What is jump on carry in 8085?
Jump on Carry is simply a "JUMP" instruction which will transfer the control to some specific location if carry flag is set. For Example: JC 2004H This instruction will take the control to address location 2004H if carry flag is set.

Which is the longest instruction in 8085 instruction set?
CALL, requiring 18 clock cycles.
How do you clear carry flag in 8085?
You can clear carry by using these two commands STC // it will force to set the carry flag CF=1// CMC //it willl complement that carry and you have done, CF=0 // in single instruction u can reset carry by using any logical instruction. because logical operation resets carry always... eg. XRI 00h or ANI 0F Geniusminds.com
