Sunlight heating the sand on the beach on a hot summer day is an example of radiation which is electromagnetic radiation.

The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.

The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.

In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

Adhesion

Explanation:

Water is soaked up by a paper towel because the forces of adhesion exceeds the forces of cohesion.

The forces of adhesion binds the water molecule to the paper towel while the forces of cohesion binds the water molecules to each other.

Adhesion of water to the walls of the paper exerts an upward force that draws water molecules up the paper.

Hence, the movement of water up a paper towel occurs when the forces of adhesion to the walls of the paper is greater than the forces of cohesion acting between the water molecules.

um this is kinda weird I am take a guest SIF4

The formula that represents a tetrahedral molecule is SiF₄. The correct option is the fourth option - SIF4

From the question,

We are to determine which of the given formulae represents a tetrahedral molecule

In order to determine the molecule that represents a tetrahedral molecule, we will determine which of the molecules has a tetrahedral molecular geometry.

A tetrahedral molecular geometry has a central atom located at the center with four substituents that located at the corners of a tetrahedron

Among the given options, the molecule that has four substituents is SiF₄. Si is the central atom and the F atoms are the substituents.

Hence, the formula that represents a tetrahedral molecule is SiF₄. The correct option is the fourth option - SIF4

Answer:

Mixtures can be physically separated by using methods that use differences in physical properties to separate the components of the mixture, such as evaporation, distillation, filtration and chromatography.

Answer:

Dana filtered the sample and larger granules of the sample were left behind.

Explanation:

If a substance is pure, it will have a uniform composition throughout. It will not separate into particles of various sizes.

One of the characteristics of pure substances is that they are homogeneous. A mixture is definitely made up of particles of various sizes.

Since the particles was filtered and larger granules were left behind, the sample has been separated by a physical method (filtration). Only a mixture can be separated by physical methods. It is not a pure substance.

Answer:

cnidarians, mollusks, annelids, arthropods,

Explanation:

Living organisms have been grouped using a system of classification that runs from Kingdom to Species. One of those kingdoms is KINGDOM ANIMALIA, which consists of animal species i.e. organisms that are strictly heterotrophic and eukaryotic.

The next taxa after kingdom is PHYLA. According to this question, the phyla which consists of only animals are cnidarians, mollusks, annelids, arthropods. Other options contain ferns, mosses, and flowering plants which belong to Kingdom Plantae.

Answer:

a) The balloon filled with helium will float higher because helium is less dense than gas X

Explanation:

Since gases are known to not have fixed density, they take up the density of their containers, let us find the density of the gas in first balloon.

 Density is the mass per unit volume;

         Density  = [tex]\frac{mass}{volume}[/tex]  

Insert the parameters and solve;

    mass of gas  = 7.52g

     volume of the gas  = 27.8L

          Density  = [tex]\frac{7.52}{27.8}[/tex]   = 0.271g/L

Let us compare the two densities;

 Density of gas  = 0.271g/L

 Density of helium  = 0.179g/L

We see that the density of the gas is higher than that of helium, so, it not float as high as the balloon with helium. The balloon with helium is lighter.

Mouth is typically large in case of crocodile and comparatively small in sheep and gorilla.

In crocodile more sharp teeth are present as compared to sheep and gorilla for mastication of food and capturing the prey like fish or large animals like zebra.

The crocodile palate is more stronger than sheep and gorilla because it enable it to chew the bones of the prey.
