US Letter is a paper size, which measures:
8.5 inches ( width ) by 11.0 inches ( length ).
8.5 inches = 21.59 cm
11.0 inches = 27.94 cm
The length ( 27.94 cm ) is closest to 29 cm.
Answer:
C ) 29 cm
Answer:
even though I am missing the question I believe that the correct answer to the question is; <em>his cats will be brown (Dominant)</em>
Explanation:
this statement is true to the fact that on of his cats has the homozygous dominant gene BB. For their to be a chance of a white cat as an offspring both cats would either have to be Hetrozygous (Bb) or Homozygous recesssive (bb)
Answer:
<u>225.6 kJ</u>, <em>assuming the water is already at 100 °C</em>
Explanation:
The correct answer to this question will depend on the initial temperature of the water to which heat is added to produce steam. Energy is required to raise the water temperature to 100°C. At that point, an energy of vaporization is needed to convert liquid water at 100 °C to water vapor at 100°C. The heat of vaporization for water is 2256.4 kJ/kg. The energy required to bring 100g of water from a lower temperature to 100°C is calculated at 4.186 J/g°C. We don't know the starting temperature, so this step cannot be calculated.
<em><u>Assuming</u></em> that we are already at 100 °C, we can calculate the heat required for vaporization:
(100.0g)(1000.0g/1 kg)(2256.4 kJ/kg) = 225.6 kJ for 100 grams water.
