Answer:

Lower pressure causes the papers to move closer to each other.

Explanation:

As we know by Bernoulli's principle

P + \frac{1}{2}\rho v^2 = constant

so here when air between the two papers is at normal situation then let say the pressure between the two papers is P_o

now if the air between two papers is blown by straw then the speed of air between two papers will increase.

So as per the equation above the pressure will decrease as the sum of pressure and kinetic energy per unit volume must be constant.

So here the pressure between two papers will decrease due to which the two papers will come closer to each other.

so correct answer will be

Lower pressure causes the papers to move closer to each other.

Higher the pressure the air would spread apart causing the paper to move to the other side. So higher pressure causes the papers to move farther apart.

On the way home from school, Taylor's car runs out of gas. He has to walk 25m north and 10m west in order to reach the nearest g
spin [16.1K]

Answer:

<em>The distance is 35 m and the magnitude of the displacement is 26.93 m</em>

Explanation:

<u>Displacement  and Distance</u>

These are two related concepts. A moving object constantly travels for some distance at defined periods of time. The total distance is the sum of each individual distance the object traveled. It can be written as:

dtotal=d1+d2+d3+...+dn

This sum is calculated independently of the direction the object moves.

The displacement only takes into consideration the initial and final positions of the object. The displacement, unlike distance, is a vectorial magnitude and can even have magnitude zero if the object starts and ends the movement at the same point.

Taylor walks 25 m north and 10 m west. The total distance is the sum of both numbers:

d = 25 m + 10 m = 35 m

To calculate the displacement, we need to know the final position with respect to the initial position. If we set the coordinates of Taylor's car as the origin (0,0), then his final position is (-10,25), assuming the west direction is negative and the north direction is positive.

The magnitude of the displacement is the distance from (0,0) to (-10,25):

D=\sqrt{(25-0)^2+(-10-0)^2}

D=\sqrt{625+100}=\sqrt{725}

D = 26.93 m

The distance is 35 m and the magnitude of the displacement is 26.93 m
