A Bullet weighing 4.5 × 10-³kg is fired horizontally into a 1.8kg wooden block at rest on a horizontal surface. The coefficient of the kinetic friction between block and surface is 0.20 the bullet comes to rest in the block which moves 1.8m, find the speed of the bullet​

i believe the answer is a hope it and is correct

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
