Explain the process behind the scientific method and how it has the potential to lead to a "feedback loop".
Nina [5.8K]
Scientific method is a process wherein there is a common end result at the end of each milestone of the research. This is to improve the problem which was intended to be realized at the beginning of conducting or applying scientific method. The feedback loop is the part of the model which allows for continuous improvement of the method, for each result there may be atleast known and observed result analysis which is feedback to a step or the whole process for the betterment of the cycle.

const2013 [10]

The physical evidence are the silent witnesses against the perpetrators of a crime

The correct option of what the field inspector packages after the crime scene has been photographed is the option;

  • <u>Physical evidence</u>

Reason:

Physical evidence are evidence that originate from inanimate objects or origin that is nonliving, and includes every material or object that serve as an indicator that someone has committed a crime, or that can link a perpetrator to crime

Examples include; Documents, hair, skin, fingerprints, weapons, soil, or fibers

The field inspector, collects the evidence that shows that a crime has been committed which are the physical evidence, after the crime scene has been photographed

How much heat transfer (in kcal) is required to raise the temperature of a 0.850 kg aluminum pot containing 2.00 kg of water fro
hram777 [196]

To solve this problem we will apply the concept related to the heat transferred to a body to reach a certain temperature. This concept is shaped by the energy ratio of a body which is the product of the mass, its specific heat and the change in temperature. For the specific case, it will be the sum of the heat transferred to the Water, the Aluminum and the loss due to latency due to vaporization in the water. That is to say,

\Delta Q = m_{Al} C_p \Delta T +m_wC_w \Delta T  +m_w L_v

Here,

m_{Al}= Mass of Aluminum

C_p= Specific Heat of Aluminum

C_w= Specific Heat of Water

m_w = Mass of water

L_v =Latent of Vaporization

Replacing,

\Delta Q = (0.85)(900)(100-45)+(2)(2000)(100-45)+(0.7)(2258000)

Converting,

\Delta Q = 1842675J (\frac{0.000239006kCal}{1J})

\Delta Q = 440.409kCal

Therefore is required 440.409kCal
