How do you find the mechanical advantage of a slope? To find the ideal mechanical advantage of an inclined plane, divide the length of the slope by its height. An inclined plane produces a mechanical advantage to decrease the amount of force needed to move an object to a certain height; it also increases the […]
Can an object accelerate with zero velocity?
Can an object accelerate with zero velocity? Yes, an object can have zero velocity and still be accelerating simultaneously. Let us consider an object moving in the forward direction. Now, suddenly a force acts on it and tries to accelerate the object in the reversed direction. Does velocity have direction? The direction of the velocity […]
What is the role of stomata in transport in plants?
What is the role of stomata in transport in plants? Stomata are another very important feature for gaseous exchange and transport in plants. They’re found on the underside of the leaf and basically act like pores allowing carbon dioxide to enter to be used for photosynthesis and allowing oxygen, a waste product of photosynthesis, to […]
What is a super derecho?
What is a super derecho? A derecho (/dəˈreɪtʃoʊ/, from Spanish: derecho [deˈɾetʃo], “straight” as in direction) is a widespread, long-lived, straight-line wind storm that is associated with a fast-moving group of severe thunderstorms known as a mesoscale convective system and potentially rivaling hurricanic and tornadic forces. What is a Derecho Storm 2020? NOAA officially defines […]
What are the 4 Labour codes?
What are the 4 Labour codes? The four broad codes on wages, industrial relations, social security and occupational safety, health & working conditions (OSH) have already been notified after getting the President’s assent. But for implementing these four codes, the rules need to be notified. How many types are there of Labour law? two What […]
What is the difference between field capacity and wilting point?
What is the difference between field capacity and wilting point? At “Field Capacity” (FC) the soil is wet and contains all the water it can hold against gravity. At the “Permanent Wilting Point” (PWP) the soil is dry and the plant can no longer extract any more water. The plant available water is expected to […]
What type of movement is exhibited at the knee joint?
What type of movement is exhibited at the knee joint? The knee joint is a hinge type synovial joint, which mainly allows for flexion and extension (and a small degree of medial and lateral rotation). It is formed by articulations between the patella, femur and tibia. What are the 7 principles of biomechanics? Seven Principles […]
Are GMOs safe?
Are GMOs safe? The U.S. Food and Drug Administration (FDA), U.S. Environmental Protection Agency (EPA), and U.S. Department of Agriculture (USDA) ensure that GMOs are safe for human, plant, and animal health. Is GMO free the same as organic? The use of genetic engineering, or genetically modified organisms (GMOs), is prohibited in organic products. This […]
Where can we see reflections?
Are light wires live when switch is off?
Are light wires live when switch is off? Normally, hot is switched. Neutral and ground are not switched. Normally, that results in a safe environment where this is nothing “live” when hot is switched off. Fixtures wired correctly so that the wires that should be hot are hot and the wires that should be neutral […]
