Explanation / Answer

2000 and 499 in parallel 2000*499/(2000+499)399.4 in series

with 1000 =1399.4 =Req==>Itotal=IR1=5 V/1399.4 0.0035731 A or 3.5731 mA

VR1=0.00357*1000=3.5731 V==>voltage for the parallel circuit is

5 V-3.5731 V=1.4269 V==>IR2=1.4269 V/2000 =0.00071345 A

IR3=1.4269 V/499 =0.00286 A==>VR2=VR3=1.4269 V

PR1=I2*R=0.00357312*10000.01277 W==>PR2=I2*R=0.000713452*20000.00102 W

PR3=I2*R=0.002862*4990.004082 W
