Answer:
Explanation:
m1 = 24 kg
m2 = 63 kg
(a) Let the tension is T1 in upper rope and T2 in lower rope.
Use Newtons' second law on m2.
T2 = 856.8 N
Apply Newton's second law on m1
T1 = 1183.2 N
(b)
Use Newtons' second law on m2.
T2 = 378 N
Apply Newton's second law on m1
T1 = 522 N
Answer : The correct option is (A).
Explanation :
The relation between speed of sound and the density of medium is given by :
where
B is the bulk modulus
and is the density of the medium.
So, it is clear that the speed of sound is inversely proportional to the density of medium i.e.
The correct graph (A). From the graph it is clear that when density of medium approaches to zero, the speed of sound tends to infinite and vice versa.
