(a) cognitively impaired (b) using holophrases which is developmentally appropriate (c) language-delayed and needs professional assistance (d) trying to manipulate his father and needs to be disciplined
The correct answer is (b) using holophrases which is developmentally appropriate
Explanation:
Holophrases are one of the single-word utterances characteristic of children in the early stages of language acquisition, it is the use of a single word to express a complex idea. Holophrases are normal among toddlers within the age of two years below.

Answer:
The focal length of eyepiece is 3.68 cm.
Explanation:
Given that,
Distance = 19 cm
Focal length = 5.5 mm
Magnification = 200
Object distance = -25 cm
We need to calculate the focal length
Using formula of magnification
Put the value into the formula
Hence, The focal length of eyepiece is 3.68 cm.
Answer:
First of all the formula is F= uR,( force= static friction× reaction)
mass= 5+25=30
F= 50
R= mg(30×10)=300
u= ?
F=UR
u= F/R
u= 50/300=0.17N
Ventilation is very important because it helps remove the gas form people’s homes and schools and it redirects the random gas outside so it is less likely to hurt people
