Will mark brainliest to the first person who gets it right. 17. figure a-10 shows the back of a typical bottle of engine oil. the label indicates that this oil is sae 10w-30, with a classification of sh, sg/cd. based on the information printed on the label, which of the following statements is true? a. this is a multiviscosity oil with a weight of 10 that's designed for use in 1991 and later model engines, as well as in supercharged diesel engines. b. this is a single-viscosity oil with a weight of 10 that's designed for use in 1991-1993 engines, as well as in moderate-duty diesel engines. c. this is a multiviscosity oil with a weight of 30 that's designed for use in 1991 and later model engines, as well as in naturally aspirated diesel engines. d. this is a single-viscosity oil with a weight of 30 that's designed for use in 1980-1990 cars and light trucks, as well as in light-duty diesel engines.

Write a car class having two private member variables called tank and speed. write public methods called pumpgas and gofast. the method pumpgas gets an integer for gas that must be pumped. that value needs to be added to tank (no more than 20 gallons). it must return the amount of gas that is purchased ($4 per gallon). the method gofast should increase the speed by 5 each time it is called. write a constructor for the above class that initialized both variables to zero. write a tostring to display both the tank and speed when the car is printed. modify the car class to implement the interface comparable and an interface called carinter having the public methods in carinter. write the main program to create an array of size 5 of type car. create 5 car objects having each location of the array to refer to one of the cars. test the pumpgas, gofast, equals method on the array items. write an enhanced loop to print all the car values (using a tostring written last time).write a generic method to find the minimum of four items. pass int, double, char, string and car objects to test this method.

Creating "smart interfaces" in all sectors of industry, government, and the public arena is one of the fastest growing hct areas. these interfaces model, interpret, and analyze such human characteristics as speech, gesture, and vision. the field of biometrics, in which humans authenticate themselves to machines, is an area of considerable interest to hct practitioners. fingerprint scans are one of the most frequently used biometric options, and this article, biometric student identification: practical solutions for accountability & security in schools, makes a case for the implementation of fingerprint scans in schools. critique the article, and answer the following questions: according to the author, what are the main benefits of adopting fingerprint scans in schools for student identification? according to the author, what are the main drawbacks of adopting fingerprint scans in schools for student identification? do you agree with the author's assessment of the pl
