Use the given relationship to calculate the ionization energy of a thallium atom, given that radiation of 58.4 nm produces elect
Elenna [48]

The ionization energy is 1  × 10^-18 J

<h3>What is ionization energy?</h3>

The ionization energy is the energy required to remove an electron from an atom.

We have the following information;

wavelength of the photon = 58.4 nm

Speed of the electron = 2310 × 10^3 m/s

Since;

hv = I + 1/2mv^2

v = c/λ

hc/λ =  I + 1/2mv^2

I = hc/λ  - 1/2mv^2

I = (6.6 × 10^-34 × 3 × 10^8/58.4 × 10^-9) - (1/2 × 9.11 × 10^-31 × (2310 × 10^3)^2)

I = 1  × 10^-18 J

If a helium balloon breaks loose, it rises into the atmosphere and at some point bursts. Why
Mashutka [201]

Answer:

Explanation:By the time, that the balloon got too high in the sky, the pressure inside the balloon will soon overcome the pressure outside, and the balloon's elasticity is not too strong to hold the air inside, that the Helium gas inside will successfully push out the walls of the balloon and so it bursts!

A graduated cylinder is filled with 60.0 ml of water. A cube, made of aluminum, is carefully dropped into the cylinder. Aluminum
katen-ka-za [31]

Answer:

65 ml

Explanation:

The aluminum will not float , so it will displace a volume of fluid equal to its volume.

 13.5 gm / 2.7 gm/ml = 5 ml

the new graduated cylinder measurement will be 60 + 5 = 65 ml

A stealth bomber is moving at 799km/h west and travels to a top velocity of 1,1325km/h west in 4.8 minutes.
maria [59]

Answer:

10.1 ms^-2

Explanation:

From;

v = u + at

v = final velocity

u = initial velocity

a= acceleration

t = time taken

To convert the velocity from Km/hr to m/s we us;

x * 1000/3600

Where x is the velocity in Km/hr

So;

799 * 1000/3600 = 221.9 m/s

11325 * 1000/3600 = 3145.8 m/s

4.8 minutes = 4.8 * 60 = 288 s

Applying the formula;

a= v - u/t

a = 3145.8 - 221.9/288

a = 10.1 ms^-2
