The correct option is C. 
A system is defined as a collection of components or elements which are dependent on one another and are working together to form a complete unit. The defining feature of a system is interaction; this is because the components of the system are interacting together in order to perform their expected functions.

Answer:

38.8 m/s

Explanation:

Force F(x) = 6 - 2x + 6x²

work

W=\displaystyle\int_{0}^{13.9}F(x)dx=\displaystyle\int_{0}^{13.9}(6-2x+6x^2)dx

=6x-x^2+2x^3|_{0}^{13.9}\\=5261 J

W = mv²/2=7v²/2 = 3.5v² = 5261

v = 38.8 m/s

The boiling point of ethanol is 78 ��
34kurt
  <span>The conversion for Kelvin from Celsius is simple since the units change at same rate (degree for degree) but haven't different zero reference. The Kelvin scale represents absolute zero. The celcius scale moves degree per degree with kelvin scale but has a zero based on freezing point of water. The conversion is 273 + (temperature in celcius) = temperature on kelvin scale. Note 273 is a rounded number to nearest whole number. The actual figure is a number with decimal. 273.15 can also be used if you want more significant figures. 

so 273 + 78C = 351 K </span>

Digestive system: consists of the gastrointestinal tract plus the accessory organs of digestion. Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body.

Endocrine system: a chemical messenger system comprising feedback loops of the hormones released by internal glands of an organism directly into the circulatory system, regulating distant target organs.

Eukaryotes: organisms whose cells have a nucleus enclosed within a nuclear envelope.

Excretory system: an organism's body that performs the function of excretion, the bodily process of discharging wastes.

Golgi Apparatus/complex: an organelle found in most eukaryotic cells. Part of the endomembrane system in the cytoplasm, it packages proteins into membrane-bound vesicles inside the cell before the vesicles are sent to their destination.

Lysosome: a membrane-bound cell organelle that contains digestive enzymes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria.

Mitochondria: a membrane-bound cell organelles that generate most of the chemical energy needed to power the cell's biochemical reactions.

Muscular system: an organ system consisting of skeletal, smooth and cardiac muscles. It permits movement of the body, maintains posture and circulates blood throughout the body

Nervous system: the network of nerve cells and fibers which transmits nerve impulses between parts of the body.

Nucleus: a membrane-bound organelle that contains DNA of eukaryotic organisms. As such, it serves to maintain the integrity of the cell by facilitating transcription and replication processes.

Organ: a group of tissues in a living organism that have been adapted to perform a specific function.

Organism: an individual animal, plant, or single-celled life form.

Organ system: a group of organs that work together as a biological system to perform one or more functions

Prokaryotes: a microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles.

Ribosome: a minute particle consisting of RNA and associated proteins found in large numbers in the cytoplasm of living cells. They bind messenger RNA and transfer RNA to synthesize polypeptides and proteins.

Respiratory system: a biological system consisting of specific organs and structures used for gas exchange in animals and plants.

Rough endoplasmic reticulum: an organelle found in eukaryotic cells. Its main function is to produce proteins. It is made up of cisternae, tubules and vesicles.

Skeletal system: The human skeleton is the internal framework of the human body.

Smooth ER: is a membranous organelle found in most eukaryotic cells

Tissue: a group of cells, in close proximity, organized to perform one or more specific functions.

Vacuole: a membrane-bound organelle.

Calculate the heat flux (in W/m2) through a sheet of a metal 11-mm thick if the temperatures at the two faces are 350 and 110 ˚C
Masja [62]

q = 1156363.6W/m².

To calculate the heat flux per unit area (W/m²) of a sheet made of metal:

q = -k(ΔT/Δx)

q = -k[(T₂ - T₁)/Δx]

Where, k is the thermal conductivity of the metal, ΔT is the temperature difference and Δx is the thick.

With Δx = 11 mm = 11x10⁻³m, T₂ = 350°C and T₁ = 110°C, and k = 53.0 W/m-K:

q = -53.0W/m-K[(110°C - 350°C)/11x10⁻³m

q = 1156363.6W/m²
