Answer:
Independent variable: The diameter of the wooden pins.
Dependent variable: The depth of the pins in the sand.
Control variable: height of 15 cm at which the pins will be thrown, boxes containing 30 kg of sand and weights of 80 grams.
Explanation:
An independent variable is one that does not need the influence of another variable to happen and that, its variation, influences that a measurable result occurs. In this case, as we know that the depth of the wooden pins is measured according to the influence of the diameter of these pins, we can say that the diameter of the wooden pins is the independent variable.
The dependent variable, on the other hand, is one that shows a measurable result through the influence of the independent variable. In this case, we can say that the depth of the wooden pins in the sand is the independent variable.
The control variable, in turn, is the factor that establishes an egalitarian environment in which the research will be established. In this case, the control variable is the height of 15 cm at which the pins will be thrown, the boxes containing 30kg of sand and the weights of 80 grams.
I do hope the main reason why Tommy might use static stretching coincides with common purpose of stretching! And actually static stretching is usually used before workout in order to warm body up, which means tha answer is : <span>to prepare his muscles for sports. Hope it helps!</span>
Answer:
Recruitment; rate coding.
Explanation:
Muscle is one of the important tissue of the body that helps in the movement of the body. Cardiac muscle, smooth muscle and skeletal muscle are three different types of muscle.
The muscle has the ability to change its contraction force depends upon the two factors. The rate coding adjusts the firing of the neural muscle rate while travelling down to the motor neuron via the central nervous system. The motor unit recruitment is the way bu which the number of different units recruited in a particular task can be altered.
Thus, the correct answer is option (c).
