The resultant velocity of a boat is 17 km/hr and the direction of the boat is SW.
that the rock was moved by flowing water.
having low sliding power. The lowest form of viscoity is honey WRONG! viscosity is the tendency of a liquid to keep from flowing-its resistance to flowing. HIGH viscosity is thick substances like HONEY, and low viscosity is thin substances like water
The noun 'race' is a common noun, a general word for any race of any kind.The noun 'race' is an abstract noun as a word for a contest of speed; a word for each of the major divisions of humankind having distinct physical characteristics; a word for a concept.The noun 'race' is a concrete noun as a word for a strong or rapid current flowing through a narrow channel of water; a word for a physical thing.The word 'race' is also a verb: race, races, racing, raced.
Materials that obey Ohm's Law are called 'linear' or 'ohmic'; those that don't are called 'non-ohmic' or 'non-linear'.Ohm's Law isn't by any means a universal law; it doesn't apply to all conductors! Ohm's Law simply states that 'the current flowing through a wire, at constant temperature, is directly proportional to the potential difference across the ends of that wire'. This doesn't apply to, for example, a tungsten filament lamp, whose ratio between voltage and current changes as the voltage increases (due to its resistance changing as its temperature increases).The so-called 'Ohm's Law equation' (R = V/I) is, in fact, derived from the definition of the ohm, and not from Ohm's Law. For this reason, the equation applies even when Ohm's Law does not. If the ratio of voltage to current remains constant over a wide range of voltages, then Ohm's Law applies for that range of voltages. If the ratio of voltage to current changes over a range of volages, then Ohm's Law does not apply.In the case of resistors (as opposed to 'resistance'), 'linear' and 'non-linear' describes the way in which variable resistors have been wound. 'Non-linear' variable resistors are those that have been wound to produce specific characteristics, such as logarithmic values of resistance, as they are adjusted, whereas 'linear' variable resistors produce values of resistance that are directly proportional to how far the adjustment wiper has been moved.
Among other things, 1 ampere is equal to:1 coulomb / second1 volt / 1 ohmBasically, you can understand 1 ampere as a certain amount of electric charge (1 coulomb) flowing past a certain point per second (although in the SI, the definitions are the other way round: the coulomb is a unit derived from the ampere).
it is an instrument to determine the velocity of flow at required point in a flowing stream.
13 meters per second (m/s)
A current of air with its velocity directed downwards or in a direction below the horizontal. Mathematically v.n < 0 where v is the velocity vector and n is the upward normal at the surface.
the flowing in the conductor is related as given by the relation... I=Vena v=drift velocity of electron e=charge on electron n=concentration of electron in the current carrying conductor . a=area
The measurement of how fast the current is flowing is the Ampere.
Flowing electricity is called electric current.
velocity is a distance travelled per sec
Electrons are in random motion in a material, such that there is no resultant electron movement. Hence a material has no current flow by its own. Only the directed flow of this charge in a direction, will results in current. when we provide sufficient energy (for example by mean of applied potential difference ) the net motion of the electron gives rise to the current flow.
EMF (voltage) is the force that keeps current flowing in a circuit.
It measures current by creating a coil around the current carrying wire. Current flowing in the wire induces a current in the amp-meter proportional to the current flowing in the wire.
It is called an alternating current
When a capacitor is discharging, current is flowing out of the capacitor to other elements in the circuit, similar to a battery. Current flowing out of an element, by convention, is defined as negative current, while current flowing into an element, such as a resistor, is defined as positive current. Thus a discharging capacitor will always have a negative current.
