Answer:
the relationship between the voltage and the resistance is linear,
light bulb. a lot of energy to be in the system in the form of electromagnetic radiation and heat, this loss of energy is the cause of the loss of the linearity of ohm's law.
Explanation:
When you study ohm's law
V = i R
You observe that the relationship between the voltage and the resistance is linear, so the law of compliance, when you used a resistor, the law was fulfilled, the resistor did not heat up significantly.
When you used the bulb, the resistance values is small, so the passing current is high and the filament heats up significantly, to the point of emitting light, so the resistance can linearity. This is because the collisions between the electrons and the atoms is very frequent creating excitations and de-excitations that cause a lot of energy to be in the system in the form of electromagnetic radiation and heat, this loss of energy is the cause of the loss of the linearity of ohm's law.
Answer:
Magnetic flux will be equal to
Explanation:
It is given radius of circular loop r = 0.10 m
Area of circular loop
Magnetic field B = 0.20 T
Angle between plane of loop and magnetic field
Magnetic flux will be equal to
So magnetic flux will be equal to
Answer:
B. ceramics
Explanation:
Ceramics are materials which are inorganic and non-metallic materials made from compounds of metals and non metals. They are usually oxides, carbides and nitrides. They are stronger, harder and more resistant to heat than a wide variety of other types of materials. They found a great use in the industry such as for making glass wares, pottery , valves, spark plugs, pressure sensors, vibration sensors,bricks, cement,insulators, resistors, superconductors, capacitors ,ceramic rotors e.t.c.
Well as a biology student my first instinct is that they both have a thin outer coating. The cell has its cell surface membrane and the gold medal has its thin layer of gold.
