Answer:
Packaged foods ( e.g. muffins, cookies or candies ) are not considered as a potentially hazardous food .
Explanation:
A potentially hazardous food is that food ( natural or man made ) which supports the rapid and progressive growth of infectious and toxin - producing microorganism. These foods are typically foods having high protein content or carbohydrate content , have high moisture content or low acidity . Examples of potentially hazardous food includes meats, eggs , cooked beans or peas ,cut fruits and vegetables , cooked vegetables, cooked rice , raw seeds and sprouts , etc. So , packaged foods are not considered as hazardous as they are packaged and so are protected from microbes as they are not in contact of atmosphere . All the other foodstuff , even boiled food is also hazardous as they provide necessary conditions required by microbes to grow like moisture, etc.
Answer:
Explanation:
Formula from the Universal Law of Gravitation :
![F = G\frac{m_1m_2}{r^{2} }](https://tex.z-dn.net/?f=F%20%3D%20G%5Cfrac%7Bm_1m_2%7D%7Br%5E%7B2%7D%20%7D)
5.5 × 10⁸ kg
Given :
F = <u>2 × 10³ N</u>
m₁ = m₂ = <u>M</u>
r = <u>100 m</u>
<u />
Solving :
F = G(M)(M) / r²
M² = Fr²/G
M = √2 × 10³ × (10²)² / (20/3) × 10⁻¹¹
M = √10¹⁸ × 6 / 20
M = 10⁹ √0.3
M = 10⁹ × 0.55
M = 5.5 × 10⁸ kg
