What else can I help you with?
When muscles contrast do they get shorter or longer?
Do you mean "contract". Well, when muscles contract they get shorter and fatter. When they relax they get longer and thinner.
When muscles contract do they become shorter or longer?
muscles become longer, but thinner
Is a shorter or longer bridge stronger?
Everything else being equal, a shorter bridge is stronger: it will weigh less, and therefore will not have to support so much of its own weight.
What tighten and get shorter when you inhale but relax and get longer when you exhale?
The diaphragm and intercostal muscles tighten and contract during inhalation, causing the rib cage to lift and expand, resulting in a shorter length. During exhalation, these muscles relax, allowing the rib cage to lower and return to its longer length.
Is it true that muscle cells can move a bone when they extend or get longer as well when they contract or get shorter?
No, muscles only do work when contracting. Thus muscles come in opposing sets that pull in opposite directions.
Is shorter or longer straws stronger?
Shorter straws are generally stronger than longer ones due to their reduced length, which minimizes the risk of bending or collapsing under pressure. The structural integrity of a straw is influenced by its height; shorter straws have less leverage against external forces. However, the material and design also play significant roles in determining overall strength.
Are tall people stronger?
Yes. They are naturally stronger than shorter people, unless they are anorexic. On average, tall people are stronger because longer limbs generate more leverage and have a greater range of motion.
What is the effect of cardiovasvular endurance on the muscles?
When you build cardiovascular endurance you increase the ability of your body to absorb oxygen and carry it to the muscles which gives them the ability to perform longer and stronger.
What is the difference between your leg and your stomach muscles?
Leg muscles tend to be longer and less dense or compact than abdominal muscles. Leg muscles are also, of course, found on your legs. Abdominal muscles are shorter and more compact than leg muscles and are found on your torso, below the breasts down to the groin.
Why is the longer leg longer than the shorter leg if the shorter leg is longer than the longer leg?
Because if the shorter leg was shorter than the longer leg was long, then the longer leg wouldn't be longer than the shorter leg is short. The short leg would be the longer one rather than the long one being the short one.
What is meant by the statement Contraction is active but elongation is passive?
It's probably referring to muscles. Muscles do work when they get shorter. Muscles can't "get longer"; instead what happens is that another muscle pulls in the opposite direction and the first just sits there and gets stretched.
Does friction waste more work on longer or shorter planes well how can you tell?
Its longer cuz the longer the flatter the incline plane, and on flatter planes, the object presses more than on the shorter ( steeper ones)
