Answer:
It depends, seeing as some people prefer to call this group toddlers, while others call them preschoolers with an age range of 3-5. Most of the people I know call the age group 2-4 toddlers, but as I said depends on how you think about it. I consider toddlers to be <em>between </em>3-4 years of age, but not <em>all </em>toddlers. So in my opinion, this would be true.

Explanation:
10Khs equals to 10,000Hz/10Khz/0.01Mhz/0.00001Ghz
Answer:
Q= 6491.100 kJ/s
Explanation:
Air-Fuel Ratio:
For a combustion reaction the proportion of air that is present in a gaseous substance responsible for the reaction,this proportion is known as air-fuel ratio.The air fuel ratio is calculated using the combustion reaction for the substance.
Considering reaction for the Ethanol as
C₂H₅OH +XO₂(O₂+3.76N₂)→ aCO₂+bH₂O+cN₂
Balancing the equation we get;
a=2,
2b=6
∴ b=3
xO₂=3
The air-fuel ratio
A/F = XO₂+H₂O+xN₂× mass of N₂/mass(fuel)
3.31×31.9+11.28×28.013/46.069
= 8.943
Equivalent ratio = 0.7,
so, heat transfer
Q= m ×Cp×ΔT
= 75×0.7×112.4(1500-400)
Q= 6491.100 kJ/s
1kJ/s=1000w
∴ Q= 6491100 W
