What is the relationship between muscle length and muscle tension? In its most basic form, the length-tension relationship states that isometric tension generation in skeletal muscle is a function of the magnitude of overlap between actin and myosin filaments. The force generated by a muscle is a function of its velocity. What are the three […]
What are some good aerobic exercises?

Cycling is another type of aerobic exercise with wide appeal and value. Ski Machines, Stair Climbers, Steppers, Ellipticals. Swimming Activities. Jogging, Aerobic Dance. Is Step Aerobics good for belly fat? Step aerobics burns a […]
What is the charging time of capacitor?
What is the charging time of capacitor? The time required for the capacitor to be fully charge is equivalent to about 5 time constants or 5T. Thus, the transient response or a series RC circuit is equivalent to 5 time constants. How do you know how long a capacitor is charged? To calculate the time […]
At what elevation does it get harder to breathe?
At what elevation does it get harder to breathe? Oxygen levels are highest at sea level, but they fall steadily at increasing altitudes. Most men won’t notice any effect until about 5,000 feet; even at one mile above sea level, breathing is comfortable at rest but becomes labored with exertion. Can you breathe 30000 feet? […]
Will entropy ever stop increasing?
Will entropy ever stop increasing? Entropy is the loss of energy available to do work. Another form of the second law of thermodynamics states that the total entropy of a system either increases or remains constant; it never decreases. Entropy is zero in a reversible process; it increases in an irreversible process. Why is entropy […]
What is a soft shadow?
What is a soft shadow? Figure 3.20 Hard-edged shadows indicate light from a small point source. In many cases, using soft shadows (which are less distinct and fade off toward the edges, as in Figure 3.21) for some of your lights tends to look more realistic than using only hard shadows. How do shadows change […]
Is gold a main group element?
Is gold a main group element? Examples of main group elements include helium, lithium, boron, carbon, nitrogen, oxygen, fluorine, and neon. Elements that are not main group elements are the transition metals (such as titanium, copper, and gold), the lanthanides (such as lanthanum and erbium), and the actinides (such as actinium and plutonium). What are […]
What kind of energy is involved when ice melts?
What kind of energy is involved when ice melts? kinetic energy What happens to potential energy while the water is melting? When ice or any other solid melts, its potential energy increases. Indeed, this is the only increase in energy, since the thermal kinetic energy, or temperature, does not increase while melting. At each phase […]

Why is C 14 not used to date dinosaur bones?
Why is C 14 not used to date dinosaur bones? But carbon-14 dating won’t work on dinosaur bones. The half-life of carbon-14 is only 5,730 years, so carbon-14 dating is only effective on samples that are less than 50,000 years old. To determine the ages of these specimens, scientists need an isotope with a very […]
