When the sun is overhead, light rays pass through less atmosphere, so less UV radiation is screened out. A solar cooker works like a one-way lobster trap. It lets UV light rays in and then converts them to longer infrared light rays that can't escape.

Answer:

A sort of solar thermal collector is a solar cooker. It "collects" and retains the thermal (heat) energy of the Sun. When high frequency light (visible and ultraviolet) is transformed into low frequency infrared radiation, heat is created.

What are the three general methods for delivering content from a server to a client across a network
Tju [1.3M]

Answer:

Answered below.

Explanation:

The three general methods consist of unicasting, broadcasting and multicasting.

Casting implies the transfer of data from one computer (sender) to another (recipient).

Unicasting is the transfer of data from a single sender to a single recipient.

Broadcasting deals with the transfer of data from one sender to many recipients.

Multicasting defines the transfer of data from more than one sender to more than one recipients.

You have a notebook computer and wish to connect to an IEEE 802.11n wireless network. The computer does not have a built-in wire
Ira Lisetskai [31]

Answer:

The wireless adapter to use is the Wireless USB 2.0 Extender

Explanation:

The Wireless USB 2.0 Extender is a USB component that enables a computer to connect to and communicate with other computers on a network, or even to connect to the internet.

It uses an IEEE 802.11g radio platform and communicates within a radio frequency range of 2.4GHz.

Therefore, in cases where a notebook computer does not have a built-in wireless LAN card or PC card interface, you can use the Wireless USB 2.0 Extender as the best solution to that problem.

The computer system operation follows certain principles, some of which are:

1. It makes use of the OPERATING SYSTEM to link the hardware and the software together, without it, the computer system is useless.

2. It works with INPUT DEVICES such as keyboards or stylus. Without input devices, there is no way humans can communicate with the computer system

3. It works with OUTPUT DEVICES such as monitors and speakers. Without output devices, there is no way computers can communicate or give back information to humans.

4. It works with the NETWORK such as LAN or WIFI to provides the sharing of data files to other users or computers. Without the network, the computer system can only work within certain spaces, with no way to share data or files with others far away.

Description
lapo4ka [179]

Answer:

from datetime import time, datetime, timedelta, date

for _ in iter(list, 0):

   t1 = input("Please enter time one: ")

   t2 = input("Please enter time two: ")

   if t1.isdigit() == True and (int(t1[:2])<=23 and int(t1[2:]) <= 59)\

       and t2.isdigit() == True and (int(t2[:2])<= 23 and int(t2[2:])<=59):

       time_1 = time(hour=int(t1[:2]), minute=int(t1[2:]))

       time_2 = time(hour= int(t2[:2]), minute=int(t2[2:]))

       if time_1 > time_2:

           diff = datetime. combine (date. today( ), time_1) - datetime. combine(date. today ( ), time_2)

       else:

           diff = datetime. combine (date. today( ), time_2) -datetime. combine(date. today ( ), time_1)

       diff_list = str(diff).split(":")

       del diff_list[2]

       diff_t = "". join (diff_list)

       print(diff_t)

       break        

   if t1.isdigit() == False or t2.isdigit() == False:

       print("Military Time Forest Required: Bad input, try again.")

       continue

   elif int(t1[:2])> 23 or int(t2[:2])> 23:

       print("Military Tine Format Required: Hours must be between 00 and 23, try again")

       continue

   elif int(t1[2:])> 59 or int(t2[2:])> 59:

       print("Military Tine Format Required: Minutes must be between me and 59, try again")

       continue

Explanation:

The python Datetime package is used to manipulate date and time, creating immutable Datetime objects from the various python data types like integer and string. The block of code above is a conditional for-loop statement that gets two user time value inputs and prints out the difference as a string in Military forest time format.
