An atom in the ground state has a collision with an electron, then emits a photon with a wavelength of 1240 nm. What conclusion
anyanavicka [17]

Answer:

attached below is the free body diagram of the missing  illustration

Initial kinetic energy of the electron = 3 eV

Explanation:

The conclusion that can be drawn about the kinetic energy of the electron is

E_{e} = E_{3}  - E_{1}

E_{e} = initial kinetic energy of the electron

E_{1} = -4 eV

E_{3} = -1 eV

insert the values into the equation above

E_{e} = -1 -(-4)  eV

   = -1 + 4 = 3 eV

A severe thunderstorm dumped 2.4 in of rain in 30 min on a town of area 29 km2. What mass of water fell on the town? One cubic m
Alexus [3.1K]

Answer:

The mass of water is 1.7661\times10^{9}\ kg

Explanation:

Given that,

Area of town = 29 km²

Time = 30 min

Height = 2.4 inch

Mass = 103 kg

We know that,

1 m = 39.37 inch

So, 2.4\ inch =\dfrac{2.4}{39.37}

2.4\ inch=0.0609\ m

We need to calculate the volume

Using formula of volume

V=H\times A

Put the value into the formula

V=0.0609\times29\times1000^2

V=1766100\ m^3

We need to calculate the mass of water

Using formula of density

\rho=\dfrac{m}{V}

Put the value into the formula

1000=\dfrac{m}{1766100}

m=1000\times1766100

m=1.7661\times10^{9}\ kg

Hence, The mass of water is 1.7661\times10^{9}\ kg
