It is unlawful for anyone to dispose of fluorescent bulbs as univeral waste.
no
The light bulb gives light be heating the filament. Roughly speaking, it is emitting black body radiation. Plank's Law gives you the formula. See here: http://en.wikipedia.org/wiki/Black_body http://en.wikipedia.org/wiki/Planck's_law
The first law of thermodynamics states that energy cannot be created or destroyed, only transformed. In the case of a light bulb, electrical energy is converted into light and heat energy. The second law of thermodynamics states that some energy is always lost as heat in any energy conversion process, thus not all the energy from the light bulb is converted into light.
You can use Ohm's Law to calculate the current of a light bulb by dividing the voltage across the light bulb by its resistance, which is typically provided on the bulb itself or its packaging. The formula is: Current (I) = Voltage (V) / Resistance (R).

No. CFLs contain Mercury, which is harmful to the environment. Instead, all incandescent bulbs should be replaced with LEDs or newer technology that has no adverse effect on our environment.
Yes, a light bulb obeys Ohm's law since its resistance is constant as long as the voltage across it is constant. Ohm's law states that the current through a conductor is directly proportional to the voltage across it, and inversely proportional to the resistance of the conductor.
To calculate the temperature of a light bulb, you can use the Stefan-Boltzmann law, which relates the temperature of an object to the amount of radiation it emits. You would need to measure the power output of the light bulb and its surface area to calculate the temperature. Keep in mind that the temperature of a light bulb can vary depending on factors like the type of bulb and how it is being used.
The law of conservation of energy states that energy cannot be created or destroyed, only transformed. In the case of a light bulb, electrical energy is converted into light and heat energy. This means that the total energy of the system (electrical energy + light energy + heat energy) remains constant.
No, a higher wattage INCANDESCENT light bulb uses more current than a lower wattage INCANDESCENT light bulb. Some CF and LED bulbs are rated by the amount of light that an incandescent bulb would produce, but they are also rated by the wattage that they use.
The brightness of a light bulb decreases as the distance from the light source increases because the light spreads out over a larger area. This phenomenon is known as the inverse square law, where the intensity of light diminishes proportionally to the square of the distance from the source.
When a light bulb is turned on, electrical energy is transformed into light (radiant) energy and heat energy. This conversion process results in changes in energy form but the total energy remains constant, following the law of conservation of energy.
