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?
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. […]
How can a simple machine reduce force?
How can a simple machine reduce force? A lever makes work easier by reducing the force needed to move a load by increasing the distance. A Lever is a simple machine consisting of a rigid bar that rotates about a fixed point, called a fulcrum. The lever makes doing work easier by reducing the force […]
What is overlap in a camshaft?
What is overlap in a camshaft? Definition & Description. Overlap is when the intake and exhaust valves are open at the same time. It is expressed in degrees of crankshaft rotation. Not all camshafts have overlap. If they do, it happens at the end of the exhaust stroke and the beginning of the intake stroke. […]
Do I disconnect positive or negative first?
Do I disconnect positive or negative first? When disconnecting the cables from the old battery, disconnect the negative first, then the positive. Connect the new battery in the reverse order, positive then negative.” How do you prevent a battery short circuit? Carefully organize your tools close by your work area but away from the batteries, […]
How do you calculate the equilibrium concentration of a vacancy?
How do you calculate the equilibrium concentration of a vacancy? The correct formula is: C=C0 exp-(Q/kT). C0 is not temperature dependent and is defined by the local change of entropy if 1 vacancy is formed. What is equilibrium concentration of vacancies? Vacancies occur naturally in all crystalline materials. At any given temperature, up to the […]
What buffering technique are you using if you choose to praise the receivers accomplishments organization or efforts?
What buffering technique are you using if you choose to praise the receivers accomplishments organization or efforts? What buffering technique are you using if you choose to praise the receiver’s accomplishments, organization, or efforts? You can buffer bad news with a compliment, but do so with honesty and sincerity. What buffering technique are you using […]
What is the simplest machine you can use to make work easier?
What does a mechanical interlock do?
What does a mechanical interlock do? Mechanically interlocked circuit breakers are intended to prohibit both power sources from being simultaneously connected to the load. The interlocking system disables one circuit breaker by mechanically preventing handle movement from the Off position while the other circuit breaker is in the On position. How does an interlock control […]
What does the intake air temperature IAT sensor measure?
What does the intake air temperature IAT sensor measure? The Intake Air Temperature Sensor (IAT) is used by the ECU to determine the temperature of the air entering the engine. This is used in conjunction with the MAP sensor to determine the density and volume of air entering the engine to make the proper fuel […]
