Answer:
0.4 * 10^-12 m
Explanation:
Frequency of the given Electromagnetic radiation is 7.50* 10^20 Hz
Speed of the electromagnetic radiation is 3*10^8 m/s
Hence wavelength is given by the formula: Speed/Frequency
Substituting the required values:
Wavelength = 3 * 10^8/7.50 * 10^20
=3/7.5 * 10^-12 = 0.4 * 10^-12 m
Hence the required wavelength of the electromagnetic radiation is 0.4*10^-12 m/s
The correct answer is industrial smog. This type of smog exists in coal power plants which creates smoke and sulfur dioxide which may mix with fog creating a thick blanket of haze. Sulfur dioxide is one primary component of an industrial smog.
C. Crystalilozation followed by exposure and weathering
Answer:
High tides and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. ... When you're not in one of the bulges, you experience a low tide.
Answer:
200 g/L
Explanation:
The concentration of a solution (also called molarity) can be calculated with the formula:
where
m is the mass of the solute
V is the volume of the solution
For the solution in this problem we have:
m = 50g is the mass of the solute
V = 250 mL = 0.250 L is the volume of the solution
Therefore, the concentration of the solution is:
