<span>Its the impact theory.
It suggests that the moon resulted from the collision of two protoplanets, or embryonic worlds. One of those was the just-forming Earth, and the other was a Mars-size object called Theia. The moon then coalesced from the debris, thus giving it its irregular shape.</span>

A brave child decides to grab onto an already spinning merry‑go‑round. The child is initially at rest and has a mass of 34.5 kg.
rodikova [14]

Answer:

the moment of inertia of the merry go round is 38.04 kg.m²

Explanation:

We are given;

Initial angular velocity; ω_1 = 37 rpm

Final angular velocity; ω_2 = 19 rpm

mass of child; m = 15.5 kg

distance from the centre; r = 1.55 m

Now, let the moment of inertia of the merry go round be I.

Using the principle of conservation of angular momentum, we have;

I_1 = I_2

Thus,

Iω_1 = I'ω_2

where I' is the moment of inertia of the merry go round and child which is given as I' = mr²

Thus,

I x 37 = ( I + mr²)19

37I = ( I + (15.5 x 1.55²))19

37I = 19I + 684.7125

37I - 19 I = 684.7125

18I = 684.7125

I = 684.7125/18

I = 38.04 kg.m²

Thus, the moment of inertia of the merry go round is 38.04 kg.m²

If one sound wave has twice the amplitude of another the first sound is​
aleksley [76]

Answer:

if one wave has a negative displacement, the displacements would be opposite each other, so the displacement where the waves overlap is less than it would be due to either of the waves separately.

-causes a moment where the net displacement of the medium is zero. energy of waves hasn't vanished, but it is in the form of the kinetic energy of the medium

-then both emerge unchanged

point y is in the interior of xwz. given that and are opposite rays and mxwy​4(m​ywz), what is m​ywz?
Xelga [282]

point y is in the interior of xwz. given that and are opposite rays and mxwy​4(m​ywz), m​ywz = 36°

Opposite rays:- Opposite rays are the rays, which shares a common initial point, but points towards opposite directions. Angle between two opposite rays is 180°.

According to the question,

m∠XWY = 4(m∠YWZ) (Given)

As the two rays WX and WZ are opposite rays, the initial points of those are same. Here in the question, it is W.

∴∠XWZ = 180°

∴m∠XWY + m∠YWZ = 180°

⇒ 4(m∠YWZ) + m∠YWZ = 180°

⇒ 5(m∠YWZ) = 180°

⇒ m∠YWZ = 180°/5

⇒ m∠YWZ = 36°

Thus we can conclude that, m∠YWZ = 36°.
