Explanation:
Benjamin Franklin invented the lightning rod as a way to prevent lightning from causing damage to property or people. Use this same idea to construct a device that can protect a person from static charge buildup in their body as they run on a treadmill. Consider that the person wears rubber-soled shoes that rub on the treadmill's running surface, which generates static charges that build up in their body. When the person finishes her workout, she can receive an unpleasant shock when she steps off the treadmill and touches an object that suddenly discharges all of that charge. How can you apply Ben Franklin's idea of a lightning rod to solve this problem? Create a sketch showing how your shock protection system works. Your sketch should be labeled and clearly indicate how the excess static charge in a human body is discharged by the system you design. 12 f(x) (1000) 1 G
Answer:
By 1750, in addition to wanting to prove that lightning was electricity, Franklin began to think about protecting people, buildings, and other structures from lightning. This grew into his idea for the lightning rod. Franklin described an iron rod about 8 or 10 feet long that was sharpened to a point at the end.

Suppose you make your living fishing for lobster. You and everyone else are free to set out as many traps as you like. As more and more traps are set up, however, fewer and fewer lobsters are caught. Soon, lobster catches are too small to support your families. A meeting is coming up where you and your fellow lobster fishers will present possible solutions to this problem. What will you propose to combat this tragedy of the commons and restore the fishery?
Explanation and Answer:
This is an opinion based question and there could be many different responses these are just examples of solution to restore the fishery:
-limiting the season during which lobsters can be caught this allows the population to reproduce itself gradually but maintaining it in control
-limiting the amount of lobster that can be caught therefore again letting the population increase

Which of the following statements about salinity is true?
Question 1 options:
Ocean water near rivers has a lower salinity.
Ocean water near areas with low evaporation has higher salinity.
Ocean water in regions with high levels of precipitation has higher salinity.
Ocean water in areas with high humidity has a higher salinity.
Answer:
the answer is A
Explanation:
I took the test
Salinity of water is the total concentration of the salts present in unit volume of water. Ocean water in regions with high levels of precipitation has higher salinity. Hence option c is correct.
What is salinity ?The salinity of sea water is expressed as a salt (in g) to liter of water ratio. Each liter of sea water contains around 35 grams of dissolved salts. It is spelled 35. The usual range of ocean salinity is 33-37 g/L.
There is a lot of rain in some places of the ocean. Freshwater poured to the surface dilutes the seawater, reduces salinity, and hence makes the seawater less dense. Near land, where rivers provide freshwater, seawater may be less saline.
The seawater near Antarctica has a low salinity of little about 34 ppt, and it is as low as 30 ppt in some spots around the Arctic. Regions where, the precipitation is higher have higher salinity in oceans.

How do the two desalination processes differ from the atmospheric water generator in terms of where the processes can be used?
Answer:
Water Desalination Processes. Water desalination processes separate dissolved salts and other minerals from water. Feedwater sources may include brackish, seawater, wells, surface (rivers and streams), wastewater, and industrial feed and process waters. Membrane separation requires driving forces including pressure (applied and vapor)
Explanation:
Salinized water cannot be consumed by humans, but it can be converted into freshwater, which has a variety of purposes. Desalination is the procedure, and it is being employed increasingly frequently all over the world to supply people with the freshwater they require.
What is desalination process?Desalination is the procedure used to remove the dissolved mineral salts from water. Currently, one of the most popular methods for obtaining fresh water for use in agriculture or human consumption when applied to seawater.
When seawater evaporation occurs, salt is left behind, and clouds are formed, which eventually result in rain. Da Vinci realised that it was easy to obtain using a still. Aristotle had observed that seawater would evaporate and condense into fresh water.
Seawater desalination was mostly utilised on ships and submarines over the next centuries to supply the crew with fresh water during lengthy voyages. Nevertheless, this method was not widely accessible until the industrial revolution and, more specifically, until the creation of desalination facilities.

While heating up a 25 gram sample of concrete (specific heat = 0.210-cal/g°C), your initial tempărature is room temperature (25°C), you found that the substance gained 305 calories. What was the final temperature of your sample?
**Round your answer to the nearest 0.1**
I got 83.1 but I just want to check it
Answer:
Final temperature = 83.1 °C
Explanation:
Given data:
Mass of concrete = 25 g
Specific heat capacity = 0.210 cal/g. °C
Initial temperature = 25°C
Calories gain = 305 cal
Final temperature = ?
Solution:
Q = m. c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = T2 - T1
305 cal = 25 g ×0.210 cal/g.°C × T2 - 25°C
305 cal = 5.25cal/°C × T2 - 25°C
305 cal / 5.25cal/°C = T2 - 25°C
58.1 °C = T2 - 25°C
T2 = 58.1 °C + 25°C
T2 = 83.1 °C

Hydrogen atoms fuse together to form helium atoms. This releases a huge amount of energy in the form of _______ and ______. (called Nuclear fusion)
Answer:
Hydrogen atoms fuse together to form helium atoms. This releases a huge amount of energy in the form of Kinetic energy of the alpha particle and Electromagnetic radiation.
Explanation:
Nuclear Fusion is the Nuclear process in which the energy is produced when two lighter elements are collided together which are having some kinetic energy in them after that the two lighter nuclei will fuse together into a single heavier nuclei. This is opposite to what happens in Fission process in which the breaking up of atomic specie happens.
Both Nuclear Fission and Nuclear fission occurs with the release of massive amount of energy.
There are conditions for nuclear fusion to happens like, it requires 100 million's kelvin of temperature, also fusion will occur when the pressure is very high because increased pressure will result into squeezing of the atomic specie and hence they will fuse.
When the Hydrogen atom fuse together to form helium atoms. This release a huge amount of energy in the form of Kinetic energy of the alpha particle and Electromagnetic radiation.
