Answer:

The correct answer is triode.

Explanation:

A vacuum tube is a device that control the flow of electric current between its electrodes in the presence of vacuum. The first vacuum tube which was used have two electrodes and called diode. Then another vacuum tube was invented having a grid between its two electrodes anode and cathode. So, that grid control the flow of electric current between these two electrodes. So, this tube named as triode named as it have one grid and anode and cathode. Other tubes which have more than one grid called according to there number of electrodes totally like tetrode, pentode.

I hope it will help you!

The CMOS battery located on a computer's motherboard allows for maintaining the correct time and date information stored in CMOS
siniylev [52]

Answer:

True                

Explanation:

  • CMOS (complementary metal-oxide-semiconductor) is a chip which is placed on the motherboard in order to store the system date and time and this is powered by a CMOS battery which is housed inside this chip and is used to manage the date and time when the system is off.
  • This is a long lasting battery which can work till the life of a motherboard.
  • This battery is also used to maintain BIOS settings and hardware settings and BIOS uses it during the booting process in order to retrieve the stored information regarding the hardware or system date time.
  • CMOS chip is basically volatile and cannot retain settings information when the computer system powers off but the CMOS battery helps to maintain these setting just like system time and date when the computer gets shut down.

anygoal [31]

Answer:

# the dog dataframe has been loaded as mpr

# select the dogs where Age is greater than 2

greater_than_2 = mpr [mpr. age > 2]

print(greater_than_2)

# select the dogs whose status is equal to 'still missing'

still_missing = mpr[mpr. status == 'Still Missing']

print(still_missing)

# select all dogs whose dog breed is not equal to Poodle

not_poodle = mpr [mpr.breed != 'Poodle']

print(not_poodle)

Explanation:

The pandas dataframe is a tabular data structure that holds data in rows and columns like a spreadsheet. It is used for statistical data analysis and visualization.

The three program statements above use python conditional statements and operators to retrieve rows matching a given value or condition.

return 0;

}

Explanation:

  • Use the built-in rand function to generate a random coin.
  • Get all the required values for quarters, dimes, nickles and pennies and store them in variables.
  • Check if the coins give a value of temp, then answer is correct and the values of user will be added.
  • Optimum solution is displayed  If it does not matches with the optimum solution. Display that the answer is wrong along with solution.
