Why do we use FM? Find Your Local Station: With AM radio, the amplitude, or overall strength, of the signal is varied to incorporate the sound information. With FM, the frequency (the number of times each second that the current changes direction) of the carrier signal is varied. FM signals have a great advantage over […]
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 […]
What types of combustion are there?
What types of combustion are there? Here’s a closer look at five types of combustion: Complete Combustion. Complete combustion requires a combination of fuel and oxygen. Incomplete Combustion. Incomplete combustion occurs when there is not enough oxygen for the fuel to fully react. Rapid Combustion. Spontaneous Combustion. Explosive Combustion. What three things are needed for […]
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 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 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 […]
How much does an elephant cost?
How much does an elephant cost? Photo courtesy of The David Sheldrick Wildlife Trust. In their report, iworry estimated the raw-ivory value of a poached elephant to be $21,000. In contrast, a living elephant is worth more than $1.6 million over its lifetime, largely because of its eco-tourism draw. Can I own a baby elephant? […]
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 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 […]
