Answer:
Distance cover by school bus = 149.5 miles
Explanation:
Given:
Velocity of school bus = 65 mph
Time taken by school bus = 2.3 hours
Find:
Distance cover by school bus
Computation:
Distance cover = Velocity x Time taken
Distance cover by school bus = Velocity of school bus x Time taken by school bus
Distance cover by school bus = 65 x 2.3
Distance cover by school bus = 149.5 miles
Conjugate base of Propanoic acid ( is propanoate where -COOH group gets converted to -CO. The structure of conjugate base of Propanoic acid is shown in the diagram.
The above which 90% of the compound will be in this conjugate base form can be determined using Henderson's equation as propanoic acid is weak acid and it can form buffer solution on reaction with strong base.
= + log=4.9+log=5.85
As 90% conjugate base is present, so propanoic acid present 10%.
Answer:
The light emitted by a light bulb is a form of radiation that occurs when the filament heats up and its thermal emission gains enough energy to move into the visible spectrum.
Explanation:
Light bulbs contain a filament which is heated up electrically. When this filament is heated up,energy in the form of heat is imparted to the electrons in the filament.
This thermal excitation of electrons ultimately leads to emission of light in the viable spectrum. This light is now radiated through a light bulb.
Answer:
Respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce use able cellular energy. This energy is used to fuel growth and all of the normal cellular functions.
Short Answer
They combine to produce cellular energy.
