C. As the bird of mass 'm' accelerating upwards with acceleration 'a' apparent weight(R) of the cage becomes R-mg=ma. R=mg+ma.since R is greater than weight of the bird (mg) the weight of the cage increases.here apparent weight(R) is the reaction exerted by the surface of contact on the bird.
If a parrot starts flying upwards with an acceleration in an air tight...
Explanation:
When a parrot starts flying upwards with an acceleration in an airtight cage, the weight experienced by the boy will be affected due to the laws of physics. The weight of the cage is the force exerted by the cage on the boy due to gravity.
Newton's Second Law of Motion:
According to Newton's second law of motion, the force exerted on an object is directly proportional to its mass and acceleration.
Impact on Weight of the Cage:
When the parrot starts flying upwards with an acceleration, it exerts an upward force on the cage. As per Newton's second law of motion, the cage will also experience an upward acceleration due to the force exerted by the parrot. This upward acceleration of the cage will reduce the force exerted by the cage on the boy, which, in turn, reduces the weight felt by the boy.
Therefore, the weight of the cage felt by the boy will be reduced when the parrot starts flying upwards with an acceleration in an airtight cage.
Answer:
The correct answer is (b) reduced.
