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

1 answer:

4 0

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 potter's wheel moves uniformly from rest to an angular speed of 0.16 rev/s in 31 s. (a) Find its angular acceleration in radia

dem82 [27]

Answer:

a) 0.0324 rad/s²

b) 2.01 rad/s , the final angular speed gets doubled

Explanation:

w₀ = initial angular speed = 0 rad/s

w = final angular speed = 0.16 rev/s = 0.16 (6.28) = 1.005 rad/s

t = time interval = 31 s

α = angular acceleration

final angular speed is given as

w = w₀ + α t

1.005 = 0 + α (31)

α = 0.0324 rad/s²

After the acceleration is doubled

α' = 2 α = 2 (0.0324) = 0.0648 rad/s²

w' = final angular speed

w'₀ = initial angular speed = 0 rad/s

final angular speed is given as

w = w₀ + α t

w = 0 + (0.0648) (31)

w = 2.01 rad/s

yes the final angular speed gets doubled

Bumek [7]

Answer:

Both objects will undergo the same change in velocity

Explanation:

m = Mass of the Earth = 5.972 × 10²⁴ kg

G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²

r = Radius of Earth = 6371000 m

m = Mass of object

Any object which is falling has only the acceleration due to gravity.

$ma=\dfrac{GMm}{r^2}\\\Rightarrow a=\dfrac{GM}{r^2}\\\Rightarrow a=\dfrac{6.67\times 10^{-11}\times 5.972\times 10^{24}}{(6.371\times 10^6)^2}\\\Rightarrow a=9.81364\ m/s^2$

The acceleration due to gravity on Earth is 9.81364 m/s²

So, the speeds of the objects will change at an equal rate of 9.81364 m/s² but the change will be negative when an object is thrown up.

Hence, both objects will undergo the same change in velocity.
