Answer:

Option (3) is the correct answer of this question.

Explanation:

HCatalog makes available Hive metadata to users of other Hadoop applications, such as Pig, MapReduce and Hive. it offers interfaces for MapReduce and Pig so that users can read data from and write data to the Hive warehouse.
This means users don't have to care about where or in what format their data is stored. So we know this way that Hcatalog makes sure our data is secure.
Others option does not belong to Hcatalog so these options are incorrect .

Acceleration is the rate at which an object changes its velocity. It is typically represented by symbol a and measured in m/s2 (

Natalija [7]

Answer:

Pseudocode:

INPUT velocity

INPUT time

SET velocity = 0.44704 * velocity

SET acceleration = velocity / time

SET acceleration = round(acceleration, 1)

PRINT acceleration

Code:

velocity = float(input("Enter a velocity in miles per hour: "))

time = float(input("Enter a time in seconds: "))

velocity = 0.44704 * velocity

acceleration = velocity / time

acceleration = round(acceleration, 1)

print("The acceleration is {:.2f}".format(acceleration))

Explanation:

*The code is in Python.

Ask the user to enter the velocity and time

Convert the miles per hour to meters per second

Calculate the acceleration using the formula

Round the acceleration to one decimal using round() method

Print the acceleration with two decimal digits

I have used a C++ data structure or collection called Maps for the solution to the question.

Maps is part of STL in C++. It stores key value pairs as an element. And is perfect for the task at hand.
