The best known source of petrified wood is located in A Arizona

Answer:

Arizona.

Explanation:

Petrified Forest National Park is an American national park in Navajo and Apache counties in northeastern Arizona. Named for its large deposits of petrified wood, the park covers about 346 square miles (900 square kilometers), encompassing semi-desert shrub steppe as well as highly eroded and colorful badlands.

PLS HELP NOW!! I WILL GIVE LOTS OF COINS! In general, explain the amount of force that is applied to both objects during ANY
collision, no matter how big or small, the weight/mass, or velocity of the objects.

Answers

In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction. Such forces often cause one object to speed up (gain momentum) and the other object to slow down (lose momentum). According to Newton's third law, the forces on the two objects are equal in magnitude.

In a collision, there is a force on both objects that causes an acceleration of both objects; the forces are equal in magnitude and opposite in direction. For collisions between equal-mass objects, each object experiences the same acceleration.

define acceleration

Answers

Answer:

In mechanics, acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities. The orientation of an object's acceleration is given by the orientation of the net force acting on that object

Which of the following forces has not changed Earth's surface?

folding
erosion
weathering
gravity

Answers

Answer:Gravity is the force among the options listed that has not directly changed Earth's surface.

Explanation:

Gravity is a fundamental force that acts on all objects with mass, including the Earth itself, but it does not cause changes or modifications to the Earth's surface features. Instead, gravity influences the movement of materials and the shape of the Earth's surface by exerting a pulling force on objects. On the other hand, folding, erosion, and weathering are all processes that directly contribute to shaping

Which statement is best supported by the table? Wave W and Y are light waves, Wave Z is a sound waves, and it is impossible to tell what kind of wave Wave X is. Wave W is a light wave, Waves X and Y are sound waves, and it is impossible to tell what kind of wave Wave Z is. Waves W and Z are sound waves, and Waves X and Y are light waves. Wave W is a sound wave, Waves X and Y are light waves, and it is impossible to tell what kind of wave Wave Z is.

Answers

Answer:

Wave W is a sound wave, Waves X and Y are light waves, and it is impossible to tell what kind of wave Wave Z is.

Explanation:

W      travels fastest through metal

X       travels fastest through air,

Y       travels more slowly through water than air    

Z       travels more slowly at cool temperatures

W appears to be sound wave  as sound travels fastest through metal .

X appears to be light wave as light travels fastest in air .

Y also appears to be light wave as  speed of light is reduced when it passes from air to water .

Z  It is impossible to tell anything about the nature of Z wave .

Answers

Answer:

Radio waves and the are various frequencies of radio waves are used for television and FM and AM radio broadcasts, military communications, mobile phones, ham radio, wireless computer networks, and numerous other communications applications. They are important because Radio waves are very widely used in modern technology for fixed and mobile radio communication, broadcasting, radar and radio navigation systems, communications satellites, wireless computer networks and many other applications.

Microwaves are widely used in modern technology, for example in point-to-point communication links, wireless networks, microwave radio relay networks, radar, satellite and spacecraft communication. They are important because microwaves play an increasingly wide role in heating and cooking food. They are absorbed by water and fat in foodstuffs (e.g., in the tissue of meats) and produce heat from the inside. In most cases, this reduces the cooking time a hundredfold.

How would the scientist most likely use this technology?

2 to predict the star count over a broad area
3 to write observations about what the sky looks like
4 to count the number of visible stars in the sky

Answers

Answer:

It would most likely be 3!

Explanation:

A scientist taking photos of the stars would be using those photos as a sort of documentation. The only reason to record this is for data or research purposes, meaning that 1 and 2 are incorrect. While 4 is a possibility, it is a fruitless endeavor, as even if you managed to count all the stars in the night sky at one point, it would completely discount every star not visible from that part of the globe, making the data false/pointless. Again, this is just my educated assumption, but I do think the answer is 3. Good luck :D

Answer:

39,200J

Explanation:

just took the test

The meteor's potential energy if it has a mass of 10kg at an altitude of 400 m will be 39200 J

What is potential energy ?

Potential Energy that depend upon the relative position of various parts of system . It is an energy possessed by an object by virtue of its position or configuration.

mass(m)  = 10kg

g (acceleration due to gravity) = 9.8m/s^2

altitude(height (h)) = 400m

Meteor's Potential energy = m * g * h

                                           = 10 * 9.8 * 400 = 39200 J

correct option will be a) 39200 J
