Hello there.
<span>6. The specific heat capacity of aluminum is 0.22 cal/g°C. How much energy needs to flow into 20.0 grams of aluminum to change its temperature by 15°C?

Answer:
Research bias or Experimenter bias
Explanation:
Research bias or Experimenter bias is the phenomena that results when the researcher's preferences or hopes about the result influences the obtained outcomes.
This can also be explained as a result of the unconscious and subjective effect of the researcher's hopes on the data used in an experiment or the participants of the experiment or the outcome of the related experiment.
This can be avoided by the researcher by paying attention to the records made by the participants of the experiment and not based the outcome of the experiment on the basis of the his thinking.
If a = 2.0 cm, b = 5.0 cm, and i = 20 a, 6.0 μt is the magnitude of the magnetic field at the point p, So the correct option is (a).
The magnetic influence on moving electric charges, electric currents, and magnetic materials is described by a magnetic field, which is a vector field. A force perpendicular to the charge's own velocity and the magnetic field acts on it when the charge is travelling through a magnetic field.

i 
/ 
= μ i / 
As, is moving down and is moving up so,
- = (μ i / ) - [μ i / ]
- = μ i 24 / 
- = 
- = 5.98×
T ≈ 6μT
Therefore, 6.0 μt is the magnitude of the magnetic field .

I'd say an insulator
Hope this helps!!!
