Answer:

B. Law of Conservation of Mass

Explanation:

In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction. If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system.

All waves have the same  wavelength.   wrong

Radio telescopes give us  information about the birthplace of a star.  I think wrong but I'm not sure.

If the wavelength of a wave  increases, its frequency  also increases.   wrong

Visible light is a kind of  electromagnetic wave.   right

All objects emit  electromagnetic waves. right

All waves have the same wavelength is an incorrect statement.

Radio telescopes give us information about the birthplace of a star is a correct statement.

If the wavelength of a wave increases, its frequency also increases is an incorrect statement.

Visible light is a kind of electromagnetic wave that is a correct statement

All objects emit electromagnetic wave is a correct statement

Electromagnetic waves are waves that are generated as a result of oscillation between an electric field and a magnetic field. In other words, EM waves are a combination of vibrating magnetic and electric fields and these two fields are orthogonal to each other. Electromagnetic waves propagate in a transverse direction therefore these waves are also known as transverse waves.

Therefore, it is incorrect to say that all waves have the same wavelength.

It is true to say that radio telescopes can tell us where a star was born.

It is untrue to say that as a wave's wavelength increases, so does its frequency.

It is true to say that visible light is a type of electromagnetic wave.

It is true to say that all objects emit electromagnetic waves.

Answer:

Explanation:

According to equation of motion;

\sum F = ma

m is the mass of the body

a is the acceleration

\sum F = Fm - Ff (along the horizontal)

Fm is the moving force

Ff is the frictional force

Given;

Fm = 12N

Ff = nR = nmg

Ff = n(4)(9.8)

Ff = 39.2n

Substitute the given value into the expression above;

Fm - Ff = ma

12 - 39.2n = 4(2)

-39.2n = 8-12

-39.2n = -4

n = 4/39.2

n = 0.1

Hence the coefficient of kinetic friction between the table and jug is 0.1

Interplanting is the practice of planting a fast-growing crop between a slower-growing one to make the most of your garden space. ... Intercropping enables you to boost the health of all plants because it can enhance soil fertility and cooperation among different plants.

Intercropping refers to large, often commercial, farming operations and is the procedure of planting alternating crop rows. Growing two or more crops in close proximity is known as intercropping.

Starting to grow two or more crops in close vicinity is known as intercropping.

The most common goal of intercropping is to increase yield on a given plot of land by utilizing resources that would otherwise go unused by a single crop.

Intercropping is the cultivation of more than one crop in the same space at the same time. Intercropping is the simultaneous planting of two or more species in a mixture, or the interplanting of one species during the growth of another.

The terms are frequently and regionally used interchangeably. Intercropping is the practice of planting alternating crop rows in large, often advertising, farming operations.

Thus, this is the difference between intercropping and interplanting.

Answer:

The answer is C Skeletal System

Answer:

I = 0.75 Amp

Explanation:

Ohm's Law

Ohm's law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points. The constant of proportionality is called the Resistance (R) of the conductor.

The formula can be expressed as:

V = I.R

The intensity of the current through a resistor can be calculated by solving the equation for I:

[tex]\displaystyle I=\frac{V}{R}[/tex]

A flashlight bulb is an example of a resistor with the specific task to emit light when it's hot enough.

The potential difference (or voltage) is V=6 V and the resistance is R=8Ω, thus the current is:

[tex]\displaystyle I=\frac{6~V}{8~\Omega}[/tex]

I = 0.75 Amp

Answer:

Clear-cutting eliminates all trees leaving none behind to maintain soil fertility or house native animals.

Explanation:

edge 2022

A forestry/logging practice known as clear-cutting, clear felling, or clear-cut logging involves consistently cutting down the majority or all of the trees in a given region. Foresters utilize it to cultivate particular types of forest ecosystems and to advance particular species, in addition to harvesting shelter wood and seed trees.

The removal of a forest or tree stands from land before it is used for a purpose other than as a forest is known as deforestation or clearing of forests. The use of forest land for urban, agricultural, or ranch purposes is referred to as deforestation. In tropical rainforests, there is the greatest concentration of deforestation. Forests currently cover about 31% of the Earth's land area. With half of that loss occurring in the previous century, this is a third less forest cover than there had before agriculture's growth.

As a result of clear-cutting, no trees are left to protect the topsoil or serve as a haven for wildlife. In turn, this causes soil erosion and soil fertility to be destroyed, as well as the removal of the trees required to produce seeds for natural forest development to continue. Animal populations are also pushed out of their natural habitats by clear-cutting, forcing them to look for new homes.

Answer: C

Explanation: Mass is eliminated when equating elastic potential energy with kinetic energy.

Mass is eliminated when equating gravitational potential energy with kinetic energy. Therefore option D is correct.

The energy that an item has or acquires when its location changes as a result of being in a gravitational field are known as gravitational potential energy. Gravitational potential energy can be defined as energy that has a connection to gravitational force or gravity.

The energy of gravity, or gravitational potential energy, is also related to the Earth. An object has gravitational potential energy if it is at a certain height above the Earth's surface. The object's potential energy is transformed into kinetic energy when it is released. Due to the rule of conservation of energy, the sum of the two is always constant.

The test object is positively pulled by the gravitational force from infinity to a location inside the gravitational field. Because gravitational force is inverse square, it is 0 at infinity. As a result, infinity is used as the starting point.
