A block of ice falls from certain height and completely melts. If only 3/4th of the enrgy is absorbed by the block. The height of the fall should be (L=363SI units and `g=10ms^(-2)`)

Hailstones fall from a certain height. If they melt completely on reaching the ground, find the height from which they fall.

From what heigh should a piece of ice fall so that it melts completely ? Only one quarter of the heat produced is absorbed by the ice. Latent heat of ice is 3.4xx10^(5) j kg^(-1) and g=10 ms^(2) .

A piece of ice falls from a heighth so that it melts completely. Only one-quarter of the heat produced is absorbed by the ice and all energy of ice gets converted into heat during its fall. The value of height from which ice fall . [Latent heat of ice is 3.4 xx 10^(5) J//kg and g = 10 N/kg]

A piece of ice falls from a height h so that it melts completely. Only one-quarter of the heat produced is absorbed by the ice and all energy of ice gets converted into heal during its fall. The value of h is [Latent heat of ice is 3.4 xx 10^5 J/kg and g=10 N/kg ]

A piece of ice falls from a height h so that it melts completely .Only one-quarter of the heat produced is absorbed by the ice and all energy of ice get converted into heat during its fall.The value of h is [Latent heat of ice is 3.4xx10^5 J//K and g =10N//Kg ]

Hail stonces fall from certain height. If only 2% of the mass of the hail stone melt on reacting the ground,, the height from which they fall is ( g = 10 ms^(-2) , L = 80 cal/gm and J = 4.2J/cal)

A piece of ice falls from a height h so that it melts completely. Only one-quarter of the heat produced is absobed by the ice and all energy of ice gets converted into heat during its fall. The value of h is [Latent heat of ice is 3.4 xx 10^(5) J//kg and g = 10 N//kg ]

A piece of ice falls from a height h so that it melts completely. Only one-quarter of the heat produced is absobed by the ice and all energy of ice gets converted into heat during its fall. The value of h is [Latent heat of ice is 3.4 xx 10^(5) J//kg and g = 10 N//kg ]
