The three strata of study within the study of kinesiology are:
1. Core scientific domain: the core scientific domain deals with the sub disciplines that are found in kinesiology. Examples of these sub disciplines are biomechanics, sport medicine, exercise physiology, history of sport and dance, neurophysiology of performance, physiology of sport, sociology of sport, etc.
2. Sociocultural based form of movement: this aspect of kinesiology deals with the different types of games, sport and dance that are practised in different cultures and countries. The aspect studies expert skills that are involved in different sociocultural based movements. Examples of sociocultural based movements are aquatics, combative, individual sport, running, etc.
3. Methods in professional application: these deals with the professional training and careers that are available in kinesiology. There are generally five areas of professional training, they are: capacity building, management and administration, performance enhancement, instruction in physical education and research.
Answer:
the required revolution per hour is 28.6849
Explanation:
Given the data in the question;
we know that the expression for the linear acceleration in terms of angular velocity is;
= rω²
ω² = / r
ω = √( / r )
where r is the radius of the cylinder
ω is the angular velocity
given that; the centripetal acceleration equal to the acceleration of gravity a = g = 9.8 m/s²
so, given that, diameter = 4.86 miles = 4.86 × 1609 = 7819.74 m
Radius r = Diameter / 2 = 7819.74 m / 2 = 3909.87 m
so we substitute
ω = √( 9.8 m/s² / 3909.87 m )
ω = √0.002506477 s²
ω = 0.0500647 ≈ 0.05 rad/s
we know that; 1 rad/s = 9.5493 revolution per minute
ω = 0.05 × 9.5493 RPM
ω = 0.478082 RPM
1 rpm = 60 rph
so
ω = 0.478082 × 60
ω = 28.6849 revolutions per hour
Therefore, the required revolution per hour is 28.6849
Linear expansivity, area expansivity and volume or cubic expansivity are
Answer:
He also formulated his law of Universal Gravitation in the Principia, which states that every point mass attracts every single other point mass by a force pointing along the line intersecting both point.
