Answer:
1. The Sun is the primary source of energy that influences any planet's temperature, including Earth. The amount of energy received from the Sun is called insolation; the ratio reflected is called the albedo.
2.There are three major ways in which global warming will make changes to regional climate: melting or forming ice, changing the hydrological cycle (of evaporation and precipitation) and changing currents in the oceans and air flows in the atmosphere
3.The warming of Earth is primarily due to accumulation of heat-trapping greenhouse gases, and more than 90 percent of this trapped heat is absorbed by the oceans. As this heat is absorbed, ocean temperatures rise and water expands. This thermal expansion contributes to an increase in global sea level.
4.The main sources of greenhouse gases due to human activity are: burning fossil fuels leading to higher carbon dioxide concentrations. farming and forestry — including land use change via agriculture and livestock. cement manufacture.
5. - Reduce, Reuse, Recycle
- Use Less Heat and Air Conditioning
-Use Less Hot Water

Answer:
Option b is the correct answer for the above question.
Explanation:
- The mystery function is a recursive function that calls for the two times when the user passes 38 on the argument.
- The first value is 38 and the second value is 2 for which that function is called.
- When the value 38 is passed, then again 2 is passed because of the "mystery (n % 3);" statement.
- This statement holds by the if condition which gives the true when the argument value is greater than 2.
- Hence for the 2 value the if condition will not true and the function is not called again.
- Then the 38/3 and 2/3 are printed whose value is 12 0, but it will print 0 12 because of the recursive function.
- Hence option b is the correct answer while the other is not because other options does not states the output of this program.
Answer:
Explanation:
Some file formats are fiddly and difficult to open which also makes preservation harder.
Answer:
The switch sends broadcast traffic to all ports like a hub to get the number of ports used and build its MAC address table.
Explanation:
A network switch is a device used in a LAN to connect all available workstations. Unlike a network hub, it is able to send frames from a host or workstation to another using its MAC address table.
An example of a switch is the Cisco 2950 switch. When it is first turned on, it acts as a hub, broadcasting traffic to all its ports. This process is used to create a MAC address table to get the IP address of workstations and the ports they relate to, enabling it to send unicast traffic to a specific port.
