Answer:</h2>
The principle is <u>4) Archimedes' principle</u>.
<h2>
Explanation:</h2>
Archimedes principle, found by the old Greek mathematician and creator Archimedes, expressing that any object totally or incompletely submerged in a liquid (gas or fluid) very still is followed up on by an upward, power the size of which is equivalent to the heaviness of the liquid dislodged by the body.
The volume of dislodged liquid is identical to the volume of an item completely drenched in a liquid or to that portion of the volume underneath the surface for an article halfway submerged in a fluid. The heaviness of the uprooted bit of the liquid is comparable to the extent of the buoyant force.
Answer:
A. OSHA
Explanation:
While OSHA creates and enforces regulations, NIOSH focuses its attention on pushing the scientific field of occupational safety forward. They share the results of their research through robust education programs. They even provide workplace training to improve safety at businesses.
All the energy we need for life comes from the foods we eat and the fluids we drink. These nutrients are broadly broken into fats, proteins, and carbohydrates. Carbohydrates play an especially important role as they provide the quick energy needed for exercise. Carbohydrates found in foods like grains, fruits, vegetables, beans, and dairy products are your body's favorite source of energy, but this is not the only role that carbs play. They also ensure mental sharpness and aid in the metabolism of fat for energy. Complex carbohydrates are an efficient source of energy that fuels muscle contractions. Once eaten, carbs are broken down into smaller sugars (glucose, fructose, and galactose) to be used as energy for immediate tasks. Any unused glucose will be converted into glycogen and stored in the muscles and liver for future use. Glycogen is the energy source most often used for short, intense bouts of exercise such as sprinting or weightlifting. Because glycogen is stored in muscles, it is immediately accessible. During bursts of activity, the stored glycogen will be converted back to glucose and burned for fuel. This is the typical energy source for the first few minutes of any sport.
