level shifter

The contents of a 8-bit register is initially 01110111. The register is shifted right six times with the serial input being 011001. The same register is then shifted left 4 times with the serial input being 0101. What is the final contents of the register?

Voltage Source V2 is managed between 0 and 5V,So how does the voltage vary at point 4 or across the 3 ohm resistor
