write any two importance of simple machine​

Answers

Answer 1

Answer:

Simple machines are useful because they reduce effort or extend the ability of people to perform tasks beyond their normal capabilities. Simple machines that are widely used include the wheel and axle, pulley, inclined plane, screw, wedge and lever. There are three ways simple machines make work easier: by increasing the distance through which force is applied, by changing the direction of applied force, or by multiplying force of speed of the energy applied.

Chelsea and Marie are at the Olympics and watching the track and field events. They observe the landing of the shot-put with a big "thud," vaulters clearing the bar for the pole vault, runners starting their 26.2 mile marathon, and racers completing their final lap of the mile run. Analyze the events and determine which pair of events is considered anaerobic activities: Marathon and Pole Vault Marathon and Mile run Pole vault and Shot-put Shot-put and Mile run

Answers

Answer:

The two events that are anaerobic activities are:

Pole vault and Shot-put.

Explanation:

a) Analysis of events:

Events         Type of activity

Marathon    aerobic

Pole Vault   anaerobic

Mile run      aerobic

Shot-put     anaerobic

b) Anaerobic activities like pole vault and shot-put involve quick bursts of energy in the absence of free oxygen. They are usually performed using maximum effort for a short period of time. Other examples include jumping, sprinting, or heavy weight lifting.  The aerobic activities like mile run and marathon do not require quick bursts of energy.  They require sustained efforts for some long time and in the presence of free oxygen.  The athlete's respiration and heart rate differ in aerobic activities versus anaerobic exercises.  During aerobic activities, oxygen remains the main energy source.

Which statement about resting heart rate is true? Increased physical activity and cardiovascular endurance will lower your Resting Heart Rate. Resting heart rate is calculated by subtracting your age from 220. Use your Resting Heart Rate to calculate your Maximal Heart Rate. Your Resting Heart Rate is lowest just before going to bed.

Answers

Answer: (A) or “Increased physical activity and cardiovascular endurance will lower your Resting Heart Rate

This is because as you continue to train your heart, it becomes more effective in delivering blood. Your RHR will drop due to the bigger bursts of blood your heart is pumping out in which case fewer beats or pumps are needed.
This takes some work load off of the heart and is one of the main reasons why this method of exercise is recommended by Heath professionals.

"More exercise and cardiovascular stamina will reduce your resting heart rate." This is due to the fact that as you keep exercising, your heart will grow more proficient at transporting blood.

What is Physical activity?

Our heart is pumping out more blood in larger bursts, your RHR will decrease because fewer beats or pumps are required. This relieves some of the heart's effort, which is one of the key arguments in favor of this form of exercise among health experts.

According to the WHO, physical activity is any skeletal muscle-driven movement that involves the use of energy.

All movement, whether done for recreation, transportation to go to and from locations, or as part of a person's job, is considered physical exercise. Both vigorous and moderate physical activity are beneficial to health.

Therefore , "More exercise and cardiovascular stamina will reduce your resting heart rate." This is due to the fact that as you keep exercising, your heart will grow more proficient at transporting blood.

To be effective, an exercise program must be __________. A. uniquely tailored to every person B. maintained at a constant level of difficulty C. applied generally to whole-body fitness D. constantly increasing in difficulty D. all of the above D. all of the above

Answers

Answer:

To be effective, an exercise program must be uniquely tailored to every person. The correct option is A.

Explanation:

Exercise is defined as a physical activity performed in different ways by an individual to increase physical fitness. An exercise program is being structured according to the specific needs of the individual performing them. This is so to yield an effective result.

While developing an exercise plan, it should be balanced as there is no single type of exercise that can take care of all the needs of an individual. This can be accomplished by creating a balanced routine to meet an immediate need. For example an individual that has the desire to lose some weight, an elderly patient with cardiac condition or a patient recovering from fractured bone. They have different health challenges and for them to achieve an effective result, their exercise program must be tailored according to their needs.
