Answer: naturalistic observation
Explanation: Naturalistic observation is a technique used in the study of subjects in their natural habitat without any manipulation or interference from the observer. The aim of naturalistic observation is to describe in detail the behaviour of an organism in their natural setting, situation or habitat.
Conducting a naturalistic observation offers some advantages which include:
I) allowing investigation of behaviours that occur in complex social settings.
II) allowing the researcher to gather qualitative as well as quantitative data and
III) allowing the development of theories based on collected observations etc.
However, it is less useful in studying well-defined hypotheses under precisely specified conditions since they are typically designed not to confirm previously formed hypotheses.
Answer:
a. Broca's area
Explanation:
Broca's area: Broca's area is found in the frontal lobe of an individual's brain and is involved in the eloquent aspects of the written and spoken language by a person. It is responsible for speech production and controls the motor functions which are involved in the process of producing a particular speech.
An individual who is dealing with the damaged Broca's area finds difficulty to put different words together while producing speech yet can understand the words.
In the question above, Bill's difficulty speaking is due to brain damage to Broca's area.
Answer:
2.84*10^-3 years = 0.00284*10^-3 years
Explanation:
To find the orbital period you use the following formula:

r: 2.0A = 2.0(1.5*10^11m)=3*10^11 m
G: Cavendish constant = 6.67*10^-11 Nm^2/kg^2
M: mass of the sun = 1.98*10^30 kg

Next, you calculate the time in seconds of one Earth's year:

thus, you use this value to find the orbital period of the asteroid in Earth's year:
