Distance is 33 km, displacement is 3 km east

Explanation:

- Distance is a scalar quantity equal to the total length of the path covered by an object during its motion, regardless of its direction.

- Displacement is a vector connecting the starting position of motion of an object to its final position. It is a vector quantity, therefore it has both magnitude and direction.

In this problem, the motion of the person is:

12 km north

6 km east

12 km south

3 km west

Therefore, the distance is:

$d=12+6+12+3=33 km$

The displacement instead can be calculated by comparing the final position with the initial position. We notice that:

- the person goes 12 km north and 12 km south, so he didn't move in the north-direction

- The person goes 6 km east and 3 km west, so his final position is 3 km east

Therefore, the displacement is 3 km east.

When is the pressure of the man on the ground more – lying position or standing

Wittaler [7]

Hi,

<u>The man on the ground in standing position has more pressure</u>. This is because when he stands, only his legs are in contact with the ground. While lying, his body is more in contact with the ground, therefore, he exerts less pressure.

To the point, a man standing position on the ground had more pressure.

More is the area of contact, less is the pressure efforted.

Thank you...

A single-slit diffraction pattern is formed on a distant screen. Assuming the angles involved are small, by what factor will the

Novay_Z [31]

Answer:

It will be cut in half

Explanation:

The diffraction of a slit is given by the formula

a sin θ = m where

a = width of the slit,

λ = wavelength and

m = integer that determines the order of diffraction.

Next we divide both sides by a, we have

sin θ = m λ / a

Also, recall that

a’ = 2 a

Then we substitute in the previous equation

2asin θ' = m λ, if divide by 2a, we have

sin θ' = (m λ / 2a).

Now again, from the first equation, we said that sin θ = m λ / a, so we substitute

sin θ ’= sin θ / 2

Then we use trigonometry to find the width, we say

tan θ = y / L

Since the angle is small, we then have

tan θ = sin θ / cos θ

tan θ = sin θ, this then means that

sin θ = y / L

we will then substitute

y’ / L = y/L 1/2

y' = y / 2

this means that when the slit width is doubled the pattern width will then be halved
