(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.
Hence the the use of "cup" by the toddler to express his intent for a cup of milk is referred to as holophrases which is developmentally appropriate
Answer:
More than two million electron volts.
Explanation:
More than two million electron volts energy are needed to break or split a deuteron into a proton and a neutron. Nuclear binding energy is the type of energy that is required to split an atom's nucleus into protons and neutrons. The deuteron is an isotope of hydrogen that is composed of a proton and a neutron and it is a stable particle. Very huge amount of energy is needed for the splitting of nucleus due to the presence of heavy particles i.e. proton and neutron.
Answer:
Useful Output = 35 J
Explanation:
The useful energy output of the car must be equal to the difference between the total input energy supplied to the car and the energy wasted by the car:
Useful Output = Total Input - Waste
where,
Total Input = 120 J
Waste = 85 J
Therefore,
Useful Output = 120 J - 85 J
<u>Useful Output = 35 J</u>
Answer:
not realy
Explanation:
dancing is a way of exercise and liking a song or you're just happy etc.
Power = (energy) / (time)
= (1370 joules) / (100 seconds)
= 13.7 joules/second
= 13.7 watts .
That's not an awful lot of power, especially for a strenuous activity like
rock-climbing. Shoot ! Even I could probably perform at that level.
Compare 13.7 watts to the light power coming out of a 20-watt night light.
13.7 watts = 0.018 horsepower. (rounded)
