Sample Response:
Explanation:
The root beer exerts a force on all sides of the ice cream. These forces are all equal and cancel each other out. Gravity pushes downward on the ice cream. This can also be called the weight of the ice cream. Buoyant force pushes the ice cream upward. The ice cream floats because the buoyant force is greater than the weight of the ice cream.

Answer
Correct Answer is B(Edwin Hubble)
Explantion
The work of Subrahmanyan Chandrasekhar is likely to have been most influenced by Edwin Hubble because both have worked in the feild of astrophysics.
Subrahmanyan Chandrasekhar was an astrophysicist. He belons to India. He is known for his work on the theoretical structure and evolution of stars. Subrahmanyan Chandrasekhar with William Fowler won the Nobel Prize in Physics in 1983 largely for this early work. He has worked in many other areas within theoretical physics and astrophysics.
Edwin Hubble was an astronomer who belongs to America. He is known for Hubble Law. Hubble discovered that many objects which was thought to be clouds of dust and gas were actually galaxies beyond the Milky Way. He has an important contribution in establishing the fields of observational cosmology and extra galactic astronomy
Mechanical waves, it needs a certain medium to travel through. This medium can be a solid, liquid and gas. There are three types of mechanical waves namely, sound wave, water, and waves through the ropes.
A longitudinal wave is a wave that vibrates in a parallel direction with the motion. Also known as a compression wave. Both mechanical and longitudinal waves produce a sound.
When ALL the forces are equal, or in general when <span>forces in the opposite direction are equal
so we can have newton example:
10 newtons X -10 newtons
netforce = 0 newtons</span>
Melting ice is not a chemical reaction, but is a physical change. There is no chemical reaction involved during the melting process, and it is still the same molecular substance.
