An apprentice bricklayer stabs 30cm long blocks on top of each other in such a way that 5cm of each block hangs over the lower block. How many blocks can he stack before the system collapse? Assuming that the block have equal masses

Explanation:The work done is twice as great for block B because it is moved twice the ... Equal forces are used to move blocks A and B across the floor. ... Does the normal force of the floor pushing upward on the block do any work? ... Suppose that the mass is halfway between one of the extreme points of its motion and the center point.

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right
