Answer:
6.56×10¹⁴ Hz
Explanation:
From the question given above, the following data were obtained:
Wavelength = 457 nm
Frequency =?
Next, we shall convert 457 nm to metre (m). This can be obtained as follow:
1 nm = 1×10¯⁹ m
Therefore,
457 nm = 457 nm × 1×10¯⁹ m / 1 nm
457 nm = 4.57×10¯⁷ m
Thus, 457 nm is equivalent to 4.57×10¯⁷ m
Finally, we shall determine the frequency of the blue light as follow:
Wavelength = 4.57×10¯⁷ m
Velocity of light = 3×10⁸ m/s
Frequency =?
Velocity = wavelength x frequency
3×10⁸ = 4.57×10¯⁷ × frequency
Divide both side by 4.57×10¯⁷
frequency = 3×10⁸ / 4.57×10¯⁷
frequency = 6.56×10¹⁴ Hz
Therefore, the frequency of the blue light is 6.56×10¹⁴ Hz
Assuming the person has about 154 pounds (70kg) the weight of an average human. There would be around 7000000000000000000000000000 atoms
or 7 x 10^27
Answer:
The balanced equation of H2 + Cl2 —-> HCl is 2H2 + 2Cl2 —-> 2HCl.
Explanation:
In a chemical reaction, the number of atoms of each element must be the same on both sides of the equation. In this case, there are two atoms of hydrogen on the left side and two atoms of chlorine. On the right side, there is one atom of hydrogen and one atom of chlorine. In order to balance the equation, we must add another chlorine atom to the right side so that there are two atoms of chlorine on both sides of the equation. The final balanced equation is 2H2 + 2Cl2 —-> 2HCl.
Hello,
The answer should be "thermal energy".
Reason:
The answer is thermal energy because the heat from whatever source the person is energy is transferring heat to the chicken which is causing the chicken to cook therefore the answer is thermal (heat) energy.
