Answer:
It's Helium.
Explanation:
The superficial layers of the star compress the core as an effect of its own gravity. Therefore, atoms will be closer to each other in the core, allowing them to be combined.
A nuclear reaction occurs when light elements combine into heavier elements (that is known as nucleosynthesis). Different ways in which that can happen exist, but the most common in the Sun, according to its mass, is the Proton-Proton chain reaction. In that fusion reaction two atoms of Hydrogen are combined to form Helium.
Remember that a Helium atom is composed of two Protons and two Neutrons.
The Proton-Proton chain works in the following way:
+ = 
+ 
+ 
Two Protons combine each other () and one Deuterium () is gotten, and one Neutrino (), and one Positron () are emitted from them.
+ = 
+ 
A deuterium and Proton combine each other and a Helium three nucleus() is gotten, and a gamma ray () is emitted.
+ = 
+ +
Two Helium three nucleus combine and a Helium atom () is gotten, and two Protons are emitted.
So, when hydrogen atoms fuse together helium is created.
We have that for the Question, it can be said that the amount by which the length of the stack decreases is
From the question we are told
A copper (<em>Young's modulus </em>1.1 x 1011 N/m2) cylinder and a brass (Young's modulus 9.0 x 1010 N/m2) cylinder are stacked end to end, as in the drawing. Each <em>cylinder </em>has a radius of 0.24 cm.
A compressive force of F = 7900 N is applied to the right end of the brass cylinder. Find the amount by which the length of the stack <em>decreases</em>.
Generally the equation for <em>copper </em>cylinder is mathematically given as
Generally the equation for brass<em> </em>cylinder is mathematically given as
Therefore Total change in length

Answer:
the study of geological factors and the ways the earth
The instant it was dropped, the ball had zero speed.
After falling for 1 second, its speed was 9.8 m/s straight down (gravity).
Its AVERAGE speed for that 1 second was (1/2) (0 + 9.8) = 4.9 m/s.
Falling for 1 second at an average speed of 4.9 m/s, is covered <em>4.9 meters</em>.
ANYTHING you drop does that, if air resistance doesn't hold it back.
Answer:
B. Dust storm
Explanation:
A meteorologist would predict dust storm most likely. Before dust storm the air condition and air pressure reduces in the particular area which indicate towards a dust storm. As pressure of a region reduces the air of the neighboring area try to maintain that pressure and rush towards low pressure area and causes dust storm.
