Answer: Keith and Aaron only
Explanation:
Since the school record for the 100-meter dash is 18 seconds, while
Juan did 19 seconds;
Hans did 16 seconds;
Keith did 17 seconds; and
Aaron did ILELE (unknown value)
Based on this illustration, only Keith and Aaron finished the 100-meter race at a lesser time than the school record.
Thus, Keith and Aaron only are the students that have broken the school record.
hey there!:
As El Tation is located at higher altitude than Old Faithful, the atmospheric pressure would be less at Ei Tatio.
Due to low pressure, the boiling point of water will be reduced at El Tatio. Hence, at lower temperature than Old Faithful, geysers will erupt at El Tatio due to depression of boiling point at reduced atmospheric pressure.
Hope this helps!
The time measured by a stopwatch is not an exact number. The number is limited by the precision of the instrument (the stopwatch) and it migh have been 56.004 instead of 56.00, and the stopwatch cannot shoe that. So, this is not an exact number.
Answer:
C2= 0.16M
Explanation:
C1= 2M, V1= 20ml, C2= ?, V2= 250ml
Applying dilution formula
C1V1= C2V2
2×20 =C2×250
C2= 0.16M
It is c) the energy that does work through chemical reactions
