What is an example of a force multiplier? Some examples of force multipliers are inclined planes and most levers. Some examples are wheels and axles and third class levers. Simple and complex machines. Machines can be either simple or complex. In which condition machine acts as a force multiplier II speed multiplier? Answer. Answer: a) […]
What are the three main characteristics of matter?
What are the three main characteristics of matter? Three States of Matter Matter can exist in one of three main states: solid, liquid, or gas. Solid matter is composed of tightly packed particles. Liquid matter is made of more loosely packed particles. Gaseous matter is composed of particles packed so loosely that it has neither […]
Can fossils be found in granite?
Can fossils be found in granite? Most scientists will say it is very unlikely for fossils of any kind of be found in granite because granite forms at great depths, under conditions that would obliterate organic tissue. It is possible for the native sedimentary rock possessing fossils to be introduced to magma. What environments are […]
Is EMF sensitivity a real thing?
Is EMF sensitivity a real thing? Electromagnetic hypersensitivity (EHS) is a claimed sensitivity to electromagnetic fields, to which negative symptoms are attributed. EHS has no scientific basis and is not a recognised medical diagnosis. Does electromagnetic waves effect on human body? The main effect of radiofrequency electromagnetic fields is heating of body tissues. Despite extensive […]
What happens if I never stretch?
What happens if I never stretch? Stretching keeps the muscles flexible, strong, and healthy, and we need that flexibility to maintain a range of motion in the joints. Without it, the muscles shorten and become tight. Then, when you call on the muscles for activity, they are weak and unable to extend all the way. […]
Which of the following is not considered a region of the spinal cord?
Which of the following is not considered a region of the spinal cord? The d. pelvic region is not considered a region of the spinal cord. Which cells form myelin in the spinal cord? Schwann cells make myelin in the peripheral nervous system (PNS: nerves) and oligodendrocytes in the central nervous system (CNS: brain and […]
What are the three main types of telescopes?
What are the three main types of telescopes? Types of Telescope. There are three main types of telescope. These are refracting telescopes, Newtonian telescopes and Schmidt-Cassegrain telescopes. Why do we use different types of telescope? Most objects give off several frequencies of energy simultaneously. Your body, for instance, glows in thermal infrared down to radio. […]
What is the basic unit of all matter on earth?
What is the basic unit of all matter on earth? Atoms are the basic units of matter and the defining structure of elements. The term “atom” comes from the Greek word for indivisible, because it was once thought that atoms were the smallest things in the universe and could not be divided. What is the […]
What forces are responsible for the movement of ocean water in currents What forces and factors influence the direction and nature of ocean currents?
What forces are responsible for the movement of ocean water in currents What forces and factors influence the direction and nature of ocean currents? Primary forces are thermal expansion and contraction of water, the stress of wind blowing over the water, and density differences between water layers. Secondary forces and factors are the Coriolis Effect, […]
Why do superconductors float?
Why do superconductors float? At normal temperatures, magnetic fields can pass through the material normally. When a magnet is placed above a superconductor at critical temperature, the superconductor pushes away its field by acting like a magnet with the same pole causing the magnet to repel, that is, “float”—no magical sleight of hand required. Can […]
