What is the difference between hold relax and contract relax? 2. Contract-relax. Another common PNF technique is the contract-relax stretch . It is almost identical to hold-relax, except that instead of contracting the muscle without moving, the muscle is contracted while moving. Which type of stretching has the highest risk of injury? Ballistic stretching What […]
What factors are effect on the resistivity?
What factors are effect on the resistivity? Then the factors which affect the resistance (R) of a conductor in ohms can be listed as: The resistivity (ρ) of the material from which the conductor is made. The total length (L) of the conductor. The cross-sectional area (A) of the conductor. The temperature of the conductor. […]
Is current electrons per second?
Is current electrons per second? Electrical current is the flow of charge through a circuit. It is defined as the number of coulombs (1 Coulomb = 6.25 x 1018 electrons) of charge passing a point per second. Electric current has the symbol I and the unit A (Amps). How many electrons per second does an […]
Why are mass and volume extensive properties?
Why are mass and volume extensive properties? Extensive properties, such as mass and volume, depend on the amount of matter being measured. Intensive properties, such as density and color, do not depend on the amount of the substance present. Physical properties can be measured without changing a substance’s chemical identity. What is the difference between […]
What does medium rare steak feel like?
What does medium rare steak feel like? If you’d like your steak medium-rare, it should feel like your cheek: tender and soft but still fleshy (as opposed to raw, which would be just soft). If you want a medium steak, touch your chin: The steak should still be tender, but with some resistance. How do […]
How long does it take to heal after radiation therapy?
How long does it take to heal after radiation therapy? Most side effects generally go away within a few weeks to 2 months of finishing treatment. But some side effects may continue after treatment is over because it takes time for healthy cells to recover from the effects of radiation therapy. Late side effects can […]
Which kind of roller bearing is best for equipment that must run at high speed?
Which kind of roller bearing is best for equipment that must run at high speed? If you need a bearing capable of withstanding a high radial load, then we recommend a cylindrical roller bearing. On the other hand, if your bearing needs to support lighter loads a ball bearing might be sufficient as they are […]
How do you find a variable in an equation?
Why do electrons lose energy?
Why do electrons lose energy? An excited atom is unstable and tends to rearrange itself to return to its lowest energy state. When this happens, the electrons lose some or all of the excess energy by emitting light. Does losing an electron release energy? When electrons are removed from an atom, that process requires energy […]
Can you use a solenoid as a relay?
Can you use a solenoid as a relay? Solenoids are a type of relay engineered to remotely switch a heavier current (typically ranging from 85-200 amps). In contrast to the smaller electromechanical cube relays, a coil is used to generate a magnetic field when electricity is passed through it, which effectively opens or closes the […]
