A brick has a weight of 23N. The brick is flat and smooth on the side in contact with the floor having measurements ( height= 5cm, length =20cm, width=10cm).
A)Calculate the area of the brick in contact with the floor. Give your answer in cm2.
B)Calculate the pressure of the brick on the floor.
Answer:
A)Area = 200[tex]cm^{2}[/tex]
B) Pressure = 0.115 N/[tex]cm^{2}[/tex]
Explanation:
Assuming that the brick is flat on the floor with its largest face towards the floor and not on its side, then we can calculate the area of that face by multiplying the length by the width like so...
Area = length * width
Area = 20cm * 10cm
Area = 200[tex]cm^{2}[/tex]
The formula for calculating pressure is force divided by area. Therefore, since we just finished calculating the area and the force is given to us in the question (23N) we can simply plug in these values and solve for the pressure.
Pressure = Force / Area
Pressure = 23N / 200[tex]cm^{2}[/tex]
Pressure = 0.115 N/[tex]cm^{2}[/tex]
Why is the energy pyramid not a smooth geometric shape like a triangle but, rather, looks like narrow blocks stacked on top of wider blocks?
Answer:
See explanation
Explanation:
As energy is transferred from one trophic level to another, energy decreases at each level, and only 10% of the energy from the previous level is transferred to the next higher level.
This is because, organisms at each level use the energy obtained from food materials for their own metabolic activities.
Hence, the energy pyramid is not a smooth geometric shape like a triangle but, rather, looks like narrow blocks stacked on top of wider blocks. Each higher level is smaller in size than the previous level because lesser energy is transferred to the next higher level.

Individuals connect to the Internet through an __ (1) __ allowing them access to the system. The rules on the Internet for how messages are addressed and passed on are called __ (2) __ .
Each device on the internet has a unique numeric address called an __ (3) __ , which can be looked up automatically using a __ (4) __ , which is like a giant address book.
Each message is broken up into small pieces called __ (5) __ that are sent individually which makes the Internet more reliable. Since packets often arrive out of order, they include information about the order in which they should be arranged as well as who the sender and receiver are.
Packets are guided through the internet by __ (6) __ . Having multiple paths or __ (7) __ makes the Internet more reliable and allows it to keep growing as more people and devices are connected to the system.
Answer:
1. Internet service provider (ISP)
2. Protocols.
3. IP address.
4. Domain name server (DNS)
5. Packets.
6. Routers.
7. Redundancy.
Explanation:
Individuals connect to the Internet through an internet service provider (ISP) allowing them access to the system. The rules on the Internet for how messages are addressed and passed on are called protocols. A protocol can be defined as a standard set of rules established by the regulatory agencies to determine how data are transmitted from one network device to another.
Each device on the internet has a unique numeric address called an IP address, which can be looked up automatically using a domain name server (DNS), which is like a giant address book.
Each message is broken up into small pieces called packets that are sent individually which makes the Internet more reliable. Since packets often arrive out of order, they include information about the order in which they should be arranged as well as who the sender and receiver are.
Packets are guided through the internet by routers. Having multiple paths or redundancy makes the Internet more reliable and allows it to keep growing as more people and devices are connected to the system.

Consider the following code:
grid = []
grid.append (["frog", "cat", "hedgehog"])
grid.append (["fish", "emu", "rooster"])
What is output by:
print (grid[0][0])
also these two
print (grid[1][2])
print (grid[0][1])
Answer:
print(grid[0][0]) = frog
print(grid[1][2]) = rooster
print(grid[0][1]) = cat
Final output:
frog
rooster
cat
Explanation:
grid[0][0] is the first item in grid[0], which is "frog".
grid[1][2] is the last/third item in grid[1], which is "rooster".
grid[0][1] is the second item in grid[0], which is "cat".
Simply add 1 when dealing with list indexes, that's all you need to do!
In Python, the list is a mutable, or changeable, ordered series containing elements. so, the output of the given python program code is "frog, rooster, and cat".
Program explanation:Defining an empty list that is a "grid".Inside the list, the append method is declared which adds string value to the list.In the next line, three print method is used that calls the list values.In the first print method, it calls the first index value "0,0" which is "frog".In the second print method, it calls the second index value "1,2" which is "rooster".In the third print method, it calls the first index value "0,1" which is "cat".Output:

The pH scale measures the concentration of hydrogen lons in acidic and alkaline solutions?
Answer:
True.
Explanation:
The pH scale measures the concentration of hydrogen ions in acidic and alkaline solutions.
In chemistry, it literally means power of hydrogen ions and it is a measure of the molar concentration of hydrogen ions in a particular solution, thus specifying the acidity, neutrality or basicity of chemical solutions.
Mathematically, the pH of a solution is given by;
[tex] pH = -log_{10}(H^{+}) [/tex]
Hence, a solution with a pH of 7 is neutral. Also, a solution with a pH below 7 is acidic but basic (alkaline) if it's pH is above 7.
