Answer:
We choose PTFE
Explanation:
Attached are the modulus density and modulus strength chart.
Due to its young modulus, the density is near 0.5 GPa, as seen in the chart and support water gliding. The PTFE density is between 1 and 10 Mg / cubic meter (see module and chart of density), and the resistance is between 10 and 100 Mpa (see module and chart of strength). Therefore, the finest ploymer will be PTFE that meets the requirements.
Answer:
-50.22kJ
Explanation:
Given:
Initial state Temperature =300k
Pressure 1= 150kPa
Pressure 2 = 800kPa
Volume 1 = 0.2m^3
Work done = Pressure 1 × Volume 1 × (inverse of pressure 1 ÷ pressure 2)
= 150kPa × 0.2m^3 × (inv 150 kPa ÷800 kPa)
= - 50.22kJ
The southernmost rim inlet elevation on the topographical survey is approximately 4.5 feet below the benchmark on the north side of West 55th Street.
What is topographical survey?
A topographical survey, often known as a land survey or topographical land survey, is a type of survey that includes contours. Topographical land surveying determines the exact location and specifications of natural and man-made features on a piece of land. The survey is then turned into a suitable and thorough plan, which incorporates man-made characteristics such as boundaries, neighbouring buildings, sidewalks, and so on. Natural elements such as trees, ponds, and ground contours are also detected by the topographical survey. Having a clear and accurate map of your property might help you avoid costly downstream mistakes caused by unforeseen challenges. It can supply you with the information you need about the land before making any alterations to it.

Answer:
Other formulas equivalent of I=E/R are:
- R = E/I
- E = IR
Where,
R = Resistance
E = Voltage
I = Current
Explanation:
For some conductors of power, the electric flow which will course through them is straightforwardly relative to the voltage concerned them. At the point when a microscopic perspective on Ohm's law is taken, it is found to rely on the way that the float speed of charges through the material is relative to the electric field in the conduit. The proportion of voltage to current is known as the resistance, and if the proportion is constant over a wide scope of voltages, the material is said to be an "ohmic" material. On the off chance that the material can be described by such a resistance, at that point the current can be anticipated from the relationship:
I = E/R
Electric Current = Voltage/Resistance
The voltage changes around any shut circle must total to zero. Regardless of what way you take through an electric circuit, in the event that you come back to your beginning stage you should gauge a similar voltage, compelling the net change around the circle to be zero. Since voltage is electric potential vitality per unit charge, the voltage law can be believed to be an outcome of preservation of vitality. The voltage law has extraordinary handy utility in the investigation of electric circuits. It is utilized related to the present law in many circuit investigation errands.
The electric current in amperes that streams into any intersection in an electric circuit is equivalent to the current which streams out. This can be believed to be only an announcement of preservation of charge. Since you don't lose any charge during the stream procedure around the circuit, the absolute current in any cross-segment of the circuit is the equivalent. Alongside the voltage law, the current law is a useful asset for the investigation of electric circuits.
