(d) option is right answer
Answer:
acceleration a= 0.1344 m/sec^2
Explanation:
Given
mass of the object m= 72 kg
Force applied with help of rope= 358 N
Acceleration due to gravity= 9.81 m/sec^2
Since there is no force acting on the person and rope
then T=F
and from the FBD we can write
2T- mg= ma ,or
2F- mg= ma
now putting the values we get
on calculating we get acceleration a= 0.1344 m/sec^2
A boiling pot of water (the water travels in a current throughout the pot), a hot air balloon (hot air rises, making the balloon rise) , and cup of a steaming, hot liquid (hot air rises, creating steam) are all situations where convection occurs.
