Explain how a rock with vesicular texture could form. Give two examples of rocks with this texture.

The characteristics of electromagnetic waves typically represent as follows:

• There are changes in the electric and magnetic fields simultaneously so that both fields have maximum and minimum values ​​at the same time and place.
• The direction of the electric field and the magnetic field are perpendicular to each other. The direction of both is perpendicular to the direction of the wave propagation.
• The shape of electromagnetic waves is transverse waves.
• It has general wave characteristics like polarization, reflection, refraction, interference, and diffraction.
• The amount of the electric field (E) is directly proportional to the magnitude of the magnetic field, with the relationship E = cB.
• The universal constant of the velocity of electromagnetic waves in a vacuum is
• The speed at which electromagnetic waves propagate depends merely on the electrical and magnetic properties of the medium that it travels on.
• Because electromagnetic waves do not contain an electric charge, they do not experience any possible deviation in the electric or magnetic fields.

Further explanation

• Two physicists who contributed significantly to developing the concept of electromagnetic waves are Faraday and Maxwell around 1831-1864.
• From the observations, Faraday suggested that changes in the magnetic field cause an electric charge to flow in the loop of wire, contributing in the emergence of an electric field.
• Maxwell proposed a reverse process, which is a change in the electric field will generate a magnetic field.
• As follows, according to Faraday's Law, changes in sinusoidal magnetic fields generate electric fields which also change sinusoidally.
• Meantime, according to Maxwell's Hypothesis, changes in sinusoidal electric fields generate magnetic fields which also change sinusoidally.
• Furthermore, there is a process of combining electric and magnetic fields that propagate in all directions called electromagnetic waves.

Answer: reflection

Refraction

Energy

Speed

Explanation:

Reflection results when em wave hits a plane surface and returns in the same angle it incident

Refraction is the change in velocity and direction of em wave as it crosses boundaries of different medium

The energy of em wave is evenly distributed in electric field and magnetic field

The speed of em wave is the same as 3×10^8

Answer:

Explanation:

At t = 1 velocity = 0

At t = 3 velocity = 3

slope of the line = 3-0 / 3-1 = 3/2

At t = 2

velocity = 3/2 x ( 2 - 1 )

= 1.5 m /s

velocity at t = 2 is 1.5 m /s

Position at t = 2 :

displacement at t = 2

area of graph upto  t = 2

= 1 / 2 x 1 x 1.5 = .75

position at t = 2 :

= initial position + displacement

= 10 + .75 = 10.75 m

position at 6 s :

displacement at t = 6

area of curve upto  t = 6

= 1 / 2 x 2 x 3 +  3 x 3 + 1/2 x 3 x ( 4.5 - 3 )

= 3 + 9 + 2.25

= 14.25 m

position at t = 6

= initial position + displacement

= 10 + 14.25 = 24.25 m

position at 9 s :

displacement at t = 9

area of curve upto  t = 9

= 1 / 2 x 2 x 3 +  4 x 3 + 1/2 x 4 x ( 5 - 3 )- 1/2 x 2 x 1.5

= 3 + 12 + 4 - 1.5

= 17.5  m

position at t = 9

= initial position + displacement

= 10 + 17.5 = 27.5  m

Answer:

I think the Answer is B. Longitudinal waves

Answer: True

Explanation:

A chemical reaction in which the oxidation number of an atom, ion or molecule changes due transfer of electrons between two reactants is known as oxidation-reduction reaction or redox reaction. In Redox reaction, the oxidising agent brings oxidation by gaining electrons and reducing it self.

Example:

Zn + Cu²⁺ → Zn²⁺ + Cu

Here, Cu²⁺ is an oxidizing agent which got reduced to Cu .

Thus, the given statement is true.

Final answer:

It's true that in an oxidation-reduction reaction, the oxidizing agent always undergoes reduction. The oxidizing agent is a substance that is capable of oxidizing other substances, meaning it causes them to lose electrons. By taking these electrons, the oxidizing agent itself is reduced.

Explanation:

In an oxidation-reduction reaction, also known as a redox reaction, the statement that the oxidizing agent always undergoes reduction is indeed true. The oxidizing agent is a substance that has the ability to oxidize other substances, meaning it causes them to lose electrons. In taking these electrons, the oxidizing agent itself is reduced. This is due to the principle that in a redox reaction, when one substance is oxidized (loses electrons), another substance must be reduced (gain electrons).

Answer:

Car B

Explanation:

Inertia of a body is the property to oppose its state of rest or state of uniform motion. It is also equivalent to the measure of its mass. Newton's first law of motion is also called as law of inertia.

According to given question, we have to write the name of car having more inertia. So, the body having more mass will have more inertia.

The mass of car A is 1500 kg while the mass of car b is 2000 kg. Hence, car B will have more inertia.
