The correct answer is True.
Explanation:
The feedback control system implies that to make a feedback, there must first be an error, otherwise there will be nothing to correct.
This system works so that there is an output that is controlled through a signal.
This signal will be feedback and it will signal an error which will be detected by a controller that will allow entry into the system.
In basic words, this system processes signals, samples them in the form of an output, and re-enters them feedback to detect the error signal.
The classical motion for an oscillator that starts from rest at location x₀ is
x(t) = x₀ cos(ωt)
The probability that the particle is at a particular x at a particular time t
is given by ρ(x, t) = δ(x − x(t)), and we can perform the temporal average
to get the spatial density. Our natural time scale for the averaging is a half
cycle, take t = 0 → π/
ω
Thus,
ρ = 
Limit is 0 to π/ω
We perform the change of variables to allow access to the δ, let y = x₀ cos(ωt) so that
ρ(x) = 
Limit is x₀ to -x₀
Limit is -x₀ to x₀
This has 
as expected. Here the limit is -x₀ to x₀
The expectation value is 0 when the ρ(x) is symmetric, x ρ(x) is asymmetric and the limits of integration are asymmetric.
Answer: d) Prandtl number
Explanation: Prandtl number is basically defined as the ratio between the fluid's viscosity to the thermal conductivity.It doesn't have any sort of dimension. The fluids which are discovered with the small Prandtl numbers are considered as good fluids as they have a smooth rate of flow and as the number increases the fluid are not considered as reliable. Thus,option (d) is the correct option.
Answer:
people die but live geese the answer
Explanation:
The use of smart cranes doesn't enable transportation companies to: B. Manually load or unload crates onto a train with several workers.
<h3>What is a
smart crane?</h3>
A smart crane can be defined as a mechanical equipment that is designed and developed to automatically load, unload, or control the movement of heavy equipment (objects) from one point to another, especially through the use of a projecting arm or beam.
<h3>The use of smart cranes.</h3>
Generally, various transportation companies use a smart crane to achieve and perform the following tasks:
- An ability to hire fewer workers to transport crates onto trains or haulage vehicles.
- An ability to control the movement of heavy objects.
- An ability to incorporate technological advancements into their routine work or daily practices.
Hence, the use of smart cranes by transportation companies completely abolishes the need to manually load or unload crates onto a train with several workers.
