thank you for asking to answer
the defect of vision he is suffering from is myopia this can be answered by looking into the negative signs of focal length and the correction of this defect is by concave lens of suitable power.
the power of lens can be calculated by
the formula equal to 1 /f(in m)
so you are answer will be-0.6 D Here D is diopters.

Answer:
Explanation:When an object falls freely towards the ground, its potential energy decreases and kinetic energy increases.
As the object touches the ground, all its potential energy gets converted into kinetic energy.
As the object hits the hard ground, all its kinetic energy gets converted into heat energy and sound energy.
It can also deform the ground depending upon the nature of the ground and the amount of kinetic energy possessed by the object.
