makkiz [27]

Answer:

sexual selection

natural selection

Explanation:

Natural selection is an evolutionary mechanism (changes the allele frequency) by favouring traits that are advantageous among others because they increase the survival and reproduction. In the example above, mosquitofish that live in the predator-rich ponds devoloped a trait that help them survive (swimming in short, fast bursts). This adaptation to environment is favourable by natural selection.

Sexual selection refers to the female mosquitofish and the fact that they choose their males (with better reproductive success).

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 <u>Neutowns (N), which equals Kg x m/s².</u>

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.

<u>The Earth's gravity is 9.8 m/s²</u>

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
