What does an alpha particle consist of?

Physics
1 answer:
Tamiku [17]3 years ago
7 0
An alpha particle is like a Helium atom. And Helium has an atomic number of 2 and mass number or 4.

Mass Number =4,
Atomic Number = 2, for a Neutral Atom, Atomic Number = Number of Proton = 2

Mass Number = Proton + Neutron.

4 = 2 + Neutron

Neutron = 4 -2 = 2

Hence alpha particle has 2 Protons and 2 Neutrons. Option C.

Explain each of the following phenomena and how they extend our understanding of genetics from the work done by Gregor Mendel an
Korolek [52]

Answer:

Incomplete Dominance: In this case, the 3rd different phenotype is created by the heterozygous(CwCr) (for example, pink)

Co-Dominance: the heterozygous is observed to show both the homozygous conditions (for example the blood type iAiB shows both A and B carbohydrates)

Multiple alleles: This is when a gene has over 2 alleles (i.e. blood has ia ib i)

Polygenic inheritance: This is when over two different gene leads to the expression of a trait.

Pleiotropy: This is the when a gene shows several effects on an organism.

Epistasis: This is when more than one gene have strong control on the  expression of a trait (for example, E/e allele creates pigments)

Sex-linkage: This refers to the genes found in sex chromosomes

Gene Linkage: These are the genes situated in a similar chromosome.

If the mass of each ball were the same, but the velocity of ball A were twice as much as ball B, what do you think would happen
Margaret [11]
Given momentum is conserved and is mv

if
mass is the same and va=2vb
then momentum is m(2vb + vb)

if collision is elastic (bounces off)
then m(2vb + vb) = m(vfa + vfb)
3vb = vfa + vfb
meaning final velocities would be different

if collision is inelastic (sticks together)
then m(2vb + vb) = (m+m)vf
meaning final velocity would be same

is this what you wanted?
