The frequency of the yellow light is 
Explanation:
The relationship between wavelength, frequency and speed of a wave is given by the wave equation:
where
v is the speed of the wave
f is the frequency
is the wavelength
For the yellow light in this problem, we have:
is the speed
is the wavelength
Solving for f, we find its frequency:

When fossil fuels are burnt, what 2 gases are given off?
When fossil fuels are burnt, the following are one of the two gases when they are given off:
→ Carbon dioxide: Carbon dioxide is a green house gas, and plays a major role in the global warming.
→ Carbon Monoxide: Carbon monoxide is a gas that is dangerous to human beings when released.
Hope I helped (:
Have a great day!
Is there any possible chance that at some point in your science
studies, sometime before you were given this question for your
homework, that maybe you might have encountered this formula
for the period of a simple pendulum ?
Period = (2 pi) √(length/gravity) .
If the length is 0.23 meter, and the
acceleration of gravity is 9.8 m/s²,
then the period is
= (2 pi) √(0.23/9.8)
= 0.963... second (rounded)
That's how long it takes for a simple pendulum, 23cm long,
hanging on a massless string and not swinging too far to
the side, to complete one full swing left and right.
Now, if you can figure out how many periods of 0.963 second
there are in 30 seconds, you'll have your answer. I'll leave
that part of it to you.
Plant and animal life, atmosphere and water are the major causes of weathering .
