How does the movement of tectonic plates cause deformation in rocks

1 answer:

4 0

The movement of tectonic plates causes earthquakes when two plates that are in contact with each other move in opposite directions and release built-up stress.<span>For example, one plate may move north, while the other may move south. Stress can build up to a significant amount while the plates are held stationary, but trying to move, which can then be released as an earthquake</span>

kirill [66]

Answer:

Electric potential, $V=3.52\times 10^{12}\ volts$

Explanation:

It is given that,

The magnitude of electric field, $E=4.7\times 10^7\ V/m$

Distance between automobile engines that consists of metal conductors, $d = 0.75\ mm = 7.5\times 10^4\ m$

Let V is the magnitude of the potential difference between the conductors. The relation between the electric field and the electric potential is given by:

$V=E\times d$

$V=4.7\times 10^7\ V/m \times 7.5\times 10^4\ m$

$V=3.52\times 10^{12}\ volts$

So, the magnitude of the potential difference between the conductors is $3.52\times 10^{12}\ volts$ . Hence, this is the required solution.

A pair of closely spaced parallel conducting plates, charged with equal and opposite electric charges, produces a uniform electr

Sedbober [7]

Answer:

Plate B.

Explanation:

If the direction of the electric field is from plate A to plate B, then this means that plate A is positively charged and plate B is negatively charged. If we are to move an electron between the plates, then we should place the electron on plate B, so the negatively charged electron can be attracted by the positive charges on plate A.

A 7.80 g bullet has a speed of 620 m/s when it hits a target, causing the target to move 6.30 cm in the direction of the bullet'

Arada [10]

Answer:

$23796.19\ \text{N}$

$0.0002032\ \text{s}$

Explanation:

F = Force

s = Displacement = 6.3 cm

m = Mass of bullet = 7.8 g

v = Velocity of bullet = 620 m/s

t = Time taken

Work done is given by

$W=Fs$

Kinetic energy is given by

$K=\dfrac{1}{2}mv^2$

Using work energy considerations we get

$Fs=\dfrac{1}{2}mv^2\\\Rightarrow F=\dfrac{1}{2s}mv^2\\\Rightarrow F=\dfrac{1}{2\times 0.063}\times 7.8\times 10^{-3}\times 620^2\\\Rightarrow F=23796.19\ \text{N}$

The average force that stops the bullet is $23796.19\ \text{N}$ .

Force is given by

$F=m\dfrac{v-u}{t}\\\Rightarrow t=m\dfrac{v-u}{F}\\\Rightarrow t=7.8\times 10^{-3}\times \dfrac{620}{23796.19}\\\Rightarrow t=0.0002032\ \text{s}$

The time taken to stop the bullet is $0.0002032\ \text{s}$ .
