Explain how surface and subsurface events are integral parts of the rock cycle.

vagabundo [1.1K]

Example of surface events are erosion and weathering. Erosion is the carrying of a particle from one place to the other and weathering is the breaking down of particles. These processes help in rock formation because this allows physical changes (grouping together or breaking down) on a certain substance. Subsurface events are those which happened underground such as the flow of underground water which subsequently allow the deposition of minerals, etc.

Car a with mass 1,783 kg collides with stationary 1600 kg car b. they become locked together after the collision and move with s

ValentinkaMS [17]

The initial speed of car A is 15.18 m/s.

Momentum is defined as mass in motion. If there are two objects (the two objects in motion or only one object in motion and the other in stationary) that collide and no other forces work in the system, the law of momentum conservation applies in the system.

p=p'

pa+pb = pa'+pb'

(ma×va) + (mb×vb) = (ma×va') + (mb×vb')

ma = mass of object A (kg) = 1,783 kg
mb = mass of object B (kg) = 1,600 kg
va = speed of object A before collides (m/s)
va' = speed of object A after collides (m/s) = 8 m/s
vb = speed of object B before collides (m/s) = 0 m/s
vb' = speed of object B after collides (m/s) = 8 m/s
p = momentum before collision (Ns)
p' = momentum after collision (Ns)

(ma×va) + (mb×vb) = (ma×va') + (mb×vb')

(1,783×va) + (1,600×0) = (1,783×8) + (1,600×8)

(1,783×va) + 0 = 14,264+12,800

(1,783×va) = 27,064

$va \:=\: \frac{27,064}{1.783}$

va = 15.18 m/s

Gold is classified as a: O noble gas O halogen O transition metal O nonmetal

dedylja [7]

Answer:

Transition metal.

Explanation:

Reason;in periodic table gold is third element in eleventh column. So its classified as TRANSITION METAL. Gold contain 79 protons, 79 electrons and 118 neutrons and gold is the most abundant isotope.

A boy runs 40m towards east. he then walks 30m towards north. The boy again runs 50m towards north making an angle of 30° with e

Katena32 [7]

Answer: The displacement is 99.82 meters.

Explanation:

To use a standard notation, we can define:

North as the positive y-axis.

East as the positive x-axis.

If the initial position of the boy is (0, 0)

Then:

"runs 40m towars the east"

The new position is (0, 0) + (40m, 0) = (40m, 0)

"he then walks 30m towards North"

The new position is: (40m, 0) + (0, 30m) = (40m, 30m)

"The boy again runs 50m towards north making an angle of 30° with East."

By making a triangle rectangle, we can find the x and y components for this motion.

Y-component = 50m*cos(30°) = 43.3m

X-component = 50m*sin(30°) = 25m

Then the new position will be:

(40m, 30m) + (43.3m, 25m) = (83.3m, 55m)

Now we want to find the total displacement, this will be equal to the distance between the final position and the initial position.

The distance between two points (ax, ay) and (bx, by) is:

D = √( (ax - bx)^2 + (ay - by)^2)

In this case we want to find the distance between the points (83.3m, 55m) and (0, 0), this will be:

D = √( (83.3m - 0)^2 + (55m - 0)^2) = 99.82 m

The displacement is 99.82 meters.
