Whenever we represent forces using vectors, we ensure that the vector begins at the point of force exertion. In the case of weight, the point of exertion of the force is known as the center of gravity, which is the point through which the weight of an object can be said to act. Therefore, the downward arrow representing the weight would begin at the center of gravity of the object.
Answer:
2.5 ms
Explanation:
v = Speed of sound in air = 343 m/s
f = Frequency = 200 Hz
Wavelength is given by
In the case of destructive interference, path difference is given by
Delay is givenn by
The minimum headphone delay, that will cancel this noise is 2.5 ms
Speed is not a vector so horizontal speed does not sighify anything. If u meant velocity it vill be same as the initial velocity in horizontal direction
Electric current in a solid metal conductor is caused by the movement of electric charge. An electric current is the flow of electric charge. An electron current, the flow of electrons, contributes to an electric current since the electron 'carries' negative electric charge. The flow of ions also contributes to an electric current in, for example, the electrolyte of an electrochemical cell.
Answer:
The Earth holds livings things and even the layer has more complex layers in it (Also it's not white) And of course there are no oceans.
