A scientist noticed that a dark-colored peppered moth is more visible on a light-colored background than a light-colored peppere

d moth. He wonders, “Does this difference in visibility affect the survival rate of dark moths?” Which part of the scientific method does he need to carry out next?

Answer: Form a hypothesis

A scientific way to investigate a problem involves mainly five steps.

→A question or problem must be formulated in the first step.

→After gathering the background information, A hypothesis must be made.

→Third step would be to design an experiment.

→Fourth step would include collection and recording of data.

→Fifth step would include the conclusions drawn from the experiment and communication of hypothesis and its results.

When  the scientist notices that a dark colored peppered moth over light colored background, he formulates a question: whether the difference in visibility affects the survival rate of dark moths or not? Therefore, next step in the scientific method would be to gather more information on the subject and formulate a hypothesis.

suppose the same amount of heat is applied to two bars. they have the same mass, but experience different changes in temperature
Andreyy89

If both bars are made of a good conductor, then their specific heat capacities must be different. If both are metals, specific heat capacities of different metals can vary by quite a bit, eg, both are in kJ/kgK, Potassium is 0.13, and Lithium is very high at 3.57 - both of these are quite good conductors.

If one of the bars is a good conductor and the other is a good insulator, then, after the surface application of heat, the temperatures at the surfaces are almost bound to be different. This is because the heat will be rapidly conducted into the body of the conducting bar, soon achieving a constant temperature throughout the bar. Whereas, with the insulator, the heat will tend to stay where it's put, heating the bar considerably over that area. As the heat slowly conducts into the bar, it will also start to cool from its surface, because it's so hot, and even if it has the same heat capacity as the other bar, which might be possible, it will eventually reach a lower, steady temperature throughout.

A piano tuner is using a 392 Hz tuning fork to tune the wire for a G-Natural note. She hears 4 beats per second. What are the tw
inysia [295]

A beat is an interference pattern between two sounds of slightly different frequencies, perceived as a periodic variation in volume whose rate is the difference of the two frequencies. Frequency beat is equal to,

f_{beat} =| f_2\pm f_1 |

The reference frequency in our case would be 392Hz, and since there is the possibility of the upper and lower range for the amount of beats per second that the two possible frequencies are heard would be

f_{beat} =|392+4|= 396Hz

f_{beat} =|392-4|=388Hz

Therefore the two possible frequencies the piano wire is vibrating at, would be 396Hz and 388Hz
