From what height must a block of ice fall to just melt by the impact assuming that half of the heat generated is absorbed by ice? (`J=4.2` joules per calories and `L=80` kilocalories per kg)

From what height must a block of ice be dropped in order that it may melt completely. It is assumed that the whole of energy is retained by ice. Given that latent heat of ice = 80 cal g^(-1) .

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) .

What is the horse power applied by a person while chewing 100g of ice per minute ? Given J = 4.2 joule per calorie.

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) )

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 55.0 kg ice skater moving at 8.5 m/s glides to a stop. Assuming the ice is at 0^(@)C and that 50 percent of the heat generated by friction is absorbed by the rice, how much ice melts?

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 hight 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 heat during its fall. The value of h is : (Latent heat of ice is 3.4xx10^(5) j//kg and g=10N//kg )
