Answer:
D. One dependent variable and one experimental variable
Explanation:
The experimental variable is defined as an independent variable which can be manipulated during an experiment in order to find out its impact or influence on the dependent variable.
The dependent variable refers to a variable that changes when an experimental or independent variable is manipulated.
Every experiment must have at least one experimental variable and one dependent variable in order to yield any meaningful result.
Answer: 5. Determine the number of atoms that are in 0.58 mol of Se. 0.58molo se x 6.02x1020 g tors Se - 3.5X1023 atoms Se 1 mol of Se 6.
Explanation:
Answer: longer wavelength and lower energy.
Explanation:
1) The wavelength is inversely related to the frequency. So, an electromagnetic wave with lower frequency will have longer wavelength.
This is the formula for electromagnetic waves:
λ = c / ν
where λ is the wavelength, c is the speed of light, and ν is the frequency.
2) Energy is directly related to the frequency.
This is the formula E = hν,
where E is the energy, h is Planck constant, and ν is the frequency.
So, the lower the frequency the lower the energy.
3) Conclusion:
<span>An electromagnetic wave that has a lower frequency than infrared radiation will have longer wavelength and lower energy than the infrared radiation</span>
Answer:
Yes
Explanation:
Thermal radiation is emitted by any surface having a temperature higher than absolute zero. So the short answer to your question is yes. Light (electromagnetic radiation) of any frequency will heat surfaces that absorb it.
