What are the three types of seismic waves?

Answers

Answer 1

Answer: primary waves, secondary waves and surface waves, which arrive at seismic recording stations one after another. Both P and S waves penetrate the interior of the Earth while surface waves do not. Due to this, P and S waves are known as "body waves".

Answer 2

Answer: Earthquakes generate three types of seismic waves: P (primary) waves, S (secondary) waves and surfacewaves, which arrive at seismic recording stations one after another. Both P and S waves penetrate the interior of the Earth while surface waves do not. Due to this, P and S waves are known as "body waves".

How are the types of energy in the electromagnetic spectrum defined? (Points : 3)by their atomic structure

by their color

by their amplitude

by their wavelength

Answers

The energy associated with the electromagnetic spectrum is given by the wavelength of the spectrum.

Further Explanation:

The electromagnetic waves are the waves which travel through the space and do not require any medium for their propagation. The Electromagnetic waves are the waves which are transverse in nature.

There are several waves of various wavelength and frequency present in the Electromagnetic spectrum. The different waves present in the electromagnetic spectrum are:

Gamma rays.

X-rays.

Ultraviolet rays.

Visible rays.

Infrared rays.

Micro waves.

Radio waves.

The wavelength and the frequency of the electromagnetic waves are the key properties of the wave which describe several other parameters of the waves like intensity, power, energy of the wave etc.

The energy associated with the electromagnetic radiation is given by:

$E=\frac{{hc}}{\lambda}$

Here, $E$ is the energy of the radiation, $h$ is the plank’s constant, $c$ is the speed of the light and $\lambda$ is the wavelength of the radiation.

Therefore, the above expression shows that the energy of the electromagnetic spectrum depends on the wavelength of the spectrum.

Thus, Option (d) is correct. The energy of the electromagnetic spectrum is defined by their wavelength.

Answer Details:

Grade: High School

Subject: Physics

Physics: Electromagnetic spectrum

Keywords:

Electromagnetic spectrum, energy, frequency, wavelength, radiation, speed of light, defined by their wavelength, E=hc/lamda, waves, transverse nature.

The correct answer to the question is : C) By their wavelength

EXPLANATION:

Before going to answer this question, first we have to understand the electromagnetic spectrum.

An electromagnetic wave is the transverse wave which contains time varying electric field and magnetic field which are perpendicular to each other as well as perpendicular to the direction of propagation.

There are various electromagnetic waves which are named as gamma ray, X-ray, U.V ray, visible light, infrared wave, micro wave and radio waves respectively. Out of these waves, only visible light can be visualized by human eye.

Every electromagnetic wave is characterized by its wavelength. Different waves have different range of wavelength.

The electromagnetic spectrum is the the arrangement of electromagnetic waves either in ascending order of wavelength or in descending order.

The gamma ray has the minimum wavelength in the spectrum, and radio wave has the maximum wavelength.

The energy carried by electromagnetic waves having wavelength $\lambda$ is calculated as-

Energy = $(hc)/(\lambda)$

Here, c is the velocity of light and h is the Planck' s constant.

Hence, the correct answer to the question is wavelength which will signify the energy of different types of electromagnetic waves.

Joan makes the device shown in her science class.An illustration with a battery and ends labeled positive and negative. A wire is connected to the positive end of the battery and curls around an iron nail and connects back with the negative side of the battery.

What would happen to the magnetic field if she connects the battery in the opposite direction?

The field would stop.
The field would get stronger.
The field would reverse its poles.
The field would get weaker.

Answers

If she connects the battery in the opposite direction, the magnetic field would reverse its poles.

What is magnetic field?

The magnetic field is the region of space where an object experiences the magnetic force and obtain magnetic properties.

A wire is connected to the positive end of the battery and curls around an iron nail and connects back with the negative side of the battery. This arrangement will let the current flow from the positive end of the battery towards the negative terminal of the battery.

If the battery is connected in the opposite direction, the current will flow from negative to positive terminal.

Therefore, If she connects the battery in the opposite direction, the magnetic field would reverse its poles.

Determine the weight of a 2959.0-kg car that is moving at a speed of 21 m/s. Enter anumerical answer.

Answers

The weight of a 2959.0-kg car that is moving at a speed of 21 m / s would be 28998.2 Newtons, here speed of the car is the redundant value that is not used to calculate the weight of the car.

What is gravity?

It can be defined as the force by which a body attracts another body toward its center as the result of the gravitational pull of one body and another.

As given in the problem, we have to determine the weight of a 2959.0-kg car that is moving at a speed of 21 m / s .

The weight of the car = mass of the car × acceleration due to gravity

= 2959 × 9.8

= 28998.2 Newtons

Thus, the weight of a 2959.0-kg car that is moving at a speed of 21 m / s would be 28998.2 Newtons.

What is a major goal of the federal government when managing land resources?

Answers

One of its main objectives is to support the implementation of an efficient land utilization system based on such a Land Resources ManagementSystem (LRMS) and a Geographical Information System (LIS) in order to introduce a digital land reform system.

Afforestation, good grazing and canal maintenance, control of pesticides and agricultural runoff, and correct use of wasteland and fallow land are procedures and measurement that should be implemented to safeguard land resources.

Conservation of Soil and Water in All Places

Terracing and reclaiming, erosion prevention, pumping stations and conservation, tree plantations, the growth of cash and horticultural crops, watershed management projects, the construction of agricultural ponds, and environmental protection projects in urban areas are only a few of the tasks undertaken underneath this scheme.
