Which of the following activities belongs on the top of the physical activity pyramid? a. playing video games b. calisthenics c. sprinting d. running

A. playing video games

A physical activity pyramid refers to the visual representation of daily physical activity. It demonstrate, how to increase the physical activity until it becomes daily practice. It's main purpose is to increase the daily physical activity to lead a healthy life. This shows the plan followed by an individual from a period of limit physical activity to the period of heavy exercise, acquired by a person in a daily routine. Therefore, the peak or the top of the physical activity pyramid shows limited or no physical activity and the base will show excess physical activity, which has become a part of daily routine.

Playing video games is the activity which belongs to the top of the physical activity pyramid because in this activity very less amount of work is required to be done by the body muscles, demonstrating very low physical activity.

A. Playing video games

Explanation:

Physical activity pyramid is a visual representation of the activities that one should perform and inculcate in their life to be healthy and fit. It shows what kind of activities should be done and what should be their frequency.

Playing video game will be on the top of the pyramid among the things that one should cut down on and should not play very often.  While moderate exercises like walking, jogging is at the bottom of the pyramid and should be done everyday.

given data:

determine the horse power (h.p) = ?

force applied to move the box(f) = 10 pounds,

box lifted from a distance         (d) = 3 feet

time taken to lift                         (t) = 10 sec,

the horse power is defined as amount of work required to move a load. the horse power is equal to 550 foot-pound per second

                  1 h.p   = 550 foot-pound/second

it can also be defined as the the load that need to be move a body for certain distance in a certain amount of time.

mathematically,

                      h.p = (force × distance)/ time

                            = (10 × 3)/ 10

                            = 30/10

                            = 3 foot -pound/sec

hence, the horse power is needed to move the box is 3 foot-pound/second

important note: 1 h.p = 550 foot-pound/second = 746 watts

the total distance traveled by the car is

30km + 49km = 79 km .
