Answer from: martinezizzie

Alpha > beta>gamma

Explanation:

Comparing only the three common types of ionizing radiation, alpha particles have the greatest mass. Alpha particles have approximately four times the mass of a proton or neutron and approximately 8,000 times the mass of a beta particle.

Gamma radiation, unlike alpha or beta, does not consist of any particles, instead consisting of a photon of energy being emitted from an unstable nucleus. Having no mass or charge, gamma radiation can travel much farther through air than alpha or beta, losing (on average) half its energy for every 500 feet.

Answer from: xojade

$\boxed {\boxed {\sf Gamma, beta, alpha}}$

Explanation:

Alpha. beta, and gamma particles are all emitted from an unstable or radioactive nucleus during radioactive decay.

Alpha particles are essentially helium ions, made of 2 protons and 2 neutrons. It has an atomic mass of 4 atomic mass units.Beta particles are also known as electrons. They have masses of 1/1840 atomic mass units.Gamma particles are actually just rays or photons of electronegative energy emitted. They have no mass or a mass of 0 atomic mass units.

So, if we place the mass in increasing order (least to greatest), then it is gamma (0 amu), beta (1/1840 amu) and alpha (4 amu).

Answer from: Quest

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation: if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
