The following statement best describes how gravity helps protoplanets create layers in that gravity pulls materials and generates compaction, which produces heat and causes materials to melt, sink, and rise. Option A is correct.
<h3>What is gravity?</h3><h3 />
Gravitation is a natural law by which all things with all matter are attracted towards one another. gravity causes weight to all matter and the gravity of the moon causes the ocean tides.
The force that draws massed bodies toward one another is known as gravity. Gravitatithus
According to the alternatives, gravity pulls things together and causes compaction, which generates heat and causes things to melt,
Thus, we may draw the conclusion that gravity draws materials and creates compaction, which generates heat and causes materials to melt, sink, and rise.
Hence option A is correct,

Answer:
Correct answer: vₓ = 30V , i₀ = 5A
Explanation:
You first calculate the equivalent resistance of the parallel connection of two resistances of 12 and 6 ohms.
1/ Re₁ = 1/12 + 1/6 = (12 + 6) / (12 · 6) => 1/Re₁ = 18/72 => 1/Re₁ = 1/4 =>
Re₁ = 4Ω
then you calculate the equivalent resistance of a series connection of two resistances of 8 and Re₁ = 4Ω
Re₂ = Re₁ + 8 = 4 + 8 = 12Ω
then you calculate the electric current according to Oh's law
i₀ = vc / Re₂ = 60 / 12 = 5A
at the end you calculate the voltage drop vₓ on the resistor of 6Ω
vₓ = i₀ · 6Ω = 5A · 6Ω = 30V

Answer:
speed of the Jon visiting parents = 56 mph
speed of the Jon when returning from home = 56 - 14 = 42 mph
Explanation:
given,
distance of Jon parent's house = 648 mile
avg speed when he was visiting his parent's house be 'x' mph
avg speed when he is returning from his parent's house be 'x-14' mph
total time taken = 27 hours
total distance = speed × time
648 = x × t₁
648 = ( x - 14 ) × t₂
t = t₁ + t₂
x² - 62 x + 336 = 0
x² - 56 x - 6 x + 336 = 0
(x - 56 )(x - 6)=0
on solving
x = 56 ,6
hence, speed of the Jon visiting parents = 56 mph
speed of the Jon when returning from home = 56 - 14 = 42 mph
