How can I increase my lifetime fluorescence? For increasing the fluorescence lifetime of a molecule you have to decrease the Internal Conversion (IC) and Inter System Crossing (ISC). Structural modification is the only way for this. What is the lifetime of phosphorescence? The fluorescence emission took place from a singlet excited states (average lifetime: from […]
What is the hardest concept in physics?

Where is the magnetic field strongest in a solenoid?
Where is the magnetic field strongest in a solenoid? It’s known that at the center of an electromagnet/solenoid the magnetic field B is strongest there. How do you increase the strength of a magnetic solenoid? The strength of the magnetic field around a solenoid can be increased by: increasing the number of turns on the […]
What is angular distance of Earth?
What is angular distance of Earth? The longitude of a point on the surface of the earth is the angular distance (λ) east or west from a reference line called prime meridian that runs from North Pole to South Pole. Being a reference line or origin for measuring angles, the prime meridian has a longitude […]
How does oxygen affect an ecosystem?
How does oxygen affect an ecosystem? Oxygen provides the most energy to plants, animals and microbes during respiration. However, when all of the oxygen in water or saturated soil has been consumed, some microbes can substitute other compounds for oxygen, including iron, manganese, nitrate and sulfate, in a process known as anaerobic respiration. What is […]
How does a pendulum work in a clock?
How does a pendulum work in a clock? A pendulum works by converting energy back and forth, a bit like a rollercoaster ride. When the bob is highest (furthest from the ground), it has maximum stored energy (potential energy). So as the bob swings (oscillates) back and forth, it repeatedly switches its energy back and […]
How can I tell if my alternator is bad?
How can I tell if my alternator is bad? 7 Signs of a Failing Alternator Dim or Overly Bright Lights. Dead Battery. Slow or Malfunctioning Accessories. Trouble Starting or Frequent Stalling. Growling or Whining Noises. Smell of Burning Rubber or Wires. Battery Warning Light on Dash. Can you test an alternator with a dead battery? […]
What is transposition in grammar?
What is transposition in grammar? Transposition. Transpositional grammar describes and analyzes movement in meaning across and between its different meaning-forms: text, image, space, object, body, sound and speech. Transpositional grammar is an account of meanings that, in their very nature, are always in a process of transformation. What is transposition and example? For example, 5x […]
Why external combustion engine is not used?
Why external combustion engine is not used? An external combustion engine is unique from other EHEs because it requires a fuel to undergo combustion to create the heat that is used for work. External combustion engines are no longer used in transportation, as mobile designs are not efficient enough, but they continue to be used […]
How do you get rid of coliform bacteria?
How do you get rid of coliform bacteria? First, if total coliform bacteria are found in a water sample, it indicates surface contamination (from construction or recent repairs) has reached the water and disease causing organisms may be present. Second, total coliform bacteria can be killed by disinfection, meaning chlorination or boiling of the water. […]
