When did rock layer H form relative to the other rock layers? In your answers, compare layer H to as many rock layers as you can
AfilCa [17]

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.

At what altitude above the earth's surface would the acceleration due to gravity be 4.9 m/s^2? Assume the mean radius of the ear
Mandarinka [93]
We apply the gravity calculation expressed in the formula: g=GM/r2 
where G is the gravitational constant, m is the mass and r is the radius
r=√GM/g
(1)       Radius = √6.674e-11*5.972e24/8             = 7058 kms    Earth radius or surface of earth from center of earth= 6400 kmsSo r= 658 kms from surface of earth.
Gravity 8m/s2 will be at 658 kms from surface of earth.
(2) half gravity= 9.8/2= 4.9 m/s2     Radius=√6.674e-11*5.972e24/4.9                 = 9019 kms        Half Gravity will exist at 9019-6400= 2619 kms from surface of earth.

Add these two velocity vectors to find the magnitude of their resultant vector.
hammer [34]

The  magnitude of their resultant vector is 4.6 meters/seconds

Since we are to add the  velocity vectors in order to  find the magnitude of their resultant vector.

Hence:

Resultant vector magnitude=5.8 meters/seconds + (1.2 meters/seconds)

Resultant vector magnitude=5.8 meters/seconds-1.2 meters/seconds

Resultant vector magnitude 4.6 meters/seconds

Inconclusion The  magnitude of their resultant vector is 4.6 meters/seconds

according to newton's first law of motion what is the reason for a ball throwing up in the airfall back to earth
skelet666 [1.2K]
The force of earth's gravitational field is always directed downwards (towards the center of the earth. When the ball is thrown up, it is going against the earth's gravitational field and so, the earth's gravitational force pulls it back down, accelerating it downwards.
