Answer:
Follows are the matching to this question:
Explanation:
Column A Column B
1 c
2 d
3 b
4 a
Description of the matching:
- In 1(Acid) the correct choice is (c) because the acid (HCl) dissociates to both the H+ ion and the Cl- ion as a solution.
- In 2(Alkaline ) the correct choice is (d) because alkaline NaOH is a solution that differentiates between the ions ( OH-) and Na+.
- In 3(pH ) the correct choice is (b) because for an A compound of less than 7 is an acid and an alkaline pH compound of more than 7. For neutral compounds, a pH of 7 is applicable.
- In 4(Ion) the correct choice is (a) because Na+ ion is loaded positive, and Cl-ion is loaded negatively.
Answer:
Base band
: A list of radio frequencies
PRI
: The chip that controls the radio frequency waves within a device
PRL: The connection between a mobile device and radio tower
Explanation:
Base-band is the range or band of frequencies. It contains a number of between upper and lower limit of the frequency. For example if the range of transmission of the signal is 2khz to 3khz. The frequencies between this range are called base band.
PRI is the chip that is used to control the different frequencies received at the device. This chip control the radio frequencies that are allowed to the devices. It is the short form of primary rate interface.
PRL is the list named as Preferred Roaming List. It has stored the information of the mobile devices that are connected to the mobile phone. This list is used while communicating between mobile device and tower.
