15 kilogram of the rock must be processed.
The two errors in the data resulting from an experiment where the temperature is raised too quickly are: First, the melting point temperature may not be recorded correctly since it cannot be monitored closely if the heat supplied is too high. <span />
Answer:
A
Explanation:
the tendency of a material to conduct heat or electricity can be detected on the outside
Answer:- Frequency is
.
Solution:- frequency and wavelength are inversely proportional to each other and the equation used is:

where,
is frequency, c is speed of light and
is the wavelength.
Speed of light is
.
We need to convert the wavelength from nm to m.
(
)

= 
Now, let's plug in the values in the equation to calculate the frequency:

=
or 
since, 
So, the frequency of the green light photon is
.
