Lyndon is investigating whether putting plastic on her windows will help seal out cold winter drafts. She covers a window on the south side of her house with plastic and measures the inside temperature near the window. She also measures the inside temperature near a window without plastic on the north side of her house. The windows are the same size and design. Why is this not an ideal controlled investigation?
A.
The windows should be different sizes to introduce variation.
B.
The drafts at each window may be different because the windows aren’t near each other.
C.
Temperature isn’t a good indicator of cold winter drafts.
D.
Outside temperature is a better indicator of cold winter drafts than inside temperature.
E.
The type of plastic used in the investigation isn’t mentioned.
Match each context to the type of the law that is most suitable for it.
Boyle’s Law
Charles’ Law
Pascal’s Law
(Match them to the context it goes to)
At constant temperature, the volume of a confined gas is inversely proportional to the pressure to which it is subjected.
A change in pressure at an point in an enclosed fluid at rest is transmitted un diminished to all points in the fluid.
At constant pressure, the volume of a confined gas is directly proportional to the absolute temperature.
At constant temperature, the volume of a confined gas is inversely proportional to the pressure to which it is subjected.
Charles’ LawAt constant pressure, the volume of a confined gas is directly proportional to the absolute temperature.
Pascal’s LawA change in pressure at an point in an enclosed fluid at rest is transmitted undiminished to all points in the fluid.
Further explanationCharles’ LawWhen the gas pressure is kept constant, the gas volume is proportional to the temperature
[tex]\tt \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}[/tex]
Boyle’s LawAt a constant temperature, the gas volume is inversely proportional to the pressure applied
[tex]\tt P_1.V_1=P_2.V_2[/tex]
Pascal’s LawThe pressure exerted by the liquid in a closed space is continued in all directions equally
[tex]\tt P_1=P_2\\\\\dfrac{F_1}{A_1}=\dfrac{F_2}{A_2}[/tex]
A bicycle has tires that are 26 inches in diameter. The while in motion, the tires rotate through 125 complete revolutions. How fast has the bicycle traveled? Give the answer in feet
Answer:
850.8480103 feet
Explanation:
First you take the diameter and find the circumference, which is (2)(pi)(r) plug in your r which is 26/2= 13 so 2(13)(pi) and multiply taht by 125 after that take your answer and divide by 12which is 850.8480103

Reducing waste in a shop doesn't help eliminate safety hazards for
employees.
A True
B. False
Pleasseeee help
Answer:
False
Explanation:
Waste in the shop such as garbage, can cause air pollution, which causes various respiratory diseases and other adverse health effects on employees, as contaminants are inhaled and absorbed from lungs into other parts of the body.
These toxic substances in air contaminated by waste that are inhaled by employees include carbon dioxide, nitrous oxide and methane.
Thus, reducing waste which constitutes toxic substances helps to eliminate safety hazards for employees.

How should you set up your notes when using the Cornell method?
0 with pictures and maps
0 with levels and sublevels
0 with right and left sides
0 with tables and charts
Answer:
With right and left side charts
Explanation:
I was doing research on this exact question, so here is what I have been looking at;
The Cornell method uses a two-column approach. The left column takes up no more than a third of the page and is often referred to as the “cue” or “recall” column. The right column (about two-thirds of the page) is used for taking notes using any of the methods described above or a combination of them. After class or completing the reading, review your notes and write the key ideas and concepts or questions in the left column. You may also include a summary box at the bottom of the page, in which to write a summary of the class or reading in your own words.
Answer:
with right and left sides
