Why is it important for an engineer who is designing a new home-cooling/heating system to have knowledge about the transfer of heat?
Answer:
so he can know where to put the heating things so he will know which place will trap the most heat. He will also need to know that depending on where he puts the cooling system, where it will make the most use.

How can friction help you/hurt you?
Explanation:
Friction helps to move
and friction hurt if you if the floor is washed by washing powder and floor is wet and you can fell....
Answer:
Explanation:
Advantages/uses/helpful ;
•Being able to walk across a surface without slipping. This is static friction.
•Writing on a piece of paper with a pencil or a pen. This is sliding friction.
•Driving a car across the road surface. This is rolling friction.
Disadvantage/hurts you;
•Static friction must be overcome, by either muscle tension or gravity , in order to move. Once moving, kinetic friction acts to oppose motion, cause wear on joint surfaces, generate thermal energy , and make the body less efficient.
•Friction produces unnecessary heat leading to the wastage of energy.

Scientists have discovered convection currents inside Earth. Explain how these convection currents move and what layer(s) they occur in.
Answer:
It occurs in the mantle. As the core heats up the bottom of the mantle, the particles move faster causing the mantle to lose density. That causes it to rise and the rising starts the Convection Currents.
The convection currents occur in the mantle layer of the earth The stiff tectonic plates of the Earth move in response to convection currents in the planet's fluid, molten core.
What are convection currents?Convection currents are fluid motions brought on by temperature or density variations within a substance. Because the particles within a solid are fixed in place, convection currents are only visible in gases and liquids. A straightforward illustration of convection currents is warm air rising toward a home's ceiling or attic.
Differential heating leads to convection currents. Warm, less dense, lighter material rises while cool, more dense, heavier material sinks. Convection currents are patterns of circulation that are produced by this movement in the Earth's mantle, oceans, and atmosphere.
It takes place in the mantle. The particles travel more quickly toward the bottom of the mantle as the core heats it, causing the mantle to lose density. It rises as a result of that, and the rising causes the Convection Currents to begin.

What uses for nanowhiskers can you imagine? (Short answer please)
Answer:
Suit (keeps you warm in cold water) removes stains on fabric
Explanation:
Chitin nanowhiskers are primarily used to reinforce polymer nanocomposites, but they are also used to prepare scaffolds, hydrogels, and sterile gauze, as sorbent materials in industry, water purification, and so on.
What are nanowhiskers?Nanowhiskers are a type of crystal nanofiber with a diameter less than 100nm and a length-to-diameter ratio greater than 100.
Fullerene nanowhiskers (FNWs) are thin crystalline fibers made up of C60, C70, endohedral, or functionalized fullerene molecules.
The Nanowhiskers repel stains by creating an air cushion around each cotton fiber. When something is spilled on the fabric's surface, the miniature whiskers actually prop up the liquid drops, allowing them to roll off.
Chitin nanowhiskers are principally sometimes used reaffirm nanocomposite, but they are also employed to make scaffolds, hydrogels, and sterile gauze, as well as sorbent materials in industry and water purification.
Thus, these are some of the uses of nano-whiskers.

An object falls through the air, gaining speed as it falls. A student claims that this creates new energy, and so it breaks the law of energy. Which statement describes why the student is incorrect?
Answer:
D
Explanation:
Energy is never created nor destroyed.
If an object falls through the air, gaining speed as it falls. A student claims that this creates new energy, and so it breaks the law of energy, then the statement describing why the student is incorrect is "Energy is converted from other forms not created, therefore the correct answer is option D.
What is mechanical energy?Mechanical energy is the combination of all the energy in motion represented by total kinetic energy and the total stored energy in the system which is represented by total potential energy.
As given in the problem statement If an object falls through the air, gaining speed as it falls. A student claims that this creates new energy, and so it breaks the law of energy.
"The energy is neither created nor destroyed it can only convert from one form to another".
Thus, the correct answer is option D.

Liquid 1 reacts with Liquid 2, producing a solid and a gas. Using this scenario, which supports the law of conservation of mass?
mass of Liquid 1 + mass of solid = mass of Liquid 2 + mass of gas
mass of Liquid 1 – mass of solid = mass of Liquid 2 – mass of gas
mass of Liquid 1 – mass of Liquid 2 = mass of solid + mass of gas
mass of Liquid 1 + mass of Liquid 2 = mass of solid + mass of gas
Answer:
the guy above me is right just so you are douting its d
Explanation:
The mass of Liquid 1 + mass of Liquid 2 = mass of solid + mass of gas supports the law of conservation of mass option (D) is correct.
What is mass?A tangible body's mass is the amount of matter it possesses. It's also a metric of inertia or the resistance to velocity when a net force is exerted.
As we know,
The law of conservation of mass is also known as the principle of mass conservation.
In physics and chemistry state that for any system close to all transfers of matter and energy.
The mass of the system must remain constant over time because the mass of the system cannot change and therefore quantity cannot be added to or subtracted.
Thus, the mass of Liquid 1 + mass of Liquid 2 = mass of solid + mass of gas supports the law of conservation of mass option (D) is correct.

vf= 13m/s + (0.08m/s²) (180s)
Answer:
vf = 27.4 [m/s]
Explanation:
Para poder simplificar tiene que identificar las unidades que tiene en la ecuacion:
0.08 [m/s²] = aceleracion
180 [s] = tiempo
13 [m/s] = velocidad
al multiplicar aceleracion por tiempo podemos obtener velocidad ya que el tiempo se elimina con segundos al cuadrado
[tex][\frac{m}{s^{2} } ]*[s] = [\frac{m}{s} ][/tex]
vf = 13 + (0.08*180)
vf = 13 + 14.4
vf = 27.4 [m/s]
