The correct answer would be that substance A is rice, and substance B is sugar.
For substance A to be filtered out, it means that A is a water-insoluble substance and for substance B to be recoverable by evaporating off the water, it means that B is water-soluble.
Thus, A can neither be sugar nor alcohol because neither can be recovered by filtration. Also, B can neither be coffee nor alcohol because they can not be recovered as residue through evaporation of water.
Therefore, the only correct answer is that substance A is rice, and substance B is sugar because rice can be filtered out from water while the water-soluble sugar can be recovered by evaporating the water.

Answer:
e.the ball exerts more force because it is smaller
The regression equation is:
y = 1.15 – 0.251 x₁ + 0.078 x₂ + 0.306 x₁x₂

Where,
x₁ = -0.2508
x₂ = 0.0777
x₁x₂ = 0.3058
Inserting the values,
<span>
<span>
</span></span>y = 1.15 – {0.251 × (-0.2508)} + {0.078 ×(0.0777)} + {0.306 × (0.3058)}
</span></span></span>
y = 1.15 - (- 0.0629508) + 0.0060606 + 0.935748
y = 1.15 + 0.0629508 + 0.0060606 + 0.935748
y = 1.3125862
Answer:
