You are moving towards Qutab Minar. Is Qutab Minar at rest or in motion with respect to you?

You are given a red flower bearing flower plant and a red flower bearing snapdragon plant. How would you find the genotypes of these two plants with respect to colour of flower?

Explain this common observation clearly : If you look out of the window of a fast moving train, the nearby trees, houses etc. seem to move rapidly in a direction opposite to the train’s motion, but the distant objects (hill tops, the Moon, the stars etc.) seem to be stationary. (In fact, since you are aware that you are moving, these distant objects seem to move with you).

You have been given two cans with capacities 9 and 5 liters respectively. There is no graduation marks on the cans nor is eye estimation possible. How can you collect 3 litres of water from a tap? ( you are allowed to pour out water from the can). If the cans had capacities 8 and 6 litres respectively, could you collect 5 liters?

You have been provided with three test tubes one of them contains distilled water and the other two contain an acidic solution and a basic soution respectively . If you are given only red litmus paper, how will you identify the contents of each test tube?

What will you hear if you were to move away from a siren with speed of sound?

A wheel in uniform motion about an axis passing through its centre and perpendicular to its plane is considered to be in mechanical (translational plus rotational equilibrium because no net external force or torque is required to sustain its motion. However, the particles that constitute the wheel do experience a centripetal acceleration directed towards the centre. How do you reconcile this fact with the wheel being in equilibrium? How would you set a half - wheel into uniform motion about an axis passing through the centre of mass of the wheel and perpendicular to its plane? Wil you require external forces to sustain the motion?
