Answer:
Explanation:
Given that:
x(t) = 10 sin(10t) . sin (15t)
the objective is to find the power and the rms value of the following signal square.
Recall that:
sin (A + B) + sin(A - B) = 2 sin A.cos B
x(t) = 10 sin(15t) . cos (10t)
x(t) = 5(2 sin (15t). cos (10t))
x(t) = 5 × ( sin (15t + 10t) + sin (15t-10t)
x(t) = 5sin(25 t) + 5 sin (5t)
From the knowledge of sinusoidial signal Asin (ωt), Power can be expressed as:
For the number of sinosoidial signals;
Power can be expressed as:
As such,
For x(t), Power 
For the number of sinosoidial signals;
For x(t), the RMS value is as follows:
The example of a subsystem and system relationship is option
A) mechanical toggle, Xbox controller
Explanation:
- Controls and Controllers are known as the mechanical, electro-mechanical, or electronic devices which are used to input signals to change the conditions or values which are in processes or access to buildings, operators, gated areas, etc.
- When you press and hold the given Shift button, these buttons which are chosen becomes an alternate inputs.
- Normally, there are three controllers(PID) which are used in any of the process industries inorder to maintain and control the required setpoint.
- an example of a subsystem and system relationship is a mechanical toggle, Xbox controller
- Controllers improve the steadiness and state of accuracy by decreasing the steady state error. When the steady state accuracy gets better, the stability also improves.
- Controllers are also used to help in reducing the unwanted offsets which are produced by the system.
Answer:
1) titration
2) titrand
3) equivalence point
4) titrant
5) Burette
6) Indicator
Explanation:
The process of adding a known volume a standard solution to another solution to react with it in order to determine the concentration of the unknown solution is known as titration.
The solution to which another solution of known concentration is added is called the titrand while the solution of known concentration is called the titrant.
A burette is a glassware used to slowly add a known volume of the titrant to the titrand. An indicator shows the point when the reaction is complete by a color change. This is the point when the required amount of one solution has been added to the second solution. It is also called the equivalence point.
Answer:
vertical, and directed along an axis of symmetry of the cross-section
Explanation:
Shear is a force in an object is in the form of stress or strain. Shear strain is the ratio of length of deformation (extension) to the perpendicular length in the plane of the force applied. Shear stress, which is the stress that tends to shear a material, is the ratio of shear force applied on a surface to the area of the surface.
The shear formula can be used to determine the maximum shear in an object and is given by; τ = 
. It is applicable when the internal shear force is vertical and directed along an axis of symmetry of the cross-section.
