Suppose that you needed to tell some friends how to get from point A to point B in a city. The net displacement vector from poin

t A to point B is shown in the figure.(Figure 1) You could tell them that to get from A to B they should go 3.606 blocks in a direction 33.69 ∘ north of east. However, these instructions would be difficult to follow, considering the buildings in the way. You would more likely give your friends a number of blocks to go east and then a number of blocks to go north. What would these two numbers be?

The distance and the direction is 3 blocks East and then 3 blocks North.

<h3>What is distance to be travelled to go from point A to point B?</h3>

Distance is a measure of the space between two points.

Distance follows the path of travel of all object adding up all the spaces between the objects.

Displacement on the other hand is the distance travelled in a specific direction.

Displacement measures the shortest distance between two points in a specified direction.

The displacement of point from A to B is given as 3.606 blocks in a direction 33.69 ∘ north of east.

To determine the distance and direction of travel, the best possible route of travel is moving 3 blocks to the East and then 3 blocks to the North.

In conclusion, the distance travelled follows all the path of travel  to get from one point to another.

How does weak background radiation coming from every direction in the sky support the big bang theory
postnew [5]

Answer:

Option 1

It provides evidence of universe expansion

Explanation:

The Big Bang Theory actually explains the universe as originating from a single point, which expanded as billions of years went by.

The background radiation supports this theory in the sense that if the universe is expanding, this means that the universe is cooling and continuously losing heat, which results in background radiation

The tsunami described in the passage produced a very erratic pattern of damage, with some areas seeing very large waves and near
Lunna [17]

Answer:B. The superposition of waves from the primary source and reflected waves produced regions of constructive and destructive interference.

Explanation: Tsunami is described as several waves originating from a water body mainly an ocean caused by Large scale earth movements taking place under the sea.

Superimposition of wave is the movement of one wave on another,it can be constructive or destructive.

Constructive interference is a wave interference that take place causing the Crest of one wave to align with that of another wave leading to high amplitude.

Destructive interference is a wave interference that take place causing the Trouph of one wave to align with the crest of another wave leading to low amplitude wave.

A plane leaves the airport in Galisteo and flies 170 km at 68.0° east of north; then it changes direction to fly 230 km at 36.0°
luda_lava [24]

Answer:

The direction will be 84.86^\circ and the distance 250.75km.

Explanation:

Let's say A is the displacement vector which represents the first 170km and B the one for the next 230km. Then the components of these vector will be:

A_x=170cos(68^{\circ})\\ A_y=170sin(68^\circ)\\\\B_x=230cos(-36^\circ)\\B_y=230sin(-36^\circ)

The vector which point from the origin to the final position of the plane will be R=A+B. We sum components on <em>x </em>and <em>y </em>independetly (vector property):

R_x=A_x+B_x=170cos(68^{\circ})+230cos(-36^\circ)=63.68km+186.07km=249.75km

R_y=A_y+B_y=170sin(68^\circ)+230sin(-36^\circ)=157.62km-135.19km=22.43km

If \theta is the direction of R then:

tan(\theta )=\frac{R_x}{R_y} ⇒ \theta = arctan(\frac{R_x}{R_y}) ⇒ \theta = 84.86^\circ.

The distance will be given by the magnitud of the vector R:

R=\sqrt{R_x^2 + R_y^2} ⇒ R=\sqrt{R_x^2 + R_y^2} = 250.75.
