Answer: 8*5≥c
sorry if wrong! Not my strong suit !
Answer:
Step-by-step explanation:
It's easier to convert the angle into degrees.
5π/8 ≅ 112.5°, which is in quadrant II
Obj B, by 1 g/cm^3
Obj A = 12g / 8cm^3 = 3g / 2cm^3 = 1.5 g/cm^3
Obj B = 20g / 8cm^3 = 5g / 2cm^3 = 2.5 g/cm^3
2.5 - 1.5 = 1 g/cm^3
90
