A) \[{{I}_{s}}\ge {{T}_{c}}\]
B) \[{{I}_{s}}\] and \[T_{c}^{2}\]
C) \[{{I}_{s}}\ge T_{c}^{1/2}\]
D) \[{{I}_{s}}\ge 1/{{T}_{c}}\]
Correct Answer: C
Solution :
When specific impulse is greater than critical temperature, then rocket blast takes place. So the condition \[{{I}_{s}}\ge T_{c}^{1/2}\] is right.
