Answer:

Planck's constant is #h~~6.63*10^-34 \ "J"*"s"#.

Explanation:

Planck's constant, in science, is denoted by #h#, and is given the value of

#h~~6.63*10^-34 \ "J"*"s"#

Note that #1 \ "J"=1 \ "N"*"m"#

#=1 \ "kg"*"m/s"^2*"m"#

#=1 \ "kg"*"m"^2"/s"^2#

And so, we can rewrite #h# as

#h~~6.63*10^-34 \ "kg"*"m"^2"/s"^2*"s"#

#=6.63*10^-34 \ "kg"*"m"^2*"s"^-1#

This is one of the smallest constants in physics, and gives the relationship between a photon's energy and its frequency.
