What happens to the internal energy of a system when work is done on it?
If the internal energy of the system increases the temperature will increase.
Number of times that a machine increases the input force?
Increasing the distance between the load and pivot increases the work output of a machine.
What is increased cardiac output?
Cardiac output is the volume of blood that your heart pumps per minute. With it being increased, it means that there is an increase in volume of blood that your heart pumps around the body. Hope this helps with whatever you're doing - like PE BTEC...
Which is not a way that a machine makes work easier?
Increasing the distance between the load and pivot increases the work output of a machine.
How can you increase the work output of a machine?
the only way to increase the work output is to increase the amount of work you put into the machine.
What is the purpose of antiangina drugs?
By relaxing the blood vessels, antiangina drugs reduce the heart's work load and increase the amount of oxygenrich blood that reaches the heart.
How does a beta blocker help tachycardia?
Reduces the work load and increases cardiac output
Why more fuel is required when load of an electrical generator is increased?
It's all about the conservation of energy, and the fact that you don't get something for nothing! As a generator's load increases, the current through the machine increases, so more work has to be done to overcome the resulting increase in 'motor action' caused by the load current. As work is the conversion of one form of energy into another, then more energy must be supplied -and that energy is provided by the fuel supplied to the prime mover.
What happens to the internal energy of a system when work is done on it?
If the internal energy of the system increases the temperature will increase.
How does exercise effect heartrate?
It increases it and causes the heart to work harder.
Number of times that a machine increases the input force?
Increasing the distance between the load and pivot increases the work output of a machine.
How the heart respond to the strenuous exercise?
when you exercise, the heart rate increases, (as does your breathing pace), so that more oxygen can be carried in the blood to your muscles. The more intense the exercise, the more your muscles have to work, so more oxygen is required and your heart rate will increase. The quicker you heart rate returns to normal, the better your fitness.
Does exersice increase the size of your heart?
No, exercise doesn't increase the size of the heart. Exercise does strengthen the heart so that you can become more active in life.
How does a third class lever work?
With a third class lever, the input force is located between the fulcrum and the load. They increase the distace the load is carried.
What happens to a persons resting heart rate when doing cardiorespratory exercise and conditioning?
It decreases because your heart no longer has to work as hard.
What does a ramp increase?
It increases the distance over which work is performed, while reducing the power required over the period of the work performed.
What happens to your heart rate when you excercise?
Depending on how light or heavy exercise is will depend on the change that occurs. Typically during exercise heart rate will increase. This is in order to increase blood flow to the working muscles to allow for increased respiration - in order for the muscles to work efficiently. Therefore the more strenuous the exercise, the more your heart rate will increase. Blood pressure will also increase during exercise and again depends on intensity levels. During exercise such as running/cycling/swimming systolic pressure will increase progressively whereas diastolic pressure will increase only slightly. During weight lifting exercises, both systolic and diastolic pressures will rise. Obviously these effects will vary from person to person, depending on age, gender, exercise level, exercise intensity etc. etc.
