Do you think that the volume control on an audio amplifier is calibrated in intensity or intensity level? In other words, if you turn your stereo half way down, have you cut the power in half or cut the decibel level in half? Explain

the intensity is reduced

Explanation:

In electronic equipment, the volume is controlled by the power supplied to the speakers, the power is given by the formula

         P = V I

In general, it is easier to control the voltage =, as important as this is a linear relationship, so by lowering the selector the controlled variables V or I decreases by half, so the intensity decreases at half.

In summary the intensity is reduced

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

answer; how far out of place which the object finished relative to the starting location;
