Can you hit a piece of tissue in mid air with the same amount of force that you can hit a heavy bag? A boxer can hit a heavy bag with great force. Why can’t he hit a piece of tissue paper in midair with the same amount of force? The boxer can only hit […]
Is it possible to have no water in the air?
Is it possible to have no water in the air? There will always be some water vapor in the air unless there is no free water on the surface of the planet. We have air with 0.000% water vapor. Living creatures exhale and plants photosynthesize while this is going on. These actions, not surprisingly, place […]
What is the relationship between valence electrons and ionic charge?
What is the relationship between valence electrons and ionic charge? When forming ions, elements typically gain or lose the minimum number of electrons necessary to achieve a full octet. For example, fluorine has seven valence electrons, so it is most likely to gain one electron to form an ion with a 1- charge. What happens […]

What cells are responsible for bone remodeling?
What cells are responsible for bone remodeling? Bone remodelling relies on the correct function of two principal cells of the bone tissue: the osteoclasts, multinucleated cells that destroy the bone matrix, and the osteoblasts, having osteogenic functions. How is excess calcium removed from the body? The body controls the amount of calcium in the bloodstream […]
What is the function of torque converter?
What is the function of torque converter? A torque converter is a type of fluid coupling which transfers rotating power from a prime mover, like an internal combustion engine, to a rotating driven load. In a vehicle with an automatic transmission, the torque converter connects the power source to the load. What happens when the […]
What are physical fitness tests?
What are physical fitness tests? A physical fitness test may include a repetition maximum of strength-based exercises, like squats or bench presses, to assess muscular strength. It may also involve performing exercises, like bodyweight squats, until exhaustion, which tests muscular endurance. What are the 7 components of skill related fitness? There are six skill-related fitness […]

Is free proton a stable particle?
Is free proton a stable particle? The free proton (a proton not bound to nucleons or electrons) is a stable particle that has not been observed to break down spontaneously to other particles. Which is more stable proton or neutron? Nuclides containing even numbers of both protons and neutrons are most stable and this means […]
What is a Nonconducted P wave?
What is a Nonconducted P wave? A nonconducted PAC results when an ectopic atrial focus occurs so early that it finds the AV node refractory and the impulse is not conducted to the ventricles. This results in a premature, abnormal P wave not accompanied by a QRS complex, but followed by a pause. What does […]
