Answer:
The value is
Explanation:
From the question we are told that
The temperature is
Generally the root mean square speed of the oxygen molecules is mathematically represented as
Here R is the gas constant with a value
M is the molar mass of oxygen molecule with value
So
=>
Answer:
The specific gravity of the unkown liquid is 15.
Explanation:
Gauge pressure, at the bottom of the tank in this case, can be calculated from
where and
are the height of the column of oil and the unkown liquid, respectively. Writing for
, we have
Relative to water, the unknow liquid specific weight is 15 times bigger, therefore this is its specific gravity as well.
