(a) $\mathrm{c}^{\mathrm{n}} \Gamma \mathrm{n}$ (b) $\mathrm{c}^{\mathrm{n}-1} \Gamma \mathrm{n}$ (c) $\frac{\Gamma n}{c^{n}}$ (d) $\frac{\Gamma n}{c^{n-1}}$

So we have alpha, beta and gamma particles. We also have a symbol mass char, mhm. Ionizing power and penetration. So for the first one symbol will be 4 to helium, two positive 42 alpha and 42 helium. The mass will be 6.65, Multiplied 10 rest upon negative 24 charges to positive penetration power is high. Oh sorry, ionizing power is high and the penetration power 0.03 millimeter. For the beta particle We'll have 0 -1 electrons zero negative one pito 9.11 10 days to find negative 28 Charge is -1 moderate organization. And And penetration will be 2 mm comma particles 00 comma mass 00 Low lionizing power and the highest penetration 10 cm.

There are many different types of radiation that come from a um unstable radioactive knew Clyde. The types of radiation have been abbreviated in a symbolic fashion. So each of these types of radiation have its own symbol. You were asked to determine whether or not the symbol provided corresponds to an alpha particle, beta particle, gamma ray, positron, neutron or proton. The first one is E with a superscript on the left hand side, zero, and a subscript negative one. On the left hand side. A beta particle corresponds to an electron with a one minus charge and no mass. So this means there is no mass. It has one minus charge and E stands for an electron. Therefore this would be a beta particle. The next one is N with a massive one and no charge and stands for a neutron. A neutron has a massive one and it does have no charge. So this would be a neutron. Then we have this gamma simple. There's no mass to a gamma ray and there's no charge to a gamma ray. So this symbol corresponds to a gamma ray.

Quickly in this question, we are asked to identify each of these particles and name them, so talk A represents a beta particle or an electron. This is also called an electron, and this is the same Wulfric a little e better zero for its mass number and negative one for its charge. And B represents a neutron with the letter and as its chemical symbol and one as its mass number and zero as its judge. C represents gamma radiation with the Greek symbol Gamma as its chemical symbol, zero as its mass number because it doesn't have a mass and zero as its charge because it is neutral.

This question asks us to write all the possible combinations that would result in a barrier on made up of ups downs or strange quirks. And the key idea here is that barry on is made up of three works and we're ignoring the anti Deloreans for now. So we can have an up Uh huh up pork. You could have a down down down and it's strange. Strange. Strange. You could have an up up down and then up up. Strange. Yeah. Okay. We could have an up down, down and then up. Strange. Strange. Okay, then we can have a down down strange and down. Strange. Strange. Yeah. And lastly, we can have Strange up down, sadly. This is 123456789, 10 possible combinations.
