How did Robert Boyle show experimentally that a coin and a piece of paper when dropped simultaneously from same height in vacuum fall with same acceleration ?

How did Robert proved experimentally that all bodies fall in vacuum with same acceleration?

Galileo's experminet showed that if the two objects of unequal masses are dropped from the sme height in vaccum,the times required by tehm are equal to reach the ground.But,if they are shown vertically upwards in vaccum with the same initial velocity what is the ratio of the times required to reach the ground?

Height of 50 plants in a garden were recorded and data is presented as below: Draw ‘less than’ ogive and ‘more than’ ogive simultaneously on the same graph and find the median of the data from graph. Also verify your result by using formula.

Two spherical bobs, one metallic and the other of glass, of the same size are allowed to fall freely from the same height above the ground. Which of the two would reach earlier and why?

How much momentum will a dumb-bell of mass 10 kg transfer to the floor if it falls from a height of 80 cm ? Take its downward acceleration to be 10 ms ^(-2) .

The figure SAQ 14(a) shows two identical rectangular loops (1) and (2) placed along with a straight long current carrying conductor between them. What will be the direction of induced currents in the loops when they are pulled away from the condutor with the same velocity v?
