What is one reason why rock layers are not horizontal

Answer:

Because of the deposits.

Explanation:

One of the reasons why rocks layers are not horizontal is because of the deposits and kinds of the walls that are next of the deposits

They are not necessarily always parallel. They have a natural inclination delimited by the walls.

This is determined by the age of the strata; the youngest deposits are taking the form of the oldest deposit.

However, part of the unique factors that determine the deposits (shape and alignment) of the layers are the organisms that lived and, therefore, could be fossilized. These factors are not repeatable since they are organisms that will not exist again.

Fossils are an essential part of the Earth's layers, as they help study the stages and shapes of the layers.

There is also another factor when magma is introduced in the form of a fault line and crystallizes in the middle of the Earth's layers. modifying the sequence of the affected rocks, becoming a young layer (not horizontal, due to its penetration into the layers of the Earth).

They are not perfectly horizontal because the wind and earth don't always make perfect lines.

Two forces are applied on a body. One produces a force of 480-N directly forward while the other gives a 513-N force at 32.4-deg

n200080 [17]

Answer:

F = (913.14 , 274.87 )

|F| = 953.61 direction 16.71°

Explanation:

To calculate the resultant force you take into account both x and y component of the implied forces:

$\Sigma F_x=480N+513Ncos(32.4\°)=913.14N\\\\\Sigma F_y=513sin(32.4\°)=274.87N$

Thus, the net force over the body is:

$F=(913.14N)\hat{i}+(274.87N)\hat{j}$

Next, you calculate the magnitude of the force:

$F=\sqrt{(913.14N)+(274.87N)^2}=953.61N$

and the direction is:

$\theta=tan^{-1}(\frac{274.14N}{913.14N})=16.71\°$

Answer:

The average angular acceleration is $\alpha =125.487 rad /s^2$

Explanation:

From the question we are told that

From the question we are told that

The length of the bat is $l = 0.85m$ \

The initial linear velocity is $u = 0 m/s$

The time is $t = 0.15s$

The velocity at t is $v = 16 m/s$

Generally average angular acceleration is mathematically represented as

$\alpha = \frac{w_f - w_o}{t}$

Where $w_f$ is the finial angular velocity which is mathematically evaluated as

$w_f = \frac{v}{l}$

$w_f = \frac{16}{0.85}$

$= 18.823 rad/s$

and $w_o$ is the initial angular velocity which is zero since initial linear velocity is zero

So

$\alpha = \frac{18.823 - 0}{0.15}$

$\alpha =125.487 rad /s^2$

A body is electrically neutral. Does it mean that it has no charge?<br>

vova2212 [387]

Answer:

If a body is electrically neutral it means it has no net charge.

Explanation:

Because it has the same number if protons as it does electron , which are opposite charges that offset eachother.
