Halitic rocks have a large mineral layer of evaporite sedimentary rock, which is produced from drained lakes, playa and closed seas.

The difference between Halit rock layers and other rock layers is the element in it. The element in the Halit rock layer is sodium chloride.

<h2>Further explanation </h2>

Halit Rock Layer is a type of salt, a mineral form (natural) from sodium chloride (NaCl) or better known as rock salt.

Knowledge about the layers of soil and rocks on the surface of the earth is stratigraphy. Stratigraphy is the study of the history, composition and relative age and distribution of bedding layers and the interpretation of rock layers to explain the history of the Earth.

Answer:

Rock layer H is an igneous intrusion. It goes through layer E and all the layers beneath it, except layer J. So, layer H formed after layer E started to form and is younger than all the layers beneath it, with one exception. Igneous intrusion J cuts through layer H, so layer J is younger than layer H. Because the intrusion does not go through layer G, it formed before layer G. From the drawing, it can’t be determined whether layer H is older or younger than layer A.

A 12,500 N alien UFO is hovering about the surface of Earth. At time , its position can be given as () = ((0.24 m/s^3)^3 + 25 m)
stepladder [879]

a) F=(3675i-4543k)N

b) 5843 N

Explanation:

a)

The position of the UFO at time t is given by the vector:

r(t)=(0.24t^3+25)i+(4.2t)j+(-0.43t^3+0.8t^2)k

Therefore it has 3 components:

r_x=0.24t^3+25\\r_y=4.2t\\r_z=-0.43t^3+0.8t^2

We start by finding the velocity of the UFO, which is given by the derivative of the position:

v_x=r'_x=\frac{d}{dt}(0.24t^3+25)=3\cdot 0.24t^2=0.72t^2\\v_y=r'_y=\frac{d}{dt}(4.2t)=4.2\\v_x=r'_z=\frac{d}{dt}(-0.43t^3+0.8t^2)=-1.29t^2+1.6t

And then, by differentiating again, we find the acceleration:

a_x=v'_x=\frac{d}{dt}(0.72t^2)=1.44t\\a_y=v'_y=\frac{d}{dt}(4.2)=0\\a_z=v'_z=\frac{d}{dt}(-1.29t^2+1.6t)=-2.58t+1.6

The weight of the UFO is W = 12,500 N, so its mass is:

m=\frac{W}{g}=\frac{12500}{9.8}=1276 kg

Therefore, the components of the force on the UFO are given by Newton's second law:

F=ma

So, Substituting t = 2 s, we find:

F_x=ma_x=(1276)(1.44t)=(1276)(1.44)(2)=3675 N\\F_y=ma_y=0\\F_z=ma_z=(1276)(-2.58t+1.6)=(1276)(-2.58(2)+1.6)=-4543 N

So the net force on the UFO at t = 2 s is

F=(3675i-4543k)N

b)

The magnitude of a 3-dimensional vector is given by

|v|=\sqrt{v_x^2+v_y^2+v_z^2}

where

v_x,v_y,v_z are the three components of the vector

In this problem, the three components of the net force are:

F_x=3675 N\\F_y=0\\F_z=-4543 N

Therefore, substituting into the equation, we find the magnitude of the net force:

|F|=\sqrt{3675^2+0^2+(-4543)^2}=5843 N

Genrish500 [490]
<span>The correct answer is C. divergent plate. That's because the plates diverged, that is, they separated. When they moved away from each other, the sea filled the hole. The opposite would be convergent if two plates moved towards each other and squished out a sea. Transform would be if it changed from one form to another.</span>

If two swimmers compete in a race, does the faster swimmer develop more power?
valkas [14]
Power is equal to energy per unit time. In this case, power is proportional to energy while is inversely proportional to time,on the other hand. Given the two swimmers exerts same amount of energy but the faster swimmer just does things in faster time, then the faster swimmer should develop more power from shorter time

What is needed to set a body in motion
kumpel [21]

Answer:

Newtons law

Explanation:

According to this law, a body at rest tends to stay at rest, and a body in motion tends to stay in motion, unless acted on by a net external force.
