Answer:

1) dist 10m, displacement 0m

2) dist 7m, displacement 3m

3) dist 13m, displacement 7m

Explanation:

Distance is the total distance travelled (2 distances added), but displacement is where you end up relative to where you started.

Think of it like a number line. When you move east, you are adding 5, and when you move west, you are subtracting 5. In total, you have walked 10 meters, but overall you ended up in the same place.

If you want to have a physical demonstration of this concept, take 5 steps left and 5 steps right, and do the same with the other examples. You will probably get a fuller understanding of this concept.

The wavelength of a wave is 2) A) the distance between two adjacent peaks of the wave. B) equal to the speed of the wave times t

Anton [14]

Answer:

Wavelength = the distance between two adjacent peaks of the wave.

Explanation:

The wavelength of a wave is defined as the distance between two adjacent peaks of the wave or it is defined as the distance between two consecutive crests and troughs. It is denoted by $\lambda$ . Its SI unit is meters.

The relation between the frequency and the wavelength is given by :

$v=\nu\times \lambda$

Where

v is the speed

So, the correct option is (a). " the distance between two adjacent peaks of the wave".

Which statement is true of the energies of the bonds that break and form during the reaction? which statement is true of the ene

Inga [223]

<span>The statement that is true of the energies required to break bonds is this:

the energy needed to break the required bonds is greater than the energy released when the new bonds form.

Bonds that have been formed during specific reactions require much energy to be broken down again because of the closed atomic bond that have formed during the process.</span>

In what way did the cloud model resemble the Bohr model

Ahat [919]

Answer:

While Bohr's atomic model hypothesizes that electrons move in particular energy levels around the nucleus, the electron cloud model suggests that electrons move in an unpredictable pattern but are more likely to be in certain regions than others.

78. A film of oil on water will appear dark when it is very thin, because the path length difference becomes small compared with

Hoochie [10]

To solve this problem it is necessary to apply the concepts related to the condition of path difference for destructive interference between the two reflected waves from the top and bottom of a surface.

Mathematically this expression can be described under the equation

$\delta = 2nt$
