Why is it sometimes difficult for scientists to identify a a fold or fault?

Physics

Folds and faults are difficult to identify because they occur in the interior of rocks and also due to the dense nature of the materials.

<h3>What are faults and folds?</h3>

Faults are lines of weakness are present in materials dues to uneven positioning of the particles of the material.

Folds occurs when infolds occur in materials.

Faults and folds usually occur in rocks.

Folds and faults are difficult to identify because they occur internally and also due to the dense nature of the materials.

A transformer has an output coil with 6 times as many turns as the input coil. If the input frequency is f then the output frequ
sveticcg [70]

Answer:

d. f

Explanation:

Based on the principle of operation of transformer, when a.c voltage is applied at the terminal of the primary coil (input coil), an alternating magnetic flux is produced in the iron core which links the secondary coil (output coil).

Also, an alternating e.m.f of <em>the same frequency</em> as that of primary coil (input coil) <u>will be induced in the secondary coil (output coil) by mutual inductance.</u>

Thus, If the input frequency is "f" then the output frequency will be "f" (since the frequency will be the same).

The correct option is "D"

If a small motor does 520 J of work to move a toy car 260 m, what force does the engine exert on the car?
ohaa [14]

Answer:

<h2>2 N</h2>

Explanation:

The force engine exert on the car can be found by using the formula

f =  \frac{w}{d}  \\

w is the workdone

d is the distance

From the question we have

f =  \frac{520}{260}  = 2 \\

We have the final answer as

<h3>2 N</h3>

Hope this helps you

The fastest measured pitched baseball left the pitcher's hand at a speed of 42.0 m/s. If the pitcher was in contact with the bal
I am Lyosha [343]

Answer:

The acceleration and time are 588 m/s² and 0.071 sec respectively.

Explanation:

Given that,

Speed = 42.0 m/s

Distance = 1.50 m

(a). We need to calculate the acceleration

Using equation of motion

v^2=u^2+2as

a=\dfrac{v^2-u^2}{2s}

Put the value in the equation

a=\dfrac{42.0^2-0}{2\times1.50}

a=588\ m/s^2

(b). We need to calculate the time

Using equation of motion

v = u+at

t=\dfrac{v-u}{a}

t=\dfrac{42.0-0}{588}

t=0.071\ sec

Hence, The acceleration and time are 588 m/s² and 0.071 sec respectively.
