what is the minimum force you have to pull with to move the box that is on the ice?

Answers

So to directly answer your question, any amount of force greater than zero in a particular direction will move an object. By Newton's second law f=ma force is the product of mass and acceleration, solving for acceleration a=f/m so any amount of force causes an acceleration.

Any force acting in that direction that is larger than zero will cause an object to move.

What is force?

Force is defined as a push or pull that an object experiences as a result of interacting with another object. Each object is subject to a force whenever two objects interact. A body at rest can be forced to move. It can either slow down or stop a moving body. It can quicken the pace of a moving object. It can change a moving body's size, form, and direction in addition to those three.

According to Newton's second law, which states that force is the product of mass and acceleration (f=ma), any amount of force will result in an acceleration (a=f/m). By dividing the normal force by the coefficient of friction, the friction force is calculated. Motion is constantly opposed by the frictional force

Thus, an object will move with any force greater than zero acting in that direction.

and exhibits the following symptoms: weight loss, low-grade fever, night
sweats, and vulnerability to pneumonia and intestinal disorders. What
bloodborne disease might this employee have?
Select the best option.

Hepatitis B
Hepatitis C
HIV

Answers

Answer:

According to the symptoms presented, the blood-borne disease that the employee exposed to potentially infectious bodily fluid could have is HIV.

Explanation:

HIV infection is a disease that can be transmitted by contact with blood or body fluids of a sick person, being a biological risk for health personnel.

Acquired immunodeficiency syndrome is the result of HIV infection.This virus produces a state of immunosuppression that leads to symptoms such as weight loss, low-grade fever, night sweats, increased susceptibility to infections such as pneumonia, and digestive disorders such as chronic diarrhea.

Depending on the symptoms, the employee may have acquired HIV infection.

The other options are not correct because:

    Acute hepatitis B or C virus infections cause abdominal pain, high fever and acute weight loss, but do not increase susceptibility to pneumonia or gastrointestinal disorders.

A healthcare worker who has been exposed to potentially infectious bodily fluid and exhibits the symptoms above described might have HIV.

Human immunodeficiency virus (HIV) is a virus that causes damages to the immune system, leading to a disease called acquired immunodeficiency syndrome (AIDS).

Some common symptoms of AIDS include fever, chills, night sweats, muscle aches, fatigue, etc.

HIV can be transmitted through blood or other fluids of the body, only when viral load is high.

It has been estimated that healthcare professionals who are exposed to potentially infectious HIV fluids may have a 0.23% risk of becoming infected.

In conclusion, a healthcare worker who has been exposed to potentially infectious bodily fluid and exhibits the symptoms above described might have HIV.
