When rocks are put under stress, they may fold, causing ________ to form.

1 answer:

3 0

Faults are cracks on the ground that is caused by the movement of the plate tectonics. They usually cause rocks to break.

Anitclines and synclines form when rocks are also put under stress, but they fold, not necessarily break apart. They create sharp folds.

Island arcs are formed through volcanic events and not rocks.

Mid ocean ridges are formed when oceanic plates move apart.

Looking at their differences, the answer to your question is B.

A 59.31 kg rock is sitting at the top of a cliff that is 300 m tall. What is the gravitational potential energy of that rock?

Diano4ka-milaya [45]

Answer:

The gravitational potential energy of that rock is 174371.4 J.

Explanation:

Given

Mass m = 59.31 kg

Height h = 300 m

To determine

We need to find the gravitational potential energy of the rock

We know that the potential energy of a body is termed as the stored energy due to its position.

One kind of energy comes from Earth's gravity — Gravitational potential energy (GPE).

Gravitational potential energy (GPE) can be determined using the formula

$GPE = mgh$

where

$m$ is the mass

$g$ is the gravitational acceleration which is equal to g = 9.8 m/s²

$h$ is the height

GPE is the Gravitational potential energy

now substituting m = 59.31, h = 300 and g = 9.8

$GPE = mgh$

$=59.31\times 9.8\times 300$

$=174371.4$ J

Therefore, the gravitational potential energy of that rock is 174371.4 J.

What is the Gravitational Potential Energy of a 30 kg box lifted 1.5 meters off the ground?

juin [17]

Answer:

Explanation:

The potential energy of a body can be found by using the formula

PE = mgh

where

m is the mass

h is the height

g is the acceleration due to gravity which is 9.8 m/s²

From the question we have

PE = 30 × 9.8 × 1.5

We have the final answer as

The forces in (Figure 1) are acting on a 1.0 kg object.What is ax , the x -component of the object's acceleration

a_sh-v [17]

The x -component of the object's acceleration is 2 m/s².

<h3>What's the resultant force along x- direction?</h3>

Forces along x axis direction are as follows

4N along +x axis, so it's taken as +4 N
2N along -x axis , so it's taken as -2N.

Resultant force along x direction = 4N - 2N = 2 N which is along + ve x direction.

<h3>What's the acceleration along x axis direction?</h3>

As per Newton's second law, Force = mass × acceleration of the object
Force along x axis= mass × acceleration along x axis= 2N
Acceleration = 2/ mass = 2/1 = 2 m/s²

Thus, we can conclude that the acceleration along x axis is 2 m/s².
