VThis section also demonstrates your understanding of the experiment, through your ability to offer constructive criticism about

its design and make suggestions for future experimentation. There are always ways that experiments can be improved. Now that you are a veteran of this experiment and have experience with the procedure, offer some advice to the next scientist about what you suggest and why.

Hello. You did not say what is the experiment to which this question refers, which makes it impossible for it to be answered accurately.

However, advice that should be given to anyone who should start an experiment is: establish a control treatment, provide all treatments with the same variables and the same resources, write down everything that happened in the experiment from implementation to data collection and results, make measurements and analyzes on the same date in all treatments and keep the steaks in the same environment.

Compared to infrared radiation, an electromagnetic wave that has a lower frequency will also have a ________.
IgorLugansk [536]

Answer:

  • <u><em>B. longer wavelength and equal speed </em></u>

Explanation:

One important feature fo <em>electromagnetic radiation</em> is that all have the same speed in vacuum, <em>c</em><em>,</em> in vacuum, which is the speed of light.

Since, the speed, wavelength and frequency of the waves are related you can infere any of them when the other two are known.

The equation is:

  • speed = frequency × wavelength
  •     s     =          ν        ×      λ
  •     c     =          ν        ×      λ      . . . for the specific case of electromagnetic radiation

That inverse relation between frequency and wavelength, where the speed is the constant, shows that the lower the frequency the longer the wavelength.

In conclusion, the correct statment is that an <em>an electromagnetic wave that has a lower frequency will also have a longer wavelength and equal speed (option B).</em>

Making a pancake from batter is an example of blank change
lesantik [10]

Answer is: chemical.

Making a pancake from batter is chemical change (chemical reaction), because new substances are formed, the atoms are rearranged and the reaction is followed by an energy change.

Batter is thin dough that is poured into a pan to make pancakes.

In physical change, the same substance is present before and after the psysical change, just with different form or state of matter.
