What is a muscle moment arm? The moment arm of a muscle force is defined by the perpendicular distance between the muscle’s line of action and the instantaneous centre of rotation of the joint in which it spans, and represents the capacity of that muscle to exert a joint torque (Pandy, 1999). Does a longer […]
Which installation is not covered by the NEC?
Which installation is not covered by the NEC? The NEC does not cover electrical installations in ships, water- craft, railway rolling stock, aircraft, or automotive vehicles. What is the purpose of the NEC? The NEC (the National Fire Protection Association’s NFPA 70) is a widely-adopted model code for the installation of electrical components and systems. […]

Why do we use resistors?
Why do we use resistors? A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses. What causes resistors to burn? Blowing Up a […]
What are 3 examples of invasive species?
What are 3 examples of invasive species? Notable examples of invasive plant species include the kudzu vine, Andean pampas grass, English ivy, Japanese knotweed, and yellow starthistle. Animal examples include the New Zealand mud snail, feral pig, European rabbit, grey squirrel, domestic cat, carp, and ferret. What are two human activities that could contribute to […]
What will happen if the chloroplast stops working?
What will happen if the chloroplast stops working? because chloroplasts have chlorophyll, which absorbs energy from the sun. This energy is used for photosynthesis. it also can affect the whole process of photosynthesis the green plant will not be able to carry out the process of photosynthesis which means the plant will die. What will […]
How many H+ are pumped into the intermembrane space?
How many H+ are pumped into the intermembrane space? During the reduction of oxygen, two H+ ions are extracted from the matrix and transferred to the reduced oxygen atom, thus forming water (H2O). Simultaneously, the complex pumps 4 H+ ions into the intermembrane space. Is Complex 2 a proton pump? Complex II does not pump […]
What are 2 disadvantages of wind energy?
What are 2 disadvantages of wind energy? The two major disadvantages of wind power include initial cost and technology immaturity. Firstly, constructing turbines and wind facilities is extremely expensive. The second disadvantage is technology immaturity. Why is wind energy bad? Wind turbines are a potential threat to wildlife such as birds and bats. Deforestation to […]
What is the best wattage microwave to buy?
What is the best wattage microwave to buy? A 1,000-watt or 1,200-watt option is the best for most people’s needs, however. It’s enough power to heat or defrost anything from the freezer section thoroughly. Cheaper microwaves with under 700-watts take longer to cook your food efficiently and may struggle to heat things evenly. How do […]
What do all the physical properties of minerals result from?
What do all the physical properties of minerals result from? The physical properties of minerals are related to their chemical composition and bonding. Some characteristics, such as a mineral’s hardness, are more useful for mineral identification. Color is readily observable and certainly obvious, but it is usually less reliable than other physical properties. What are […]
