The weight of the aluminum foil is 26.20 N
To find the weight of the aluminum foil when it is unrolled, we need to find its volume.
The volume V = lwt where
- l = length of aluminum foil = 22 m,
- w = width of aluminum foil = 30 cm = 0.30 m and
- t = thickness of aluminum foil = 0.15 mm = 0.15 × 10⁻³ m.
So, V = lwt
= 22 m × 0.30 m × 0.15 × 10⁻³ m
= 0.99 × 10⁻³ m³.
So, its weight W = ρV where
- ρ = specific weight of aluminum = 26460 N/m³ and
- V = volume of aluminum foil = 0.99 × 10⁻³ m³
So, W = ρV
W = 26460 N/m³ × 0.99 × 10⁻³ m³
W = 26195.4 × 10⁻³ N
W = 26.1954 N
W ≅ 26.20 N
So, the weight of the aluminum foil is 26.20 N

Answer:
Yes
Explanation:
Each person has two alleles (forms of a gene) for a characteristic. We can represent them using letters.
Dominant trait are written as capitals. If a dominant allele is present in someone's genotype, the dominant trait will show.
The recessive trait only shows if a person has two recessive alleles.
Brown eyes is a dominant trait, and blue eyes is a recessive trait.
B = dominant brown eyes
b = recessive blue eyes
If someone has <u>brown</u> eyes, their genotype can be:
BB
Bb
If someone has blue eyes, their genotype is:
bb
The baby's genotype must be bb because it has blue eyes. <u>The baby gets one allele from each parent</u>.
See the photo for Punnett square. If the parents are both Bb, then they could each give the b allele, resulting in a blue-eyed baby.

Answer:
:Electric charge is a basic property of electrons, protons and other subatomic particles. Electrons are negatively charged while protons are positively charged. ... Things that have the same charge push each other away (they repel each other). This is called the Law of Charges.
