Which of the following measurements is expressed to three significant figures?
C. 5.60 km
Hope this helps!
Just find the energy of the <span>blueviolet light with a wavelength of 434.0 nm using the formula:
E = hc / lambda
E = energy
c= speed of light = 3 x 10^8 m/s
h = planck's constant = 6.6 x 10^{-34} m^2 kg / s
lambda = 434 nm = 434 x 10^{-9} m
Putting these values (with appropriate units) in the above formula :
we get: Energy, E = 4.5 x 10^{-19} J
E = 0.45 x 10^{-18} J
Now, the </span>minimum energy is 2.18×10^-{18} J but our energy is 0.45 x 10^{-18} J which is less.
<span>Means the electron will not be removed

Answer:
C. natural gas
Explanation:
Solar comes from the sun, which if it became nonrenewable, we would be dead. hydroelectric comes from water and Dams, which water is reproduced through rain. Biomass are things like leaves, which are seasonally reproduced.
