What helps in supporting a ladder inclined to a wall? Answer: Gravity acts on the center of mass of the ladder. What degrees should a ladder be? Set up your ladder at the right angle and in the right location (avoid overreaching). Figure 5 gives guidance in relation to setting up ladders on slightly sloped […]
What are the consequences of not paying debt?
What are the consequences of not paying debt? So here’s what you can expect if you don’t pay your debts: Your debt will go to a collection agency. Debt collectors will contact you. Your credit history and score will be affected. Your debt will probably haunt you for years. You’ll pay off the debt or […]
What is the use of sampling theorem?
What is the use of sampling theorem? The sampling theorem specifies the minimum-sampling rate at which a continuous-time signal needs to be uniformly sampled so that the original signal can be completely recovered or reconstructed by these samples alone. This is usually referred to as Shannon’s sampling theorem in the literature. What is sample theory? […]
Why evaporation is a slow process?
Why evaporation is a slow process? For evaporation, no additional source of heat (such as a burner) is required. Evaporation is the natural process whereas boiling is an artificial process. Thus, evaporation occurs without external heat supply and is a natural process. It is a slow process. Is boiling a form of evaporation? Summing up, […]
What are some losses of mechanical energy?
What are some losses of mechanical energy? The mechanical energy is then transported to the wheels which increases the kinetic energy of the car. Some of this kinetic energy is lost to the sound of the engine, light from combustion, and to heat energy from the friction between the road and the tires. What is […]
Do train tracks stop your car?
Do train tracks stop your car? Cars very rarely get stuck on railroad grade crossings. Railroads work extremely hard to make sure that doesn’t happen. A more typical reason for a stall is the fact that people slow down to cross the grades, and some poorly tuned engines are more likely to stall when going […]
How much charge can be stored in a capacitor?
How much charge can be stored in a capacitor? Capacitors do not store charge. Capacitors actually store an imbalance of charge. If one plate of a capacitor has 1 coulomb of charge stored on it, the other plate will have −1 coulomb, making the total charge (added up across both plates) zero. Do Capacitors store […]
Does Group 17 lose or gain electrons?
Does Group 17 lose or gain electrons? Atoms of group 17 gain one electron and form anions with a 1− charge; atoms of group 16 gain two electrons and form ions with a 2− charge, and so on. What are 4 similar properties of halogens? Halogens share many similar properties including: They all form acids […]
What are the spiral arms of a spiral galaxy made up of?
What sediment type is the rarest found in the ocean?
What sediment type is the rarest found in the ocean? Macroscopic sediments contain large remains, such as skeletons, teeth, or shells of larger organisms. This type of sediment is fairly rare over most of the ocean, as large organisms don’t die in enough of a concentrated abundance to allow these remains to accumulate. What are […]
