How do you find displacement with time and distance? Displacement can be calculated by measuring the final distance away from a point, and then subtracting the initial distance. Displacement is key when determining velocity (which is also a vector). Velocity = displacement/time whereas speed is distance/time. What is the formula to find displacement? Displacement (s) […]
What is the angle of incidence in aviation?
What is the angle of incidence in aviation? On fixed-wing aircraft, the angle of incidence (sometimes referred to as the mounting angle or setting angle) is the angle between the chord line of the wing where the wing is mounted to the fuselage, and a reference axis along the fuselage (often the direction of minimum […]
What weighs approximately 1 Newton?
What weighs approximately 1 Newton? In general terms anything that has a mass of 102 grams is said to have a weight of one Newton, because a 0.102 kg object accelerating at 9.81 m/s2 gives you a force of one Newton. Local grocery stores have many things that weigh one Newton. In the fruit department, […]
What is malleability and example?
What is malleability and example? It is the ability of a solid to bend or be hammered into other shapes without breaking. Examples of malleable metals are gold, iron, aluminum, copper, silver, and lead. Gold and silver are highly malleable. The property is not seen in non-metals. What do you mean by ductility class 8? […]
What is a good amount of kJ to burn a day?
What is a good amount of kJ to burn a day? In order to achieve weight loss an individual needs to consume less energy (kilojoules) than the will body burn. For example if an individual needs 8,700 kilojoules per day to maintain weight, reducing daily intake to 6,600 kilojoules (assuming exercise stays the same), should […]
What do you call a female caribou?
What do you call a female caribou? Herds of female caribou, called cows, leave several weeks before the males, which follow with yearling calves from the previous birthing season. What do caribou get eaten by? Foxes, ravens, owls,haegars and hawks are other carrion eaters or scavengers that feed on caribou kills. Native peoples have relied […]
What are the 3 aspects of sound?
What are the 3 aspects of sound? Sound waves are changes in pressure generated by vibrating molecules. The physical characteristics of sound waves influence the three psychological features of sound: loudness, pitch, and timbre. Loudness depends on the amplitude,or height, of sound waves. The greater the amplitude, the louder the sound perceived. What is the […]
Does odometer measure speed or velocity?
Does odometer measure speed or velocity? The odometer gives us only the measure but doesn’t show the direction of velocity. The odometer measures the scalar quantity – the speed of the car. The device may be electronic or mechanical or a combination of the two. How do you calculate distance traveled using odometer? The formula […]
How do you find the slope of a velocity time graph?
How do you find the slope of a velocity time graph? Using the Slope Equation Pick two points on the line and determine their coordinates. Determine the difference in y-coordinates for these two points (rise). Determine the difference in x-coordinates for these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates […]
What is special about pea plants in genetics?
What is special about pea plants in genetics? To study genetics, Mendel chose to work with pea plants because they have easily identifiable traits (Figure below). As a result, one plant’s sex cells combine with another plant’s sex cells. This is called a “cross.” These crosses produce offspring (or “children”), just like when male and […]
