1.)AM 630 is a station where you can listen to sports. The frequency is 630 khz(or 630,000hz). What is the wavelength?? 2.) A popular radio station, NPR, transmits a signal that is has a wavelength of 3.38m. What is the frequency of this signal?? Remember that speed of light is 299,792,458 m.

Explanation:

(1) The given equation is :

2(x + 3)=5x + 6 - 3x

Solving LHS first.

2(x + 3) = 2x +6

Solving RHS

5x + 6 - 3x  = 2x+6

LHS = RHS

So, it is always true.

(2) The given equation is :

x - 3=2x - 3 - x

LHS = x - 3

Solving RHS

2x - 3 - x = x-3

LHS = RHS

So, it is always true.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
