<u>Answer:</u> The correct answer

For 1: Gamma rays

For 2: Alpha particle

For 3: Beta particle

<u>Explanation:</u>

Gamma rays are the rays which are emitted when an unstable nuclei undergoes a spontaneous electromagnetic process known as gamma ray emission. This process is a decaying process. These rays have very high energy.

Alpha particle are the particles which are released when a radioactive isotope undergoes alpha decay process and changes the nucleus of the parent atom. This particle carrying a mass of +4 units and has a charge of +2.

Beta particle is a particle which is released when a radioactive isotope undergoes a beta decay process. The particle released carry -1 charge and another name for this particle is an electron.

Hence, the correct answer for Statement 1 is gamma ray, Statement 2 is alpha particle and Statement 3 is beta particle.

Which statement is correct? (2 points)

Lemur [1.5K]

Answer:

When a neutral atom looses an electron to another neutral atom, two charged atoms are created.

Explanation:

On the off chance that one of the two unbiased particle looses an electron, it turns out to be emphatically (charge: +1), in light of the fact that the electron conveys a charge of - 1. Thus, the other atom which acknowledges the electron turns out to be adversely charged (charge: - 1). And in the end, we will have two charged atoms.

Someone help me with letter d. and e. I’m supposed to solve for y.

Bumek [7]

Answer:

$t=\frac{a}{\sqrt{1-\frac{y^2}{c^2}}}\\\frac{y^2}{c^2}=1-\frac{a^2}{t^2}\\y^2=\frac{c^2t^2-c^2a^2}{t^2}\\y=\frac{c}{t}\sqrt{t^2-a^2}$

$t=\frac{a}{\sqrt{1-\frac{v^2}{y^2}}}\\\frac{v^2}{y^2}=1-\frac{a^2}{t^2}\\\\\frac{v^2}{y^2}=\frac{t^2-a^2}{t^2}\\y^2=\frac{v^2t^2}{t^2-a^2}\\y=\frac{vt}{\sqrt{t^2-a^2}}$
