auditory
circulatory
respiratory
integumentary
muscular
reproductive

Answers

Answer 1
Answer:

Answer: circulatory

respiratory

muscular

Explanation:

The physical fitness can be define as the state of well being and health. It indicates towards the ability of the organisms to perform various aspects of physical activities such as sports, daily routine work, and occupational tasks. It is achieved by moderate to vigorous physical exercises, sufficient amount of rests and proper nutrition.

The physical fitness involves the proper functioning of the vital systems of the body these includes the respiratory, circulatory and muscular. As the body performs exercise it requires more amount of oxygen also the muscles performing activity deprive of the oxygen, the rate of respiration increases, more amount of blood is pumped out by the heart to fulfill the need of oxygen.

Answer 2
Answer: Respiratory
Circulatory
Muscular

Which of these follows from Newton's laws about the energy of a moving object? A)The total mechanical energy of an object is always constant. B)The kinetic energy of an object remains the same if friction is absent. C)The mechanical energy remains the same if there are only conservative forces acting. D)The total of all forms of energy is always constant.

Answers

The correct answer for the question that is being presented above is this one: "C)The mechanical energy remains the same if there are only conservative forces acting." The statement that shows that Newton's laws about the energy of a moving object is that the mechanical energy remains the same if there are only conservative forces acting.

A water skier has a mass of 79.0 kg and accelerates at 1.40 m/s2. What is the net force acting on him? F = ___ NAnswer choices
56.4
111
77.6
0.018
80.4
774.2

Answers

The answer is 111.

Using Newton's Second Law, F=ma, plugging known values in we get:

F = (79kg)(1.4m/s^2) = 110.6N ≈ 111N

Final answer:

The net force acting on the water skier, calculated using Newton's second law (F=ma), is approximately 111 Newtons.

Explanation:

The net force acting on the water skier can be calculated using Newton's second law, which states that force equals mass times acceleration (F=ma). In this instance, the skier's mass (m) is 79.0 kg and his acceleration (a) is 1.40 m/s2.

By multiplying these values together (F = 79.0 kg * 1.40 m/s2), we find that the net force acting on him is 110.6 Newtons (N). However, this exact value is not listed in the answer choices. Among the given choices, 111 N would be the closest approximation to the calculated value.

What is the difference between the deviation and refraction? ​

Answers

Answer:

Refraction is the change in direction of waves that occurs when waves travel from one medium to another. Refraction is always accompanied by a wavelength and speed change. Diffraction is the bending of waves around obstacles and openings.
