b. A super class is object is a subclass object.

c. The class following the extends keyword in a class declaration is that direct super class of the class being declared.

d. Java uses interfaces to provide the benefits of multiple inheritance

The derived class is the sub-class and it is derived from its super class, as a matter of fact in Java programming language, all classes are derived from some other class. Objects are made from classes with their state (fields) and behavior (methods) since objects are made from classes, the objects of the super class will not be the same as that of the subclass.

A signal travels from point A to point B. At point A, the signal power is 100 W. At point B, the power is 90 W. What is the atte
11Alexandr11 [23.1K]

Answer:

Attenuation = 0.458\ db

Explanation:

Given

Power at point A = 100W

Power at point B = 90W

Required

Determine the attenuation in decibels

Attenuation is calculated using the following formula

Attenuation = 10Log_{10}\frac{P_s}{P_d}

Where P_s = Power\ Input and P_d  = Power\ output

P_s = 100W

P_d = 90W

Substitute these values in the given formula

Attenuation = 10Log_{10}\frac{P_s}{P_d}

Attenuation = 10Log_{10}\frac{100}{90}

Attenuation = 10 * 0.04575749056

Attenuation = 0.4575749056

Attenuation = 0.458\ db <em>(Approximated)</em>

Mila [183]

Answer:

There is a need for some people to see the total transparency of the records that are meant to be shared with a select group of people. There are certain things that can be done for this. The first one is that the sharing rules should be checked. To whom are the details shared with. The next one is the filters that are used.

These can be reported and changed accordingly. Lastly, the whole organization’s defaults can be checked. This is something that can be done when the previous methods that were done did not work that well. Once some changes are done, the people can check if they already work and if the records can be viewed.
