Answer:

Molecules in the water move in a circular motion

Explanation:

Because of its circular motion it causes the waves to look like open circles which makes it easy for people to surf on

Water molecules move up and forward, down and back, in an overall circular motion in the wave. Therefore, option A is correct.

Circular motion is defined as the movement of an object while rotating in a circle. Circular motion can be uniform or asymmetric.

The angular rate of rotation and speed are constant in uniform circular motion, but the rate of rotation changes in non-uniform circular motion.

This means that circular motion can occur only if there is a "center seeking" force present; otherwise, things will travel in a straight line.

Within the wave, the water molecules move in a circular motion. Each water particle moves in a complete circle during a single wave period. The circle traced by a water particle on the ocean surface as a wave passes a given point has a diameter equal to the height of the wave.

Thus, option A is correct.

nuclear energy originates from the splitting of urinal atoms a process called fish and degeneracy to produce steam which is used by a turbine generator to generate electricity.

Answer:

The answer to your question is A.

D. Protective coloration.  Protective coloration, also known as "crypsis," is a defense mechanism used by animals to avoid detection by predators or prey.

An illustration of protective coloration, which is a sort of camouflage, is how white arctic hares blend in with the white snow around them. Animals use protective coloration, commonly referred to as "crypsis," as a defensive strategy to evade being seen by predators or prey.

In this instance, the white arctic hares' fur is the same shade as that of their snowy environment. Their chances of survival are increased by this merging, which enables them to remain unnoticed and effectively hidden from predators like polar foxes or birds of prey. They have a better chance of escaping or avoiding detection when they are well-camouflaged, making it difficult for predators to see them against the white background.

Ionic compound can conduct electricity

The net force acting on the box is 15 N which is the difference of the two acting forces and the  box shifts to the right in the direction in which greater amount of force is applied.

Force is defined as a cause which is capable of changing the motion of an object. It can cause an object which has mass to change it's velocity. It is also simply a push or a pull . It has both magnitude as well as direction.Hence, it is a vector quantity.

It has SI units of Newton and is represented by'F'.Newton's second law states that force which acts on an object is equal to momentum which changes with time. If mass of object is constant, acceleration is directly proportional to net force acting on an object.

The concepts which related to force are thrust and torque .Thrust increases the velocity of an object and torque produces change in rotational speed of an object.

The transfer of energy between systems through work is the expansion of gas in a steam engine. By doing work or by transferring heat, energy can be transferred. Therefore, option A is correct option.

Energy transfer is a phenomenon in which energy transfer from one matter to another matter. Energy requirement is necessary to move any object so work has to be done by the gas to the piston.

Heat can be transferred by three ways radiation, convention or conduction. In conduction, direct contact of two body is necessary for transfer of molecules. When we touch a shopping cart in the grocery store parking lot, then conduction is the process by which heat is transferred between our hand and the handle.

Therefore, the option A is correct option that is conduction.

Answer:

A) The atoms of the reactants unbond, rearrange and then rebond to form the products

Explanation:

Using method of elimination:

A) The atoms of the reactants unbond, rearrange and then rebond to form the products

This is the correct option. Chemical reactions involves breaking and forming of new bonds.

B) Some atoms disappear while others multiply to form the products

This option is incorrect. Atoms do not disappear

C) The atoms of the reactants always stay together to form the products

This option is incorrect. The bonds between the atoms in the reactants must first be broken before products can be formed.

D) New atoms are formed which combine to make the products

This option is incorrect. Atoms do not just form out of nowhere.

Answer:

1.51 x 10^23 atoms of Ar

Explanation:

Start out with what you're given.

10.0 g of Ar/1 * 1 mol/39.948 g Ar * 6.022*10^23 atoms/1 mol

(It's easier if you write it out.)

You always want to start out w/ what you're given and continue your unit conversions from there. Since you started out with grams of Argon, you want grams of Argon on the bottom to cancel it out. Once you found the unit conversion: 1 mol/39.948 g Ar (molar mass of Ar), now it's time to convert to atoms. Since 1 mol is up on top, put 1 mol on the bottom. Considering you're looking for atoms, use Avagradro's number: 6.022*10^23.

Once simplified, you should get 1.51 x 10^23 atoms of Ar.

Wind and Erosion lead to Washing away of top soil.

Erosion is the process that lead to the washing away of top soil leading to loss of nutrient, holes and many more.

The agents of erosion include wind, water and so on.

Strong wind will lead to the top soil to be remove when it is blowing. Water also when is is flowing turbulently maybe when rain fall can lead to loss of top soil.

Therefore, Wind and Erosion lead to Washing away of top soil.

The percent yield of the reaction would be 85.64%

From the balanced equation of the reaction:

[tex]9 O_2 + 2 Sb_2S_3 ---> 6 SO_2 + Sb_4O_6[/tex]

Mole ratio of Sb2S3 to Sb4O6 is 2:1

Mole of 98.7g Sb2S3 = 98.7/339.7

                                   = 0.29 moles

Equivalent mole of Sb4O6 = 0.29/2

                                            = 0.145 moles

Mass of 0.145 Sb4O6 = 0.145 x 583

                                     = 84.535 g

Percent yield = yield/theoretical yield x 100

                       = 72.4/84.535 x 100

Area of rectangular poster = [tex]\frac{3}{16}[/tex] yard²

Explanation:

P.S - The exact question is -

Given - A rectangular poster is [tex]\frac{1}{4}[/tex] yard wide and [tex]\frac{3}{4}[/tex] yard tall.

To find - What is its area ?

Proof -

We know that ,

The area of rectangle = Length × Breadth

Here,

Given that,

Length of rectangle = [tex]\frac{3}{4}[/tex] yard

Breadth of rectangle = [tex]\frac{1}{4}[/tex] yard

∴ we get

Area of rectangular poster = [tex]\frac{3}{4}[/tex] × [tex]\frac{1}{4}[/tex]  yard²

                                          = [tex]\frac{3}{16}[/tex] yard²

⇒Area of rectangular poster = [tex]\frac{3}{16}[/tex] yard²
