A nuclear to thermal and radiant

Explanation:

Nuclear fission is the disintegration of the force that holds the nucleus of the atom together, creating two different but lighter nuclei.

In nuclear fission, it seeks to break the force of attraction or nuclear force that joins the protons and neutrons that form the nucleus of an atom. Neutrons without electric charge are used against the nucleus of the atom to produce enough excitation energy to deform the nucleus into two halves.

determine the longest wavelength of light required to remove an electron from a sample of potassium metal, if the binding energy
Dafna11 [192]

Answer:

The wavelength of light is 68 nm.

Explanation:

Given data:

Binding energy of electron = 176 × 10³ Kj/ mol or   (1.76× 10⁶ j/mol)

Wavelength of light require to remove the  electron = ?

Solution:

E = hc / λ

h = planck constant (6.63×10⁻³⁴ J/s)

c = speed of light = (3×10⁸ m/s)

The energy require per electron is

1.76 × 10⁶ j / 6.02× 10²³ = 2.92 × 10⁻¹⁸ J

Now we will put the values in formula,

E = hc / λ

λ =  hc / E

λ = 6.63×10⁻³⁴ m².kg.s⁻¹ . 3×10⁸ m/s / 2.92 × 10⁻¹⁸ J

λ = 19.89×10⁻²⁶ m /2.92 × 10⁻¹⁸   (m².kg.s⁻² = J)

λ = 6.8 ×10⁻⁸ m

λ = 6.8 ×10⁻⁸ × 10⁹

λ = 68 nm

A 20-kg bicycle carrying a 50-kg girl is traveling at a speed of 8 m/s. What is the kinetic energy of the girl
finlep [7]

Answer:

The answer to your question is Ke = 2240 J

Explanation:

Data

mass of the object = 20 kg

mass of the girl = 50 kg

speed = 8 m/s

Kinetic energy = Ke = ?

Formula

Ke = 1/2 mv²

Process

Kinetic energy is due to the movement of an object.

1.- Calculate the total mass

Total mass = 20 + 50 = 70 kg

2.- Substitution

Ke = 1/2(70)(8)²

3.- Simplification

Ke = 1/2(4480)

4.- Result

Ke = 2240 J

As part of a science experiment, Jose did a test for starch on a slice of apple and a slice of potato. The yellow-orange iodine
juin [17]

Answer:

See explanation

Explanation:

Iodine solution is used to test for starch.  A positive test for starch gives a blue-black color.

The fact that the color of the apple remained the same is indicative of the fact that starch was not contained in the apple.

A change in the color of potato indicates the presence of starch in the potato.

The fact that iodine did not react with apple should not be taken to mean that apples contain no starch at all. Starch changes gradually to sugar as fruits ripen. This is why the apple gave a negative test for starch.
