Asmall logo is embedded in a thick block of crown glass (n = 1.52), 4.70 cm beneath the top surface of the glass. the block is put under water, so there is 1.70 cm of water above the top surface of the block. the logo is viewed from directly above by an observer in air. how far beneath the top surface of the water does the logo appear to be?

3. a worker pushes a 30.5 kg polished stone along a polished table with a force on bonin a straight line for 5.20 s after starting from rest. there is no friction between thestone and the table. at the end of the table. the stone is hooked to a cable with a lengthof 62.0 cm to rotate it to a rough table to store until they can be picked up. the roughtable has a coefficient of static friction 0.702 with the polished stone. remember that 8= 9.80 m/s2a) what is the speed of the stone when it is hooked to the cable? b) what is the tension in the cable while the stone is rotating? (there is still nofriction)c) how much force is needed to make the stone begin sliding from rest on therough table? ius = 0.70262.0 cm30.5 kg20.5 kg6= 0
