Do charges move quickly through empty wires? It’s a common misconception that charges slow down as they go through the filament of a bulb because the filament is thinner than the wires in the rest of the circuit. Animation showing that the current is the same even if the wires have different thicknesses because the […]

Is a higher G value better? Generally, a higher g-value will be beneficial in cooler climates and a lower g-value in warmer climates. Typically g-values will range between 0.2 and 0.7, with solar control glazing having a g-value of less than 0.5. What is a good U value? The best insulating materials have a U-value […]

How long does a jet pack last? about 10 minutes How much would a JetPack cost? Both companies will sell approved clients their own jet pack for between $350,000 and $450,000. Flying strapped to a jet pack is even legal in most countries. Well, not il-legal. Yet. Can I buy a jetpack? Jetpacks in the […]

What are four ways to make an electromagnet stronger? You can make an electromagnet stronger by doing these things: wrapping the coil around a piece of iron (such as an iron nail) adding more turns to the coil. increasing the current flowing through the coil. Is a magnet A solenoid? A solenoid is a cylindrical […]

What are the signs of a bad throttle body? When a throttle body is not functioning correctly, some noticeable characteristics may be poor or very low idle. This can include stalling when coming to a stop or very low idle after starting, or even stalling if the throttle is quickly pressed (resulting in the throttle […]

Is 0 a rational number? Yes, 0 is a rational number. Since we know, a rational number can be expressed as p/q, where p and q are integers and q is not equal to zero. Thus, we can express 0 as p/q, where p is equal to zero and q is an integer. Is negative […]

Which equation should be used for a bomb calorimeter? Constant-Pressure Calorimetry In contrast, a bomb calorimeter ‘s volume is constant, so there is no pressure-volume work and the heat measured relates to the change in internal energy (ΔU=qV Δ U = q V ). Does a bomb calorimeter measure delta H directly? The combustible gas […]

What is the operational definition of love? 1) Love – To care, to support and guide others. 2) Population – the human reproduction. What is the operational definition of shyness? Shyness is the tendency to feel awkward, worried or tense during social encounters, especially with unfamiliar people. Some people’s shyness is so intense, however, that […]

What is the first step to determining your following distance? As you will remember, you measure your following distance by locating a vehicle ahead of you, find a fixed object that the vehicle is passing and count. As you reach the same fixed object, that tells you how many seconds have passed. If you are […]

What is the principle of calorimetry? The principle of calorimetry indicates the law of conservation energy, i.e. the total heat lost by the hot body is equal to the total heat gained by the cold body. What is the calorimetry method? Calorimetry method Measure a volume of an acid and place into a polystyrene cup […]
