A theory is a framework of ideas and assumptions used to explain some set of observations and to make predictions about the real

world. Each of the three theories for the formation of the Moon lead to different predictions about evidence that we should find. Which of the following predictions should be true if each theory is correct? The theories of the Moon's formation make different predictions:
Coformation theory:

•The Moon and Earth should have very similar compositions.
•The Moon and Earth should have similar densities.

Capture theory:

•The Moon and Earth should have completely different compositions.
•Mathematical models should predict that the capture of a Moon-sized satellite would be likely in Earth's early history.

Impact theory:

•Earth and the Moon should have similar mantles and dissimilar cores.
•Computer simulations should predict that a collision between Earth and a Mars-sized object would produce a Moon-sized satellite with a stable orbit.

If any of the theories are true, their predictions should bear out in the actual evidence.

8 0

Answer:

All the predictions in the impact theory are true.

Explanation:

That’s because of their predictions. Modern computer simulations predict that there happened a collision between Earth and a planet named as Theia. The chunks of both planets conformed into a stable orbit and form the satellite that we know today as our Moon. Similarly, both moon and Earth share similar mantle compositions but cores are dissimilar in terms of their size and composition.

Why is the sky blue?
ladessa [460]

The sunlight of all colors passes through air, the blue part causes charged particles to oscillate faster than does the red part. More of the sunlight entering the atmosphere is blue than violet, however, and our eyes are somewhat more sensitive to blue light than to violet light, so the sky appears blue.

Suppose a spring has a relaxed length of 28.3 cm. The simulation refers to this as the natural length. This is the length of the
den301095 [7]

Answer:

Explanation:

Normal length of spring = 28.3 cm

stretched length of spring = 38.2 cm

length of extension = 38.2 - 28.3 = 9.9 cm

= 9.9 x 10⁻² m

force applied to stretch = .55 x 9.8 ( mg )

= 5.39 N

Force constant = force applied / extension

= 5.39 / 9.9 x 10⁻²

= .5444 x 10² N /m

= 54.44 N/m

Imagine that there is a small rocky body caught by Earth’s gravity. Draw a comic-strip cartoon
vladimir1956 [14]

To create this comic strip you can use a narration describing each step and illustrate each one with one image or drawing.

Creating a comic strip involves using images and short texts to explain a specific idea or phenomenon. In the case of the process for a meteor to enter Earth you can use the following ideas.

  • A meteoroid approaches the Earth at high speed and draw a meteor traveling near to different planets and approaching Earth.
  • What is that? and draw the Earth wondering who or what is approaching.
  • The meteoroid enters the atmosphere of the Earth and becomes a meteor and draw the rocky body burning
  • The rocky body crashes with the surface becoming a meteorite and draw the zone where the meteorite crashed.

A spherical gas-storage tank with an inside diameter of 9 m is being constructed to store gas under an internal pressure of 1.50
lutik1710 [3]

Answer: 33 mm

Explanation:

Given

Diameter of the tank, d = 9 m, so that, radius = d/2 = 9/2 = 4.5 m

Internal pressure of gas, P(i) = 1.5 MPa

Yield strength of steel, P(y) = 340 MPa

Factor of safety = 0.3

Allowable stress = 340 * 0.3 = 102 MPa

σ = pr / 2t, where

σ = allowable stress

p = internal pressure

r = radius of the tank

t = minimum wall thickness

t = pr / 2σ

t = 1.5*10^6 * 4.5 / 2 * 102*10^6

t = 0.033 m

t = 33 mm

The minimum thickness of the wall required is therefore, 33 mm
