What step of the rock cycle happens as the sea stacks are broken down

fiasKO [112]

But rocks are not unchangeable! Just like the water cycle, rocks undergo changes of form in a rock cycle. A metamorphic rock can become an igneous rock, or a sedimentary rock can become a metamorphic one. Unlike the water cycle, you can’t see the process happening on a day-to-day basis. Rocks change very slowly under normal conditions, but sometimes catastrophic events like a volcanic eruption or a flood can speed up the process. So what are the three types of rocks, and how do they change into each other? Keep reading to find out!

A 2.60 kg lion runs at a speed of 5.00 m/s until he sees his prey. The lion then speeds up 8.00 m/s to catch it. How much work d

ELEN [110]

Answer: 50.7 J

Explanation:

Given

mass of lion is $m=2.6\ kg$

The initial speed of the lion is $v_1=5\ m/s$

increased speed of lion is $v_2=8\ m/s$

Initially, its kinetic energy is $K_1=\frac{1}{2}mv_1^2$

Final kinetic energy $k_2=\frac{1}{2}mv_2^2$

work did by lion after speed up is $k_2-k_1$

$\Rightarrow W=\dfrac{1}{2}\times 2.6[8^2-5^2]\\\\\Rightarrow W=1.3\times [39]=50.7\ J$

Light of wavelength 550 nm falls on a slit that is 3.50 x 10^-3 mm wide. How far from the central . maximum will the first diffr

myrzilka [38]

Λ $= 550 * 10^{-9}\] m.

D = 3.50*10^-6 m.$
$d = 10 m. 

m = 1

2x = ?$

Then you need to find x when n=1
or
$sinθ=λ/w=524x10^-9/0.0033=1.59x10^-4$
≈θ for θ<<1 , so θ= $1.59x10^-4 radians$

Then you can find rhe distance of<span> bright fringe from the center:</span> $d= θD=1.59x10^-4x10m ≈ 1.6 mm$

The magnitude of the velocity vector of the car is ∣∣v→∣∣ = 78 ft/s. If the vector v→ forms an angle θ = 0.09 rad with the horiz

kotegsom [21]

Answer:

$\vec{v} = (77.68~{\rm ft/s})\^i + (7.01~{\rm ft/s})\^j$

Explanation:

The x- and y- components of the velocity vector can be written as following:

$\vec{v}_x = ||\vec{v}||\cos(\theta)\^i$

$\vec{v}_y = ||\vec{v}||\sin(\theta)\^j$

Since the angle θ and the magnitude of the velocity is given, the vector representation can be written as follows:

$\vec{v} = 78\cos(0.09)\^i + 78\sin(0.09)\^j\\\vec{v} = (77.68~{\rm ft/s})\^i + (7.01~{\rm ft/s})\^j$
