Answer:
Vesicular texture refers to volcanic rocks that contain holes called vesicles that were formed by gas bubbles in lava. This igneous rock is called scoria. The vesicles form from escaping gas bubbles in cooling lava.
B. Main sequence
C. Nebula
D. Protostar
The correct answer is D. Protostar.
Nuclear fusion in a star's lifecycle begins during the protostar stage. This is when the temperature and pressure of the protostar ignite nuclear fusion, transitioning into a main sequence star.
In the life cycle of a star, nuclear fusion begins when the star has reached the protostar stage. The initial stage in the development of a star is the nebula, which is a cloud of dust and gas. Over time, the nebula's materials collapse under gravity to form a hot core known as a protostar.
When the protostar's temperature and pressure rises, it triggers nuclear fusion and the star begins turning hydrogen into helium.
This marks the transition from a protostar to a main sequence star, which is the stage of stable nuclear fusion.

Answer:
188.7 m
Explanation:
height of bridge above water (h) = 393 m
mass of bungee jumper (m) = 150 kg
length of cord (L) = 78 m
acceleration due to gravity (g) = 9.8 m/s
initial energy = mgh = 150 x 9.8 x 393 = 577,710 J
since the jumper barely touches the water, the maximum extension of the cord (x) = 393 - 78 = 315 m
from the conservation of energy mgh =
therefore
577,710 =
k = 11.64 N/m
from Hooke's law, force (f) = kx' ⇒ mg = kx'
where x' is the extension of the cord when it comes to rest
150 x 9.8 = 11.64 × x'
x' = 126.3 m
the final height at which the cord comes to a rest = height of the bridge - length of the cord - extension of the cord when it comes to rest
the final height at which the cord comes to a rest = 393 - 78 - 126.3 = 188.7 m
