The bowl of mixed fruits is a mixture because there are several things making up the object. Hence, option (B) is correct.
What is a mixture?
- The matter is categorized as mixtures and pure substances.
- A mixture is defined as a combination of substances that are not chemically mixed.
- A mixture can exist in solid, liquid, or gas form.
- A mixture can exist in the same or in a different phase. It can be homogenous or heterogeneous.
- If the substances are combined in the same phase, then the mixture is a homogeneous mixture.
- But if the substances are combined in different phases, then it is a heterogeneous mixture.
Therefore, the mixed fruit bowl is a mixture, because there are several things making up the object.
Hence, option (B) is correct.

<h2>
Answer: 8.93 g/cm³
</h2>
<h3>
Explanation:
</h3>
Density = mass ÷ volume
= 217.0 g ÷ 24.3 cm³
= 8.93 g/cm³
∴ the unknown sample of mass 217.0 grams and volume of 24.3 cm³ has a density of 8.93 g/cm³.
kg and all the given units are units used to measure mass.
kg is the standard unit to measure mass
lets find the value of 0.00684 kg in all the given units
a. dkg
1 kg is equivalent to 100 decagram (dkg)
therefore 0.00684 kg is = 100 dkg/kg x 0.00684 kg = 0.684 dkg
this is not the given value therefore this choice is incorrect
b. 1 kg is equivalent to 1000 g
therefore 0.00684 kg = 1000 g/kg x 0.00684 kg = 6.84 g
this is the given value so this is correct
c. 1 kg is equivalent to 100 000 centigrams (cg)
therefore 0.00684 kg = 100 000 cg/kg x 0.00684 kg = 684 cg
this is the given value so this is also correct
d) 1 kg is equivalent to 1 000 000 mg
therefore 0.00684 kg = 1 000 000 mg/kg x 0.00684 kg = 6 840 mg
this too is correct
the incorrect answer is A. 0.0684 dkg
Answer:
Water uses adhesive forces that allow it to stick to certain surfaces such as glass.
Explanation:
When the angle between vertical direction and the glass wall is small, surface tension is stronger and the component of gravity perpendicular to the glass wall is small. The result of this causes water to stick to the side of a glass.
Hope this helps!
