Answer: The frequency of the green light emitted by a hydrogen atom with a wavelength of 546 nm is 
.
Explanation:
Given: Wavelength = 546 nm 
= 
The relation between frequency and wavelength is as follows.
where,
= frequency
c = speed of light = 
= wavelength
Substitute the values into above formula as follows.
Thus, we can conclude that the frequency of the green light emitted by a hydrogen atom with a wavelength of 546 nm is .
Answer:
B
Explanation:
Temperature & pressure are directly proportional
The neutrons take up most of the space of an atom
The Rivergate because you are basing the distance off of there
statement about enzymes that is correct is
b. they are large molecules that increase the rate of biologically important reactions
Enzymes are proteins that catalyse, in other words increase the rate of the biological reactions.
Biological functions that are vital for the bodies to survive, have large activation energy barriers. For this reason enzymes are used that reduce the activation energy required for the reaction to initiate. this enables the reactions to proceed.
Substrates bind to the enzyme, reaction occurs and substrate converts to products, that are released from the enzyme, leaving the enzyme unchanged.
so the correct answer is B.
