What is the name given to the vehicles that warn motorists about oversized loads/vehicles?

The animation shows the circuit inside a speaker. The speaker cone vibrates as the current changes direction. This creates sound

I am Lyosha [343]

Answer:

The direction of the magnetic field around the coil reverses. The force on the cone now pulls it back in. Repeatedly alternating the current direction makes the cone vibrate in and out. The cone vibrations cause pressure variations in the air, which are sound waves.

Explanation:So as it goes back and forth it makes a sound from the vibration.

Technician A says some coolant recovery systems are pressurized. Technician B says the coolant recovery system is used to keep a

Digiron [165]

Answer: Technician A

Explanation: A coolant recovery system Is one of the most important part of a vehicles cooling system. When a coolant gets too hot, it forces it way out of the spring loaded radiator cap so as to relieve pressure. Any coolant which has escaped is recovered back through the discharge tube located in the recovery tank. The system is usually air free

4.In a hydroelectric power plant, 100 m3/s of water flows from an elevation of 120 m to a turbine, where electric power is gener

Dmitrij [34]

Answer:

The rate of irreversible loss will be "55.22 MW".

Explanation:

The given values are:

Elevation,

h = 120 m

Flow of water,

Q = 100 m³/s

Efficiency,

= 80%

i.e,

= 0.8

Efficiency turbine,

= 50 MW

Now,

Without any loss,

The power generated by turbine will be:

⇒ $P=\delta gQh$

On substituting the values, we get

⇒ $=1000\times 9.8\times 100\times 120$

⇒ $=117.72 \ MW$

Power generated in actual will be:

= $\frac{50}{0.8}$

= $62.5 \ MW$

Hence,

Throughout the piping system,

The rate of irreversible loss is:

= $Power \ generated \ by \ turbine-Power \ generated \ in \ actual$

= $117.72-62.5$

= $55.22 \ MW$

Danny is looking at deploying a new application that requires root-level access to the server. He is currently researching the c

Advocard [28]

Answer:

Option C (IaaS) will be the correct answer.

Explanation:

IaaS is essentially a cloud strategy that enables an individual or company to rent resources including such servers, networking devices including data or storage management. IaaS is a digital storage facility.
PaaS can not provide root privileges as even the hosting company would control the network. Here, SaaS as well as DBaaS aren't important.

That will be the right answer to the question.

Write a Pig script and run it in local mode on this data to find out the top 10 states according to the land area. Since you wan

ELEN [110]

Explanation:

Apache Pig script execution modes

Local mode: In 'local mode', you can run the pig script on the local file system. In this case, you don't need to store the data in the Hadoop HDFS file system, instead you can work with the data stored in the local file system.

MapReduce mode: In 'MapReduce mode', the data must be stored in the HDFS file system and you can process the data with the help of pig script.

Apache Pig Script in MapReduce mode

Let's say our task is to read data from a data file and display the required contents in the terminal as output.

The sample data file contains the following data:

Txt information file - Apache Pig Script - Edureka

Save the text file with the name 'information.txt'

The sample data file contains five First Name, Last Name, Mobile Number, City, and Profession columns separated by the tab key. Our task is to read the contents of this HDFS file and display all the columns of these records.

To process this data using Pig, this file must be present in Apache Hadoop HDFS.

Command: hadoop fs –copyFromLocal /home/edureka/information.txt / edureka
