Answer: Option (b) is the correct answer.
Explanation:
Density means the degree of compactness, that is, when particles of an object or substance are closer to each other then it is said that density of object is high.
Therefore, when ocean water gets colder then particles of water will gain potential energy and thus they will come closer to each other. Hence, there will be increase in density of ocean water when it gets colder.
Answer:
a= -0.86 m/s²
The negative sign shows that ball down the ground or moving down
Explanation:
Vf² - Vo² = 2gS
where
Vf = velocity of clay as it hits the ground
Vo = initial velocity of clay = 0
g = acceleration due to gravity = 9.8 m/sec^2 (constant)
S = distance travelled by clay = 15 m
Substituting appropriate values,
Vf² - 0 = 2(9.8)(15)
Vf = 17.15 m/sec.
Formula to use is,
V - Vf = aT
where
V = velocity of clay when it stops = 0
Vf = 17.15 m/sec (as determined above)
a = acceleration
T = 20 ms
Put the values to find acceleration
a=(V-Vf)/T
a=(0-17.15)/20
a= -0.86 m/s²
The negative sign shows that ball down the ground
B. Improved strength across the entire range of motion
C. Improved joint flexibility
D. Motivational
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.
The primary advantage of isometric exercise is rapid strength improvement in a specific area, not necessarily improved flexibility or range of motion.
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.
