C) the scientific method because if we look at the scientific method in detail, this is what we get:

Step 1: Make an Observation.
Step 2: Form a Question.
Step 3: Form a Hypothesis.
Step 4: Conduct an Experiment.
Step 5: Analyse the Data and Draw a Conclusion.

Calculate the weight of an object of 30 kg on Earth. 2. Calculate the weight of an object of 30000 g on Earth. 3. Calculate the

Dima020 [189]

Answer:

1. 294N

2. 294N

3. 19.6N

4. 19.6N

5. 4.9N

6. 4.9N

7. 80N

8. 185N

Explanation:

The weight of an object is the force that gravity is having over it, and we measure it in Neutowns (N), which equals Kg x m/s².

To find the weight of an object, we use the formula F= m x g.

F stands for force, m for the object's mass, and g for gravity, which is the force that attracts objects to Earth, and we measure it by the acceleration that an object has during free falling.

The Earth's gravity is 9.8 m/s²

1. We use the formula F=m x g

F= 30kg x 9.8 m/s²

F= 294 N

2. We have to convert the 30000g into kg to use the formula

30000÷1000= 30kg

30000g equals to 30Kg, so the object's mass (m) is 30Kg.

F= m X g

F= 30kg X 9.8 m/s²

F= 294 N

3. F= m X g

F= 2kg X 9.8 m/s²

F= 19.6 N

4.We have to convert the 2000g into Kg.

2000÷1000= 2Kg

The object's mass (m) is 2Kg.

F= m X g

F= 2kg X 9.8 m/s²

F= 19.6 N

5. F= m X g

F= 0.5 kg X 9.8 m/s²

F= 4.9 N

6.We have to convert 500g to Kg.

500g÷1000=0.5Kg

The object's mass (m) is 0.5 kg

F= m X g

F= 0.5 Kg X 9.8 m/s²

F= 4.9 N

7. The gravity on the moon is different from the one on Earth. In the formula, instead of 9.8 m/s² for the gravity (g), we use 1.6 m/s².

F= m X g

F= 50Kg X 1.6m/s²

F= 80N

8. The gravity (g) on Mars is 3.7 m/s², so we have to use it in the formula where it says g to find the object's weight on Mars

F= 50Kg X 3.7m/s²

F= 185 N

In humans, brown eyes are dominant to blue eyes. If a blue-eyed man has children with a brown-eyed woman whose mother has blue e

nlexa [21]

Answer:

50%

Explanation:

This question involves a gene coding for eye color in humans. The allele for brown eyes (B) are dominant to blue eyes (b). This means that blue-eyed individual will possess genotype: bb.

According to this question, a blue-eyed man (bb) has children with a brown-eyed woman (B_) whose mother has blue eyes (bb). Since the mother of the brown-eyed woman has a blue eye, this means that the woman will be heterozygous for brown eye (Bb).

Hence, the parents in this question will cross as follows: blue eyed man (bb) × brown-eyed woman (Bb). The offspring/children will have the following genotypes (see attached punnet square); Bb, Bb, bb, bb.

Based on the question, 2/4 = 1/2 of the children will be heterozygous for the eye color trait. That is, ½ × 100 = 50%.
