# When an alpha particle is emitted the atomic increases by what?

The emission of an alpha particle (which is a Helium nucleus) from a radioactive nuclide would decrease its atomic number (z) by two, and its mass number by 4. So for example, Plutonium-239 (z=94) would emit the alpha particle and jump back down the table to Uranium-235 (z=92). It is possible to go up the table (increase atomic number) through certain beta decays.

# How is the density at a compression in a compressional wave like the height of a transverse wave?

The amount of compression of a compression wave is like the amplitude of a transverse wave.

# What type of nuclear radiation is emitted in Boron 12 to Carbon 2?

Boron-12 (12B) typically undergoes beta decay, where a neutron is converted into a proton, emitting an electron (beta particle) and an antineutrino. This transformation results in carbon-12 (12C). So, the nuclear radiation emitted in this process is a beta particle.

# When U-238 decays to th-234 what has been emitted?

When U-238 decays to Th-234, an alpha particle is emitted. An alpha particle consists of two protons and two neutrons, and is essentially a helium nucleus.

# What is neutron proton scattering?

Neutron-proton scattering refers to the interaction between a neutron and a proton. It involves the exchange of a virtual meson between the two particles, which allows them to interact through the strong nuclear force. Studying neutron-proton scattering can provide valuable information about the structure and interactions of the atomic nucleus.

# If you were to have 80 grams of uranium how many grams would be present at the end of the second half time?

After the second half-life of uranium, half of the original amount will remain. Therefore, if you start with 80 grams of uranium, after one half-life you would have 40 grams remaining, and after the second half-life, you would have 20 grams.

# What is the half-life of a 200.0g sample of nitrogen-16 that decays to 12.5g of nitrogen-16 in 48s?

To find the half-life, we need to determine the time it takes for half of the sample to decay. In this case, the initial mass is 200.0g and the final mass is 12.5g. Starting with 200.0g, after one half-life it would be reduced to 100.0g. After two half-lives, it would be reduced to 50.0g. Since it took 48s to go from 200.0g to 12.5g, we can estimate that it would take approximately 96s (2 half-lives) for the sample to go from 200.0g to 50.0g. Therefore, the half-life is approximately 48s.

# What particles have very weak penetrating power?

Alpha particles have very weak penetrating power. They are heavy and charged, so they interact strongly with matter, causing ionization and losing energy quickly. Therefore, alpha particles can generally only travel a few centimeters in air and can be easily stopped by a sheet of paper or skin.

# Why does gamma radiation NOT change the type of atom?

Gamma radiation, which is a type of electromagnetic radiation, does not change the type of atom because it does not involve the transfer or exchange of particles. Unlike alpha and beta radiation, which involve the emission of particles from the nucleus, gamma radiation consists of high-energy photons that are released from the atomic nucleus. Therefore, it does not alter the composition or identity of the atom.

# Cyclotrons and synchrotrons accelerate charged particles by repeatedly supplying them with the pulses of?

electromagnetic fields. These fields are generated by powerful magnets which create a strong magnetic field. The particles are then guided in circular paths, and as they pass through the electromagnetic field pulses, they gain energy and accelerate. This process is repeated multiple times to achieve the desired energy for the particles.

# Why is density of water more in deep water?

The density of water increases with depth due to the increase in pressure. As water molecules are packed closer together under high pressure, the density of water increases. Therefore, in deep water where the pressure is higher, the density of water is also higher.

# Can you board a plane with a geiger counter?

Yes, you can typically bring a geiger counter on a plane as part of your carry-on luggage. However, it's always a good idea to check with the specific airline and airport security guidelines to ensure they allow it and to understand any specific regulations or restrictions that may apply.

# What makes up an alpha particle and how powerful is it?

An alpha particle consists of two protons and two neutrons, which is essentially the nucleus of a helium atom. It is relatively powerful due to its high kinetic energy and its large mass compared to other types of radiation. It can penetrate only a few centimeters in air and is stopped by a piece of paper or a few centimeters of human skin. However, it can cause significant damage if it enters the body through inhalation or ingestion.

# What is uniformly accelerated motion?

It means that acceleration is constant.

This meaning that velocity is varying with respect to time, we see this by this formula (v - v(initial) ) / t (Time).

# What is an example for a force causing an object to start moving?

The force you apply to the mouse button to make it click is.

# What does beta stand for?

Answer to the questionBeta doesn't stand for anything. Each major version of a product usually goes through a stage when new features are added (alpha stage), then a stage when it is actively debugged (beta stage), and finally a stage when all important bugs have been removed (stable stage).

# What is attenuation mean?

A reduction in the strength of a signal, the flow of current, flux, or other energy in an electronic system.

# How do you use electromagnets in medicine?

MRI (Magnetic Resonance Imaging) is widely used in modern medicine to image the body's internal structures in high contrast.

One new and still very experimental use is Transcranial Magnetic Stimulation: the stimulation of specific areas of the brain through electromagnetic induction. Repeated sessions have shown improvement in disorders such as depression and Parkinson's Disease. Altered states of consciousness, out of body states and religious experiences have been reported by human subjects.

# How is gamma radiation used in medicine?

gamma radiation is used in cancer treatment. the most common source of gamma radiation is.

# How dangerous is the threat of Water contamination from Nuclear waste?

If you put nuclear waste in a situation where groundwater can flow over it on the way to a water course, you will obviously get contamination. Nuclear waste stores have to be very carefully considered to find locations that are safe from water access.

# Has the Higgs boson been found yet?

We are not sure if the theorized Higgs boson is real or not. If it is, it would be provide some support to ideas about what mass (and, therefore, gravity, which is associated mass) really is. We're still looking for experimental support that the Higgs boson is real, and now that the Large Hadron Collider is up and running, all (interested) eyes are on CERN and awaiting results.

# How is nuclear power dangerous?

Nuclear energy as it is used to generate power can be dangerous. The nuclear reactors used to heat water to generate steam to spin turbines to generate electricity must be operated by individuals who know what they are doing. If something goes wrong, the duty crew must make all the right decisions and make them first time, every time. Failure to do so can cause structural elements of the core to fail and release both nuclear fuel and waste into the coolant passages in the core. (The fuel rods are designed to hold everything inside throughout the life of the fuel bundle.) This is what happened at Three Mile Island. Both mechanical failure and the failure of the duty crew to react correctly caused a meltdown. Spent fuel presents its own special problems. Fuel bundles must be recovered from the reactor and taken away and stored for an extremely long period of time before radiation levels are low enough to try to do anything with them. Fission byproducts are highly radioactive, and remain so for tens of thousands of years. Links are provided for further reading.

# Is there a positron in the nucleus of an atom?

There are no positrons in the nucleus of any atom. Positrons are anti-electrons; they are antimatter. They could be said to be the antimatter equivalent of the electron, and, as such, they would be present around the nucleus of an antimatter atom as the electrons are present around the nucleus of a "regular" atom.

Positrons can be produced in atomic nuclei by some kinds of radioactive decay, and they can be observed to be leaving a nuclear reaction called beta plus decay. But the positron leaves the nucleus of an atom as soon as it is created. It does not (cannot) exist in the nucleus of an atom.

# Do electrons have the mass as protons?

Protons are part of the nucleus, so they have less mass than the nucleus (except in the specific case of hydrogen, where the nucleus is a single proton so they have the same mass).

Electrons are much less massive than protons. It would take 1836 electrons to equal the mass of one proton.

Neutrons are very slightly more massive than protons, by just about the mass of an electron. They're close enough that they're generally treated as having essentially the same mass.
