<span>The hypothetical scenario that would result in the moon not having different phases would be t</span>he moon always stays in one position relative to the earth and sun. Why? If the moon didn't have an phases it would stay in one position. Phases mean change, and if you observe the moon every night, you'll see how it changes; it repeats, so thus it's a pattern. 

So, your correct answer should be: <span>D.The moon always stays in one position relative to the earth and sun.</span>

HACTEHA [7]

Coquina rock is deposited on the water bodies of the Earth's surface and oceans.

<u>Explanation:</u>

Coquina is nothing but a type of sedimentary rock generally limestone that is formed by the chunks of shells, trilobites, brachiopods, or other invertebrates.

Coquina is deposited on the oceans and water bodies of the Earth's surface. Coquina looks like a soft white rock; therefore it can be used in construction of buildings.

if i release one steel ball from the top of a ramp and the other ball from the 40cm mark will they have the same acceleration?
solniwko [45]

Answer:

Yes, they will also have the same acceleration. Acceleration is controlled by the amount of weight (def. amount of gravitational pull on a given object) that the ball has. For one ball to accelerate quicker than the other, it would need a propulsion element, which it does not.

A block of mass m1 = 290 g is at rest on a plane that makes an angle θ = 30° above the horizontal. The coefficient of kinetic fr
GrogVix [38]

Answer:

The speed of the block when is fallen 30cm

v=0.726\frac{m}{s}

Explanation:

∑F= (m2)g - ƒ - (m1)g*sin(θ) = (m1)a

g = 9.81 m/s²

ƒ  = μN = μ(m1)g

(m2)*g - u*(m1)*g - (m1)*g*sin(\alpha ) = (m1)*a

(0.200)(9.81) - (0.1)(0.290)(9.81) - (0.290)(9.81)sin(30°) = (0.290)a

(0.200kg)(9.81\frac{m}{s^{2}}) - (0.1)(0.290kg)(9.81\frac{m}{s^{2}}) - (0.290kg)(9.81\frac{m}{s^{2}})sin(30°) = (0.290kg)*a

0.511101=0.29*a\\a=0.879\frac{m}{s^{2} }

v_{f}^{2}=v_{o}^{2}+2*a(x_{f}^{2}-v_{o}^{2})\\v_{o}=0\\v_{o}=0\\v_{f}^{2}=2*a(x_{f})\\v_{f}=\sqrt{2*a(x_{f})}\\v_{f}=\sqrt{2*0.879\frac{m}{s^{2}}*0.30m} \\v_{f}=0.726 \frac{m}{s}
