Gr. 8
Think it has something to do with Viscosity, Density, and Pressure but not sure what
Answers
Answer: 1. Material being transported 2. The temperature of the material being transported 3. How long the pipes will be there (lifespan)
Explanation: 1. - The pipe builder should consider the material being transported to choose the correct material of the pipes to use, so they last long and can hold the material.
2. - Similar to 1, the pipe builder should consider the temperature of the material to choose the correct material of the pipes to use, so the pipes don’t break and function properly.
3. - If the pipe builder uses a material that can hold the material, that’s great! If that material will last a short time, it would not work if the pipes were to be used for a long time.
The things you said before about viscosity, density, and pressure are also correct. The correct answers are mainly talking about factors of the material being used in the pipes.

Soil classification is partially determined by the presence of organic material, such as humus. Which would have more humus—a desert or a forest—and why? Check all that apply.
a forest because it has more trees to provide plant litter
a desert because it has soil with a larger particle size
a forest because it has more animals to mix the soil
a forest because the trees prevent rain from reaching the soil
a desert because the dry air decomposes plant litter
Answers
a desert because it has soil with a larger particle size. Hence option B is correct. Hence option B is correct.
What is Dessert ?Dessert is the final course of a meal. The dish includes sweet snacks like sweets and sometimes a beverage like dessert wine or liqueur. There is no tradition of a dessert course to finish a dinner in several regions of the world, such as Greece and West Africa, and in most parts of China.
Desserts include biscuits, cakes, cookies, custards, gelatins, ice creams, pastries, pies, puddings, macaroons, sweet soups, tarts, and fruit salad. Fruit is also typically seen in dessert courses due to its inherent sweetness. Desserts are made in certain cultures by sweetening savoury dishes. In the 18th and 19th centuries, when refined sugar and wheat were widely available and ostentation and artifice were desired, the dessert course achieved its pinnacle in the feasts of the European courts. Numerous creams, tarts, fruits, cakes, pastries, puddings, jellies, and meringues were given on tables decorated with flowers and architectural fancies made of sugar and pastry.
Hence option B is correct.

List an example of matter in each of the three states.
Answers
The example of matter in the three states is brick in solid state, water in liquid state and oxygen gas in gaseous state.
1. Solid: A brick is a solid object that maintains a fixed shape and volume.
2. Liquid: A glass of water is a liquid that conforms to the shape of its container but maintains a definite volume.
3. Gas: Oxygen gas in the atmosphere is a gas that does not have a fixed shape or volume, filling the available space.
The three states of matter are solid, liquid, and gas. Solids have a fixed shape and volume, such as an ice cube. Liquids have a definite volume but take the shape of their container, like water. Gases have neither a fixed shape nor volume and fill the entire space available to them, such as the air we breathe.
In summary, the states of matter describe the physical properties of substances based on the arrangement and movement of their particles, with solids having a fixed shape, liquids taking the shape of their container, and gases being free-flowing and filling all available space.

Solid: An object that keeps a constant shape and volume is a brick.
Thus, Liquid: A glass of water is a liquid that keeps a consistent volume while taking on the shape of its container. Gas: Oxygen gas fills the available space in the atmosphere and does not have a defined shape or volume.
Gas, liquid, and solid matter can exist in any combination. Solids, like an ice cube, have a set shape and volume.
Like water, liquids have a set capacity but adopt the shape of their container. Gases, like the air we breathe, have neither a set shape nor volume and fill all available space.

How does the sport curling relate to Newton’s Second Law of Motion?
Answers
Curling is a sport in which players slide stones across a distance of ice toward a target area. The purpose is to accumulate the loftiest score for a game by making monuments rest closest to the center of the target at the end of each side. There are two brigades. Each platoon is trying to keep the other platoon's monuments down from the target by knocking their monuments out of the way.
Newton's Second Law " The acceleration of an object is directly commensurable to the net force acting on it and is equally commensurable to its mass. The direction of the acceleration is in the same direction as the net force acting on an object." This relates to the formula F = ma. The mass of the determinedness monuments in curling is 38 to 44 pounds or 17.3 to 20 kg. The thing of the sweepers is to control the acceleration of the gravestone by reducing disunion on the ice, which affects the force with which the gravestone is suitable to impact the other monuments.

https://brainly.com/question/25545050
Second law-
Newtons second law occurs during curling when the delivery man, such as Glenn Howard, applies force to the stone pushing down the lane to the target while friction pulls it back the other way to a slow stop. The mass of the stone is 40lbs and the net force of everything on item will give you its slowly decreasing acceleration. Otherwise known as, F=mA.
Third law-
This law can be exerted in the sport of curling when the force behind a stone being delivered is transferred into another stone that is at rest, where the energy and force of one moving object is transferred to another. This almost completely stops the original stone, and gives some speed to the stone(s) it collides with.

(ANSWER ALL QUESTIONS PLEASE!)
Answers
Answer:
1 question- Three different things happen when light hits a surface, it can be reflected (bounce off), absorbed or transmitted (pass through). Glass reflects some light but most of the light is transmitted straight through. That's why we can see objects on the other side of a closed window. We say that glass is transparent.
2 question- All materials have what is known as an index of refraction, which is linked to how fast light can travel through the material. As light passes through air and into another clear material (such as glass), it changes speed, and light is both reflected and refracted by the glass
3 question- The energy of a wave is directly proportional to its frequency, but inversely proportional to its wavelength. In other words, the greater the energy, the larger the frequency and the shorter (smaller) the wavelength
4 question- The most dangerous frequencies of electromagnetic energy are X-rays, gamma rays, ultraviolet light and microwaves. X-rays, gamma rays and UV light can damage living tissues, and microwaves can cook them
5 question- Heat can travel from one place to another in three ways: Conduction, Convection and Radiation. Both conduction and convection require matter to transfer heat. Conduction is the transfer of heat between substances that are in direct contact with each other. Thermal energy is transferred from hot places to cold places by convection. Radiation is a method of heat transfer that does not rely upon any contact between the heat source and the heated object as is the case with conduction and convection. Heat can be transmitted through empty space by thermal radiation often called infrared radiation.

The group which was designed to study Saturn is C. Voyager 1, Huygens, and Cassini. It was a collaborative mission involving NASA, ASI, and ESA.
The trio of Voyager 1, Huygens, and Cassini embarked on groundbreaking missions, collectively enhancing our understanding of Saturn and its diverse moons. Launched by NASA in 1977, Voyager 1 ventured into the outer solar system, conducting close flybys of Jupiter and Saturn, capturing detailed imagery and valuable scientific data.
Huygens, a constituent of the collaborative Cassini-Huygens mission involving NASA, ESA, and ASI, made a historic touchdown on Saturn's moon Titan in 2005. It meticulously examined Titan's atmosphere and surface, yielding unprecedented insights.
Meanwhile, the Cassini spacecraft, another integral part of the Cassini-Huygens mission, meticulously orbited Saturn for more than 13 years. Cassini extensively studied Saturn's rings, atmosphere, and numerous moons, unraveling captivating discoveries such as new moons and tempestuous storms.
The Cassini mission culminated with a planned atmospheric entry into Saturn. These missions collectively revolutionized our knowledge of Saturn, its enigmatic rings, and its captivating moons.
