Which one of the following choices best describes an advantage of isometric exercise? A. Rapid strength improvement
B. Improved strength across the entire range of motion
C. Improved joint flexibility
D. Motivational

Answers

Answer 1

Answer:

Answer: C. Improved joint flexibility

Explanation:

Isometric exercises are the exercises which involves the contraction of particular muscles or group of muscles. In these exercises the muscles do not change their length and the joints does not move. These are the exercises which are done in one position. These exercises are performed in order to obtain strength during training exercises during which the muscle length and joint angles do not basically change. These exercises are high intensity exercises and contributes to the building of muscles and burning of fat.

On the basis of the above information, A. Rapid strength improvement is the correct option.

Answer 2

Answer:

Final answer:

The primary advantage of isometric exercise is rapid strength improvement in a specific area, not necessarily improved flexibility or range of motion.

Explanation:

The best answer that describes an advantage of isometric exercise is A. Rapid strength improvement. Isometric exercises are often used for rehabilitation and building strength, as they involve the contraction of a specific set of muscles in a static position. This type of exercise does not involve the muscle changing length or the joint angle changing, which allows for an increase in strength in a very focused manner.

This does not necessarily mean that isometric exercises enhance joint flexibility (C) or improve strength across the entire range of motion (B) as the movement is static. The motivation aspect (D) can differ from person to person, but it's not a direct physical benefit of isometric exercises.

Imagine that a tank is filled with water. The height of liquid column is 7 meters and the area is 1.5 square meters (m2). What's the force of gravity acting on the column of water?

Answers

-- The volume of water is (1.5 m² x 7 m) = 10.5 m³

   10.5 m³ = 10,500 liters

   Water mass = (10,500 liters) x (1 kg/liter) = 10,500 kg.

-- "Force of gravity on the water"

= Weight of the water = (10,500 kg) x (9.8 m/s²) = 102,900 newtons

-- Pressure on the bottom of the tank =

   (102,900 newtons) / (1.5 m²)

   = 68,600 nt/m² = 68,600 pascal .

your answer is 102,900 N

A baseball bat is a lever. Which of the following explains how a baseball bat differs from a lever like a pry bar?

Answers

Complete question is;

A baseball bat is a lever. Which of the following explains how a baseball bat differs from a lever like a pry bar?

A) In a baseball bat, effort force is smaller and is applied over a large distance, while the resistance force is smaller and is applied over a long distance.

B) In a baseball bat, effort force is smaller and is applied over a large distance, while the resistance force is smaller and is applied over a short distance.

C) In a baseball bat, effort force is larger and is applied over a short distance, while the resistance force is smaller and is applied over a long distance.

D) In a baseball bat, effort force is larger and is applied over a short distance, while the resistance force is smaller and is applied over a short distance.

Answer:

C) In a baseball bat, effort force is larger and is applied over a short distance, while the resistance force is smaller and is applied over a long distance.

Explanation:

The correct answer is option C. This is because unlike in a pry bar, the effort force when swinging a baseball bat is larger and it is applied over a short distance; and in return the resisting force is smaller and it's applied over a long distance.
