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

Artyom0805 [142]

Answer:

Connective Tissues

Explanation:

According to my research on studies conducted by various medical professions, I can say that based on the information provided within the question this scientist is most likely looking at Connective Tissues. These are tissues in which material secreted by the cells is fills up the spaces between the cells, thus connecting or binding otherwise separate tissues or organs. Which is what the scientist seems to be describing.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

How an immune response stars after a macrophage attacks a pathogen
marishachu [46]
After the macrophage fails the Helper T Cell stimulates the B cells (create antibodies) if pathogen is extracellular and Cytotoxic T Cells (killer T cells, release perforin) if pathogen is intracellular. Once the pathogen is killed the B Cells create Memory B Cells and the Killer T Cells create memory T Cells.
