Ethan has been eating salads without first washing the lettuce. He risks ingesting E-Coli and Salmonella bacteria.

  • You could inhale dangerous bacteria from the soil or pesticides used on the produce in the fields if you eat unwashed produce. Furthermore, it's possible that you'll consume bugs that were collected with the produce.
  • Animal-based foods like meat, poultry, eggs, dairy products, and shellfish are frequently the cause of food poisoning in humans.
  • Fruits, vegetables, and other raw foods, however, can potentially be polluted and sicken people if they aren't rinsed beforehand.
  • Fruits and vegetables that are the safest are cooked; those that are the next-safest are washed.
  • Prevent eating unwashed fresh food. Fresh produce has many health benefits, but eating raw fruits and vegetables occasionally puts you at risk for food poisoning from pathogens including Salmonella, E. coli, and Listeria.

Calculate the net force on the Fx and Fy<br> of<br> 20 N<br> 17 N<br> 45.50<br> 250
marysya [2.9K]

Answer:

F_{net} is 26.25 N

Explanation:

Given that: F_{x} = 20 N, F_{y} = 17 N.

This implies that the two forces are acting at right angle to each other. Thus applying the Pythagoras theorem, we have;

F_{net} = \sqrt{F_{x} ^{2} + F_{y} ^{2}  }

       = \sqrt{(20)^{2} + (17)^{2}  }

       = \sqrt{400 + 289}

F_{net} = \sqrt{689}

      = 26.2488

F_{net} = 26.25 N

The net force is 26.25 N.

Jose and Karl were both exposed to the influenza virus at work. Jose had a flu shot made from killed influenza virus six weeks a
ipn [44]

The correct answer is Karl will get sick and Jose will not this time, but neither will get this influenza again since they both will have acquired active immunity to it.

In the case of Jose artificially active immunity has been induced due to vaccination. A vaccine instigates a primary response against the antigen without resulting in any signs of the disease. On the other hand, Karl will acquire active immunity naturally in future, as when an individual get exposed to a live pathogen, he or she develops the disease, and turns immune as an outcome of the primary immune response.
