Using a JS console when using the following code:
const person = {
age: 20,
name: "Ben"
};
const peopleArray = [person, person, person];
peopleArray[1].name = 'Joe';
console.log(peopleArray[0].name); (Returns: Joe)
This ones tricky.
Assuming your windows 10, it's 16 characters but you can type up to 127.
Given Information:
Qin = 8*10 = 80 W
Win = 25 W
Temperature = T2-T1 = 10°C
Required Information:
(a) flow rate of the air = m = ?
(b) fraction of the temperature rise of air = f = ?
Answer:
(a) flow rate of the air m = 0.01044 kg/s
(b) fraction of the temperature rise of air f = 23.8 %
Solution:
(a) The flow rate of the air that fan needs to deliver can be found by
Where the value of specific heat of air is 1005 j/kg.C
m = (80 + 25)/1005*10
m = 0.01044 kg/s
(b) fraction of the temperature rise of air due to fan
ΔT = Q/mCp
ΔT = 25/0.01044*1005
ΔT = 2.38°C
So the fan causes a temperature rise of 2.38°C
f = ΔT/T2-T1
f = 2.38/10
f = 0.238 = 23.8 %

Answer:
It is necessary to acknowledge the SYN and FIN, so the sequence number is incremented, if not the FIN would be seen as a data packet prior an awaited FIN.
Explanation:
TCP or transmission control protocol is a transport layer protocol of the OSI network model in networking. Unlike UDP or user datagram protocol, it is connection oriented, meaning it must establish a connection between both destination and source in the network.
It uses a three way handshake to establish and close connection after transmission. After the SYN packet is acknowledged, the sequence number of the data packet increases to the last and finally increases to a FIN packet to show the end of transmission.
