Answer:

The particles that accumulate on the rocks as time passes transform into the so-called integral soil profile. This profile is characterized by having different soil horizons, which are the different processes of soil formation, for example:

-the upper horizon is an area where organic matter accumulates, which provides enough carbon dioxide and some organic compounds.

-the next horizon is what is known as the leaching zone, where the different mineral materials dissolve due to the water that seeps into the soil.

-the next horizon is the so-called accumulation zone, where the chemicals that are dissolved in the filtered water are deposited and transformed into minerals

-the last horizon is the so-called transition zone, where the new material originates.

Soil profile includes all the sections/ horizons of the vertical soil depth from top to bottom including the transitions from one horizon to another. A soil horizon is a distinct layer/section of soil with more or less the same texture. Therefore, a soil profile is made of soil horizons.

PLZ HELP!!! *best answer gets brainliest*

Batteries convert chemical energy into electrical energy. It is able to store electrical energy in the form of chemical energy.
Have you ever seen the two different sides of a battery? One side is often labelled with a positive sign, and the other with a negative sign. Inside the battery are four cells where two processes take place. One process uses electrons, and the other creates electrons. When the electrons flow, it creates electricity.
Drums convert mechanical energy into sound energy.
When a musician bangs his/her drumstick on the drum, the motion makes a sound. This movement turned motion into sound.

The impulse experienced by a body is equivalent to the body’s change in

nika2105 [10]

<h2>Answer: </h2>

Momentum

<h2>Explanation: </h2>

The momentum of a particle is defined as the product of the particle mass and the particle velocity as follows:

$\overrightarrow{p}=m\overrightarrow{v}$

On the other hand, the impulse of a constant force is defined as:

$\overrightarrow{J}=\varSigma\overrightarrow{F}(t_{2}-t_{1})=\varSigma\overrightarrow{F}\Delta t$

We also know that the net force acting on a particle equals the rate of change of the particle’s momentum, so:

$\varSigma\overrightarrow{F}=m\overrightarrow{a}=m\frac{d}{dt}(\overrightarrow{v})=\frac{d}{dt}(m\overrightarrow{v})=\frac{d\overrightarrow{p}}{dt}$

If the force is constant, then $\frac{d\overrightarrow{p}}{dt}$ equals the total change in momentum over a period of time:

$\varSigma\overrightarrow{F}=\frac{\overrightarrow{p_{2}}-\overrightarrow{p_{1}}}{t_{2}-t_{1}} \\ \\ \varSigma\overrightarrow{F}(t_{2}-t_{1})=\overrightarrow{p_{2}}-\overrightarrow{p_{1}} \\ \\ \boxed{\overrightarrow{J}=\Delta \overrightarrow{p}}$

Why the temperature of a resistor increase when a current pass through it

Kazeer [188]

Answer:

So, when an electrical charge passes through a resistor, some of that electrical energy is transferred into heat, increasing the temperature. This extra energy causes the particles in the resistor to vibrate more. With these particles moving more, it is more difficult to for the electrons to move through the resistor.
