Answer:
Explanation:
The most common type of igneous rock making up the Hawaiian island chain is Mafic rock. Furthermore, the most common type of Mafic rock is basalt.
A statement which describes the changes that occur in this sequence of events is: 2. matter is converted into energy and then energy is converted into matter.
<h3>What is the law of conservation of matter?</h3>
The law of conservation of matter (LOCOM) states that mass can neither be created nor destroyed in any chemical reaction.
Similarly, the energy possessed by a matter can neither be created nor destroyed, but it can only be converted from one energy form to another.
In this context, we can logically deduce that a statement which best describes the changes that occur in this sequence of events is that matter is converted into energy and subsequently, energy is converted into matter.

Answer:
v = 31.3 m / s
Explanation:
The law of the conservation of stable energy that if there are no frictional forces mechanical energy is conserved throughout the point.
Let's look for mechanical energy at two points, the highest where the body is at rest and the lowest where at the bottom of the plane
Highest point
Em₀ = U = m g y
Lowest point
= K = ½ m v²
As there is no friction, mechanical energy is conserved
Em₀ =
m g y = ½ m v²
v = √ 2 g y
Where we can use trigonometry to find and
sin 30 = y / L
y = L sin 30
Let's replace
v = RA (2 g L sin 30)
Let's calculate
v = RA (2 9.8 100.0 sin30)
v = 31.3 m / s
You always multiply the mass (kg) by the velocity at which the object is travelling (m/s) to get the momentum (kg m/s) thus: 30 × 5 = 150 kg m/s
