Answer:
B: Bind
Explanation:
JavaFX property binding permits the synchronization of the value of two properties in such a way that whenever there is a change in one of the properties, there is an immediate update on the value of the other property. In this way, The StringProperty method bind receives an ObservableValue as an argument. When the ObservableValue changes, the bound property is updated accordingly.

Answer:
a. Convenience
b. Random
c. Stratified
d. Systematic
Explanation:
Types of sampling:
The selection of sample is arbitrary and each member has an equal chance of selection.
This selection does not take probability of selection into account rather focuses on the convenience and proximity of the member for selection.
An ordered system is decided to choose the members for this sample.
This sampling plan divided the population into groups, called clusters. A cluster is then randomly selected from the selected population.
The members of the population are divided into groups, called strata. A random sample is drawn from each strata.
Answer:
CT = 470nF + 1000nF = 1470nF or 1.47μF
Explanation:
When capacitors are connected together in parallel the total or equivalent capacitance, CT in the circuit is equal to the sum of all the individual capacitors added together. This is because the top plate of capacitor, C1 is connected to the top plate of C2 which is connected to the top plate of C3 and so on. The same is also true of the capacitors bottom plates. Then it is the same as if the three sets of plates were touching each other and equal to one large single plate thereby increasing the effective plate area in m2.
Since capacitance, C is related to plate area ( C = ε(A/d) ) the capacitance value of the combination will also increase. Then the total capacitance value of the capacitors connected together in parallel is actually calculated by adding the plate area together. In other words, the total capacitance is equal to the sum of all the individual capacitance’s in parallel. You may have noticed that the total capacitance of parallel capacitors is found in the same way as the total resistance of series resistors.
The currents flowing through each capacitor and as we saw in the previous tutorial are related to the voltage.
