One example of inherent resistance is antibiotic resistance in bacteria. Some bacteria naturally possess genes that allow them to survive exposure to certain antibiotics, reducing the effectiveness of those drugs in treating infections. This inherent resistance can make it challenging to treat bacterial infections and necessitates the development of new antibiotics.
A good example of air resistance is when a skydiver jumps out of a plane and feels the force of the air pushing against their body as they fall. This force slows down their descent and creates drag.
No, different materials have different resistance values. Resistance depends on the material's electrical properties, such as its conductivity and resistivity. For example, metals generally have low resistance due to their high conductivity, while insulators have high resistance due to their low conductivity.
The formula is Resistance= Voltage/ Amps(current) In your example: R=50/2.5, so the answer is 20 ohms.
Air resistance is an example of a type of frictional force acting against an object's motion as it moves through the air. It occurs when the object comes into contact with air molecules, causing a deceleration in its movement.
This is John Connor, you are the Resistance
Wind resistance is a specific example of air resistance. Wind resistance would be a resistance to motion cause by a wind, for example when you try walking forward on a very windy day it is hard, that force preventing you from walking is wind resistance.

Pretending to be sick to avoid work is an example of passive resistance used by slaves.
A nonlinear resistance is a resistance which is different for different voltages ie current is not proportional to voltage. An example of this is the filament of an incandescent lamp.

Durg resistance
An example of fluid friction is the air resistance felt by an airplane.
An example: zircaloy-2 alloy for cladding nuclear fuels elements. Advantages: resistance to corrosion, resistance to stress corrosion cracking, resistance to high pressures and temperatures, not important absoptions of thermal neutrons etc. Another example: gold alloys with copper for jewelry. Advantages: more mechanical resistance, less expensive, less erosion.
Two examples of non linear resistance is a diode and a light bulb.
