As the dust layer is moved to 2000m above the surface, the gravitational force of the particle will decrease due to increase in the distance of separation between the layer of dust particle and the planet.

The balanced force between gravitational force  of the planet and electric force of the dust particles creates equilibrium position for the dust particles.

According Newton's law of universal gravitation, the force of attraction will decrease with increase in the distance of separation.

[tex]F = \frac{GMm}{R^2}[/tex]

Thus, as the dust layer is moved to 2000m above the surface, the gravitational force of the particle will decrease due to increase in the distance of separation between the layer of dust particle and the planet.

Solution :-

As per the provided information in the given question, we have been given that the Area of the block is 0.2 m² . Its Pressure is given 500 Pascal . And, we have been asked to calculate the Weight of that block .

For calculating the Weight , we will use the Formula :-

Therefore , by Substituting the given values in the above Formula :-

⇒ Weight = Pressure × Area

⇒ Weight = 500 × 0.2

⇒ Weight = 100

Contrary to answers a, b, and c, volcanic rocks, like basalt, andesite, and rhyolite, are fine-grained which are extrusive igneous rocks.

Intrusive rocks, also called plutonic rock, are coarse-grained and cool slowly without ever reaching the surface. While intrusive igneous rocks do solidify in the earth they do eventually become exposed by erosion.

The point of origin is the three dimensional location while the point of convergence is the area containing intersections.

Blood pattern analysis is usually used by the forensic specialists to determine the facts surrounding an investigation using physical nature of blood stains.

There are different types of blood analysis but the one that was displayed in the picture is the impact spatter patterns which contains a point of origin and point of convergence.

The point of origin is the three-dimensional location from which blood spatter originated while the point of convergence is the area containing the intersections generated by lines drawn through the long axes of individual stains that indicates in two dimensions the location of the blood source.

Answer:

Two tunnig fork of frequency 520 Hz and 524Hz are vibrated together. It means beats form due to it .

f₁ = 524 Hz

f₂ = 520 Hz

Beat period = 1/number of Bea are formed per unit time

= 1/(f₁ - f₂)

= 1/(524 - 520)

= 1/4 sec

Now, time inveral between successive maximum and minimum intensities = beat period= 1/4 sec

Given what we know, we can confirm that when a light wave is refracted, it changes direction.

Refraction is a term used to explain and describe the change in direction of a light wave as it passes through a medium. This change in direction is caused by the change in speed of the light wave entering a new medium.

Therefore, we can confirm that when a light wave is refracted, it changes direction.
