When interest is computed on the principal and any previously earned interest then it is called? compound interest: Interest, as on a loan or a bank account, that is calculated on the total on the principal plus accumulated unpaid interest. Is the principal plus earned interest? Compound interest is the addition of interest to the […]

Who needs 609 certification? Any person who repairs or services a motor vehicle air conditioning (MVAC) system for consideration (payment or bartering) must be properly trained and certified under section 609 of the Clean Air Act by an EPA-approved program. All technicians servicing MVAC-like appliances must be certified. What certification is needed for HVAC? Environmental […]

What is the color of fresh apple? green How do I know if my apple is original? Make sure that Serial Number in the device under Settings > General >About matches the Serial Number on the box. If it correctly reports your model of iPhone you are presented with, like model, color and capacity, and […]

How do you find the total power dissipated in a series circuit? Power Rule: P = I × V If a current I flows through through a given element in your circuit, losing voltage V in the process, then the power dissipated by that circuit element is the product of that current and voltage: P […]

Can Apple cider vinegar give you a chemical burn? Apple cider vinegar can cause side effects. For example, applying undiluted vinegar to the skin for long periods can lead to burns and irritation. Do chemical burns go away? The amount of damage to the skin depends on how strong the chemical was, how much of […]

What are the characteristics of structured programming? Structured programming is a program written with only the structured programming constructions: (1) sequence, (2) repetition, and (3) selection. Sequence. Lines or blocks of code are written and executed in sequential order. Repetition. Repeat a block of code (Action) while a condition is true. Selection. What is programming […]

What is caused by ignition of air fuel mixture? During normal ignition, the spark plug fires just before the piston reaches TDC. The flame travels across the combustion chamber igniting the Air/Fuel Mixture. This causes a steady increase in cylinder pressure and forces the piston down on the Power Stroke. This causes a brief, but […]

What are the characteristics of ideal operational amplifier? An ideal op amp is usually considered to have the following characteristics: Infinite open-loop gain G = vout / v. Infinite input impedance Rin, and so zero input current. Zero input offset voltage. Infinite output voltage range. Infinite bandwidth with zero phase shift and infinite slew rate. […]

What is a fix in navigation terms? Usually, a fix is where two or more position lines intersect at any given time. If three position lines can be obtained, the resulting “cocked hat”, where the three lines do not intersect at the same point, but create a triangle, gives the navigator an indication of the […]

What happens when Na+ channels open? Role in action potential. Voltage-gated sodium channels play an important role in action potentials. If enough channels open when there is a change in the cell’s membrane potential, a small but significant number of Na+ ions will move into the cell down their electrochemical gradient, further depolarizing the cell.
