The answer to this question is option 2
Answer:
For diatomic oxygen:V=539.06 m/s
For carbon dia oxide:V=459.71 m/s
For dia atomic hydrogen:V=2156.25 m/s
Explanation:
As we know that
Root mean square velocity V
Where
R is the gas constant
T is the temperature (K).
M is the molecular weight.
For diatomic oxygen:
M=32 g/mol
T=273+100 = 373 K
V=539.06 m/s
For carbon dia oxide
M=44 g/mol
T=273+100 = 373 K
V=459.71 m/s
For dia atomic hydrogen:
M= 2 g/mol
T=273+100 = 373 K
V=2156.25 m/s
By conservation of momentum,
Distance lighter fragment slide= 7*6.7=46.9m
Answer:
Parameter is population mean = 65 c
Explanation:
There are two important aspects in the study of samples and inferring the behaviour of population.
TO know the mean of the population, normally we draw different samples and find their mean. The mean of all means will be an estimate for the populatio mean. By central limit theorem, mean of a sample tends to be normal as sample sizes grow with estimated mean as mean of sample.
While a statistic describes a sample, a parameter describes an entire population.
Here 65 degrees C is for entire population hence this is a parameter.
