Falls from a height, being struck by a moving vehicle and being struck by a moving, including flying or falling object, continue as the three main causes of fatal injury, between them accounting for over […]

What does the law of inertia state?

What does the law of inertia state? Law of inertia, also called Newton’s first law, postulate in physics that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon […]

How do you calculate retarding force?

How do you calculate retarding force? 1. Find the accelerating and retarding (stopping) force: Accelerating force: First, find acceleration: 50 km/h is equal to 13.89 m/s (we calculated this with the speed converter). Retarding force: a = (0 – 13.89 m/s) / 8 s = -1.74 m/s2 Fr = 50 kg * -1.74 m/s2 = […]

Does velocity increase with mass?

Does velocity increase with mass? The mass of an object does not change with speed; it changes only if we cut off or add a piece to the object. Can momentum be lost? That is, the momentum lost by object 1 is equal to the momentum gained by object 2. In most collisions between two […]

How do you zero a triple beam balance?

How do you zero a triple beam balance? The triple beam balance is used to measure masses very precisely; the reading error is 0.05 gram. With the pan empty, move the three sliders on the three beams to their leftmost positions, so that the balance reads zero. What is the uncertainty of the triple beam […]

Can I use passport card instead of real ID?

Can I use passport card instead of real ID? Within the United States. Under the REAL ID Act, the passport card is accepted for federal purposes (such as domestic air travel or entering federal buildings), which may make it an attractive option for people whose driver’s licenses and ID cards are not REAL ID-compliant when […]

What is tissue and function?

What is tissue and function? Tissue is a group of cells that have similar structure and that function together as a unit. Primary types of body tissues include epithelial, connective, muscular, and nervous tissues. Epithelial tissues form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in […]

Which of the following is evidence of plate tectonics?

Which of the following is evidence of plate tectonics? Material in the mantle is constantly circulating as a result of heat within the mantle. As the partially molten rock flows, the tectonic plates move as well. Other evidence of plate tectonics include Seafloor spreading, which involves the creation of new crust at divergent plate boundaries. […]
