Why do faults often occur along plate boundaries?

Answers

Earthquakes can also occur far from the edges of plates, along faults. Faults are cracks in the earth where sections of a plate (or two plates) are moving in different directions. Faults are caused by all that bumping and sliding the plates do. They are more common near the edges of the plates.

94. While you are traveling in a car on a straight, level interstate highway at 90 km/h another car passes you in the same direction, its speedometer reads 120 km/h (a) What is your velocity relative to the other driver? (b) What is the other car's velocity relative to you?

Answers

Answer:

a) $v_{A_(B)}$ = -30 m/s

b) $v_{B_(A)}$ = 30 m/s

Explanation:

Consider the car A travel at a velocity of $v_(A)$ = 90 km/h and the car B travel at the velocity of $v_(B)$ = 120 km/h. As the velocity of the car B is greater than the car A, So it cross the car A. Consider The velocity of car A relative to car B is $v_{A_(B)}$ and it is equal to the velocity of car A minus the velocity of car B.

$v_{A_(B)}$ = $v_(A)$ - $v_(B)$

$v_{A_(B)}$ = 90 - 120

$v_{A_(B)}$ = -30 m/s

Consider The velocity of car B relative to car A is $v_{B_(A)}$ and it is equal to the velocity of car B minus the velocity of car A.

$v_{B_(A)}$ = $v_(B)$ - $v_(A)$

$v_{B_(A)}$ = 120 - 90

$v_{B_(A)}$ = 30 m/s

Which property is shown by the rails of a railway track?A) perpendicularity
B) parallelism
C) intersecting lines
D) opposites

Answers

Parallelism is a property shown by the rails of a railway track.

Option B

Explanation:

Parallelism is the property of the lines which do not meet in a plane, those lines which "do not intersect or touch each other" are parallel to each other.

In the given example, railway lines of railway track are said to be parallel since they are at an equal distance to each point so that the wheels of the train be on track. Since these railway lines do not meet each other even at infinity, they are said to be parallel.

Answer:

parallelism

Explanation:

i took the quiz on Edge 2020 and got it right i promise :)

also this question is mostly based on common sense because if two lines will never intersect they are parallel and train tracks will never intersect so they are also parallel and they only word there that has parallel in it is parallelism so the answer has to be parallelism.

A student claims that any object in motion must experience a force that keeps it in motion. Do you agree or disagree? Explain your reasoning.

Answers

Answer: agree

Explanation: because there is always a force that causes motion..

Also I’m back

Where’s the old gang?

Final answer:

Newton's first law of motion states that an object in motion will continue to move at a constant speed in a straight line unless acted upon by an external force. So, not all objects in motion require a force to keep them in motion.

Explanation:

According to Newton's first law of motion, an object in motion will continue to move at a constant speed in a straight line unless acted upon by an external force. So, it is not true that any object in motion must experience a force to keep it in motion. The force is only necessary to change the object's state of motion, such as slowing it down or altering its direction.

For example, imagine a hockey puck sliding on a frictionless ice rink. Once given an initial push, the puck will continue moving at a constant speed in a straight line until it encounters an external force, such as contact with the boards or another player.

Therefore, I disagree with the student's claim. An object in motion does not necessarily need a force to keep it in motion, but rather a force is required to change its state of motion.
