Explanation:

What happens to a digital signal sent using electromagnetic waves as it travels farther from its source?

Solution.

To transmit a signal, the analogue signal is first modulated and converted to digital signals.

The digital signals transmitted through electromagnetic waves like radio wave or microwave can experience attenuation over a long distance as they tend to pass through tissues and wall.

The frequency and the intensity of wave continue to decrease as the wave tend to propagate through the wall and tissues.

To correct this, there must be a device to amplify the signal at the strategic points.

After this, the signal will be demodulated back to the analogue signal.

Therefore, attenuation may occur as the signal tend to pass through the tissues and office walls.

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
