Answer:
1) 6(1/2)
2) 8(4/5)
Explanation:
1) 7 - 1/2 = 7/1 - 1/2 = 14/2 - 1/2 = 13/2 = 6(1/2)
2) 11(2/5) - 2(3/5) = 57/5 - 13/5 = 44/5 = 8(4/5)
Answer:
A solution mixture is a homogenous mixture of two or more substances where one substance has dissolved the other.
A Colloid mixture is a homogenous mixture where the particles are small enough that they stay suspended. and are evenly distributed throughout another substance.
A Suspension mixture is a type of heterogeneous mixture where solid particles do not dissolve in a liquid solution
An example of a solution mixture are salt water, rubbing alcohol, and sugar dissolved in water. When you look closely, upon mixing salt with water, you can't see the salt particles anymore, making this a homogeneous mixture
An example of a colloid mixture include whipped cream, mayonnaise, milk, butter, gelatin, jelly, muddy water, plaster, colored glass, and paper. Every colloid consists of two parts: colloidal particles and the dispersing medium
An example of a suspension mixture is water and sand When mixed up, the sand will disperse throughout the water. If left alone, the sand will settle to the bottom.
Answer:
Yes, this is possible.
Explanation:
It is possible that a cup of tea and teapot filled with tea has the same thermal energy. This often occurs in the real world, when two different thermal energy bodies are placed next to each other.
When two bodies are placed next to each other and these two bodies have different temperatures, there is a transfer of thermal energy between them, which allows them to present the same thermal energy.
With that we can conclude that the teapot received thermal energy from the stove and passed that energy to the tea that was inside it, in this way, tea and teapot had equal thermal energy. This tea, with high thermal energy, was placed in a cup with low thermal energy. The tea promoted a transfer of heat between him and the cup, allowing them to equalize their temperatures and consequently the thermal energy.
In this way, the cup has the same temperature as the tea, which has the same temperature as the teapot.
Write a few sentences summarizing what you already know about these topics.
The choice of renewable energy sources to be developed depends on the geographical and environmental characteristics of an area. Wind and tidal energy could be suitable for a coastal region, solar energy might be ideal for a sunny, arid region, and biomass energy could work well in forested areas. Setup and costs can vary depending on the specific circumstances.
The optimal types of renewable energy sources to be developed in a given area typically depend on the environmental and geographic factors of that area. In a coastal region, for example, harnessing wind energy and tidal energy could be very appropriate and effective. Wind turbines can be set up onshore or offshore to generate electricity from the consistent and powerful coastal winds, while tidal power plants can harness the energy of incoming and outgoing tides.
On the other hand, in a sunny, arid region like a desert, solar energy would likely be the most feasible and abundant source of renewable energy. Solar panels can be efficiently installed in these areas to convert sunlight directly into electricity.
Finally, in an area with abundant biomass resources (such as forested areas), biomass energy can be a good choice. This form of energy uses organic materials (like wood, crop waste, or even algae) to create heat, fuel, or electricity.
The ease of setup and costs associated with each type of renewable energy source can vary significantly depending on the specific factors of each location, as well as the type and scale of the energy project.

Answer:
There is a lot but here are some!
Wind: Wind power is growing rapidly, and is becoming a well-recognized renewable energy resource. Using wind power to turn turbines that generate electricity can provide a cheap source of energy. Building and maintaining equipment could provide thousands of jobs and cost-efficient and clean electricity. Wind farms, however, are not particularly popular. They can impact local environment and wildlife, and even provide noise pollution. Additionally, many people feel that the equipment used obstructs scenic views.
Solar: This is perhaps the most recognized renewable energy source. Energy from the sun is captured using cells made from special materials (silicon is quite popular right now) and then converted into electricity. The biggest factor in solar cell production is cost. However, with technological advancements solar is becoming more cost efficient, and high efficiency solar cells are being developed. This is important, since high efficiency cells are hard to come by. New materials are providing solar cells that are easier to transport and install. Flexible solar cells can be used for residential use, and building solar arrays is becoming popular. One of the main factors in efficiency is the fact that solar panels only generate electricity during daylight hours, and can be hampered by cloudy conditions or pollution. Some sort of storage is needed in order to make full use of solar power.
Water: We have been studying water-based renewable energy for quite some time. Hydroelectricity has been a source of energy for years. However, even though the energy production process does not put off pollution, there are other environmental concerns associated with the damming of rivers and ecological impacts stemming from this practice. But hydroelectric power remains one of the more cost-efficient means of generating renewable energy.
Geothermal: Geothermal energy is extracted from the natural processes of the earth. A great deal of heat is created below Earth's surface, and efforts are being made to extract and use this power. While the ancient Romans knew about and used geothermal heating, now Earth's processes are being used to generate electricity -- going beyond space heating. Geothermal power does not put off greenhouse gases (although some harmful gases from deep in the earth would be released -- and need to be contained), and it is reliable. However, it can only be used in areas where there is tectonic activity.
Nuclear: Perhaps the most controversial form of renewable energy is nuclear energy. Electricity is produced from the energy released by nuclear reactions. While fission (splitting) is the main source used today, interest continues in developing cold fusion. Currently, though, power plants generating power using nuclear fission are among the safest plants. They also generate power without emitting pollution. In Europe, France benefits greatly as its nuclear energy produces the cheapest electricity (according to 60 Minutes).
