Answer:

0.13 m/s^2

Explanation:

acceleration is the change in velocity over time

So, 8-2=4

4/30=0.13

Brainliest pls

he right answer is "0.2 m/s²"

Answer explanation:

Acceleration = change in velocity / time

= (8 m/s – 2 m/s) / 30s

= 0.2 m/s2

Answer: C

Explanation:

The fusion pressure inside of the stars core creates an outward force acting on the star. This pressure is balanced by the inwards gravitational force that the core of the star is experiencing.

Answer:

A black hole cannot eat an entire galaxy.

Some scientists believe that stuff that goes into a black hole might go into another dimension but no one has been able to prove that theory, so most believe that any matter that enters a black hole is torn apart into the smallest components possible and eventually squeezed into a singularity

There is an idea of a Patrick Bateman, some kind of abstraction, but there is no real me, only an entity, something illusory, and though I can hide my cold gaze and you can shake my hand and feel flesh gripping you and maybe you can even sense our lifestyles are probably comparable: I simply am not there.

Answer:

D

Explanation:

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.

Correct me if I'm wrong.

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

The populaton of the world increase at a higher rate due to more children were born as compared to death ratio.

The world population during this time frame, the world population increase at a higher rate because of unawareness and lack of education. People produce more children without knowing their impact on the environment and earth system.

So we can conclude that the populaton of the world increase at a higher rate due to more children were born as compared to death ratio.

Assuming your question is the same as mine, that's the answer I got. This would've been way easier to answer if you at least included answer choices.

Answer:

14 cm

Explanation:

F = (frac{uv}{u – v})

F = +ve

v = -ve

30 = (frac {25 {times} (-v)}{25 – (-v)})

v = (frac {25 {times} (-v)}{25+v})

v = 14cm

(Note that either negative or positive values go to show the positioning and hence, they are not a strong necessity in your final answer.)

One step of copper mining requires blasting ore to be able to blasted and extracted from mine.

Mercury is used to recover minute pieces of gold that is mixed in soil and sediment. Sometimes Mercury can be lost in this process resulting in widespread contamination of local rivers and lakes.

Hundreds of tons of rock are unearthed, moved and crushed in mining operation significantly increasing the amount of dust and particulates in the air.

Strip mining (also known as mountaintop removal) involves scraping away earth and rocks to get to coal buried near the surface. This often results in the destruction of ecosystems.

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.

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.
