Answers

Answer 1

Answer:

Answer: find the answer in the explanation

Explanation:

When a magnet is placed at the centre of the paper, and the nails are sprinkled on the paper, what will happen to the nails is that, the nails will form a pattern on the paper according to the magnetic field of the bar magnetic pole.

Other phenomena you can observe are:

1.) The nails will align themselves and show some lines of forces which is equivalent to the magnetic field lines

2.) The direction of the line of forces

3.) The strength of the magnetic field pole.

If you rub your hands together, does the entropy of the universe increas, decrease, or stay the same

Answers

Answer:

When you rub your hands together, the entropy of the universe increases. This increase in entropy is a result of the second law of thermodynamics, which states that in any energy transfer or transformation, the total entropy of an isolated system will always increase over time.

In this case, when you rub your hands together, you are converting some of the ordered kinetic energy of your hand motion into thermal energy (heat) due to friction. This process increases the randomness and disorder of the particles involved, including the molecules in your skin and the surrounding air. As a result, the overall entropy of the system, which includes your hands, the air, and everything else involved, increases.

So, the act of rubbing your hands together leads to an increase in entropy in the universe, consistent with the second law of thermodynamics.

Teen years only
Middle age only
Later years in life

Answers

Answer;

Throughout life

Explanation;

-Muscle strength is the ability to exert a maximal amount of force for a short period of time. In the gym, that may be bench pressing a heavy barbell 5-8 repetitions. The benefits of muscular strength and muscular endurance training include: Reduces body fat and increases lean body mass (muscle mass) Helps to keep bones dense and strong.

-Muscular strength and endurance are important for many reasons: Increases the ability to do activities like opening doors, lifting boxes or chopping wood without getting tired. Reduce the risk of injury.

Thorought life but mostly Through you Teen life because thats when your body start being more active and you should work on your muscle to make sure you have the requirement for your buddy to work properly.
