Answer:
35.9%
Explanation:
The percent volume of the coffee solution can be calculated as follows:
% volume of coffee solution = volume of coffee/total volume of coffee solution × 100
According to this question, a cup of coffee has 71 mL of coffee and 127 mL of water. This means that, the total volume of coffee solution is;
71mL + 127mL = 198mL
% volume = 71/198 × 100
= 0.359 × 100
Percent volume of coffee solution = 35.9%
Answer:
The highest sea-level pressure on Earth occurs in Siberia
Explanation:
where the Siberian High often attains a sea-level pressure above 1050 mbar (105 kPa; 31 inHg), with record highs close to 1085 mbar (108.5 kPa; 32.0 inHg).
Answer:
Time = 4.2273 seconds
Explanation:
The amount of the energy emitted by the microwave = 1100 J/s
It means that :
1100 J of the energy is emitted in 1 second
Also,
1 J of the energy is emitted in [tex]\frac {1}{1100}[tex] second
To calculate:
Time for emitting 4650 J of energy
Thus,
4650 J of the energy is emitted in [tex]\frac {1}{1100}\times 4650[tex] second
<u>Time = 4.2273 seconds</u>
