Answer:
Fluid power systems perform work by a pressurized fluid bearing directly on a piston in a cylinder or in a fluid motor. A fluid cylinder produces a force resulting in linear motion, whereas a fluid motor produces torque resulting in rotary motion. Within a fluid power system, cylinders and motors (also called actuators) do the desired work. Control components such as valves regulate the system.

The modern day three little pigs will need to choose from the following materials to build their energy efficient home: Vibranium, Beskar, and Gundarium
order for the three little pigs to be successful in building an insulated home that loses as little heat as possible, they will need to choose the materal with ta
highest specific heat, Cp-
Vibranium
Choosing the material with the highest specific heat capacity is ideal and true.
What is Specific heat capacity?This is defined as the quantity of heat needed to raise the temperature per unit mass.
Insulators have a higher specific heat capacity as it takes more time for them to absorb heat thereby making it ideal in building an insulated home.

How many moles in 16 grams of oxygen?
Answer:
Half mole or 0.5 moles
__________________________________________________________
SolveOxygen has a molar molar mass of 32 g.
This means that O2 will have half that amount of grams, half-mole-substance.
6.022*10^23 molecules are present in one mole of any substance, so half it for O2.
6.022 × 10²³ [tex]-- >[/tex] 3.011 × 10²³
And simplified, that would make your answer 0.5 moles.

How does tension affect the speed of a wave in a rope
a
Scientists have observed that the average surface temperature of the Earth has been increasing. This increase has
affected the oceans. Glaciers and ice sheets melt, and water from this melting process becomes part of the oceans.
The increasing temperature of the Earth's surface also warms ocean waters. As a result, the volume of the oceans
expands. These two events affect sea level.
What would happen to sea level if the average surface temperature trend that was observed since the 1960s
continues?
A) Sea level will rise, then will suddenly fall.
B) Sea level will remain the same.
C) Sea level will continue to fall.
D) Sea level will continue to rise.

A mixture of heptane (bp 98oC) and 1-propanol (bp 97oC) is not fully resolved using SE-30 as the stationary phase, but is easily separated using a column of DEGS. Explain with your own words.
A mixture of heptane and 1-propanol easily dissolved using DEGS because diethylene glycol sussinate (C8H14O6) 1 propanol easily dilutes and retain surface.
What is mixture?Generally, a mixture speaks to the joining of two different substance in other to achieve a different substance or something combining or becoming matched.
In conclusion, SE-30 is neutral in nature, DEGs is a stationary phase containing a non-volatile liquid phase. It also includes polar group OH types,
Hence, using Hydrogen bonding it can easily bind 1-propanol.

To calculate the atoms of an element in a given molecule, we need to multiply stoichiometry by the number that is written on the foot of that element. The correct option is option A.
What is Balanced equation?Balanced equation is the one in which the total number of atoms of a species on reactant side is equal to the total number of atoms on product side. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, displacement reaction.

A liquid has an empirical formula CCl2, and a boiling point of 1 21 oC. When vapourised, the gaseous compound has a density of 4.93 g/L at 785torr and 1 50oC. What is the molar mass of the compound and what is its molecular weight?
Based on the data given, the molar mass of the gas is 165.5 g/mol while the molecular weight of the gas is 165.5 amu
How can molar mass of a gas be obtained from density, temperature and pressure?The molar mass of a gas can be obtained from density, temperature and pressure using the formula below:
molar mass = density × molar gas constant × temperature/pressureMolar gas constant, R = R = 0.082 L.atm/mol/K.
Temperature = 150 °C = 423 K
Pressure = 785 torr = 1.033 atm
density = 4.93 g/L
molar mass of gas = 4.93 × 0.082 × 423/1.033
molar mass of gas = 165.5 g/mol
Then, molecular weight of the gas = 165.5 amu
Therefore, the molar mass of the gas is 165.5 g/mol while the molecular weight of the gas is 165.5 amu

Which statement best describes how potassium bonds with bromine?
Potassium will donate an electron to bromine.
Bromine will donate an electron to potassium.
Bromine will donate seven electrons to potassium.
Potassium will share seven electrons with bromine.
Answer:
Potassium will donate an electron to bromine.
Explanation:
When potassium and bromine come together, the more electronegative bromine will snatch that solitary valence electron from the potassium atom. This will lead to the formation of the potassium cation, K+ , and the bromide anion, Br− .
