Answer:
Fs = 32N
Fh = 21 N
Explanation:
Statics
Let Fs be the force of the shoulder, assumed upward
Let Fh be the force of the hand, assumed downward
Sum moments about the hand to zero
1.1(9.8)[67] - Fs[22.5] = 0
Fs = 32N
Sum vertical forces to zero
32 - Fh - 1.1(9.8) = 0
Fh = 21 N
Or we could sum moments about the shoulder point
1.1(9.8)[67 - 22.5] - Fh[22.5] = 0
Fh = 21 N
I can answer number 2 for you only. I don’t know if it’s correct or not this is what I THINK it is:
2. Burning fossil fuels creates greenhouse gases, which changes the climate.
Ps. Climate is long term weather. Aka weather over a long period of time.
Answer:
A bar chart is typically used for the comparison of informations obtained from a data collection by representing each value (information) with rectangular bars respectively.
Explanation:
A bar chart also known as a bar graph can be defined as the graphical representation of data (informations) by using vertical columns or rectangular bars. When a data set is observed, a bar chart can be used to graphically represent or record the total or overall amount of information contained therein. Generally, bar charts are used for the comparison of informations obtained from a data collection by representing each value (information) with rectangular bars respectively.
The bar graph has a x-axis and a y-axis used to represent the various categories of data collected.
In this scenario, the x-axis is used to denote the points earned by the teams while the y-axis is used to denote the seasons as seen in the image attached.
<em>Hence, point scores by team (Team A, B and C) per seasons (2002, 2003, 2004 and 2005) can best be compared through the use of a bar chart (graph).</em>
Answer:
1. Both are respiratory organs found in vertebrates.
2. Both enable the inhalation of oxygen and exhalation of carbon dioxide in the bodies of their host.
3. Respiratory membranes present in both make the exchange of gases easier.
4. Blood vessels found around them enable the breathing process.
Explanation:
Gills are respiratory organs which can be found in animals that live in water. These include fishes, amphibians like frogs, anthropods like insects, and annelids like worms. Gills are surrounded by respiratory membranes known as gill lamellae which have a large surface area that makes breathing easier. Blood vessels also are found around gills.
The lung is also a respiratory organ found in humans. It runs from a windpipe known as the trachea and branches into bronchi which contain the bronchioles. Alveoli ducts contain alveoli sacs and then alveoli which are membranes that enable the breathing process.
Both are similar because they are respiratory organs found in animals with backbones. They are surrounded by blood vessels and membranes that make the breathing process easier.
