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 […]
How do you find displacement with time and distance?
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, […]

Is it better to be upstairs or downstairs in an earthquake?
Is it better to be upstairs or downstairs in an earthquake? In an earthquake, the area immediately outside a building is the most dangerous place to be. The taller the building, the wider the danger zone. A basic rule of thumb is if you are inside, stay inside and if you are outside, stay outside. […]
What is U value of insulation?
Why is it difficult for a high speed car to negotiate an unbanked turn?
Why is it difficult for a high speed car to negotiate an unbanked turn? (a) A huge force is pushing the car outward. (b) The magnitude of the friction force might not be enough to provide the necessary radial acceleration. A car negotiating an unbanked road at high speed is actually accelerating as the direction […]
Why is NO2 not a greenhouse gas?
Why is NO2 not a greenhouse gas? Neither nitric oxide nor nitrogen dioxide are greenhouse gases, although they are important in the process of creation of tropospheric ozone which is a greenhouse gas. Because of this, there is general agreement that the atmospheric sources and sinks of nitrous oxide are difficult to bring into balance. […]
