The correct one is gamma rays. Lets go over them one by one.

Gamma rays are rays that arise from gamma decay, a type of radioactive decay. Often, after another decay, the nucleus is still unstable and it gives off energy in the form of gamma rays to stabilize itself. Hence, gamma rays have nothing to do with the electron structure, only with the nucleus of the atom.

X-rays are the product of accelerating electrons, hence only specific atoms can emit a specific energy of X-rays; similarly for the photoelectric phenomenon, the energy which is needed for photoelectrons to be created depends on the electron structure of the atom (in both cases, it is important to see how strong the bond between electron and atom is).
Finally, spectral lines differ depending on the electron structure of the atoms since electrons with different energies absorb different frequencies of light.

matrenka [14]

Answer:

petroleum

Explanation:

Petroleum is a gas that we use that just goes into the air whilst water can be recycled and purified, wind never ever goes away, and solar power can be converted into energy.

Why does a mountain of uranium not explode as a bomb? ​
djyliett [7]

Answer:

“A mountain of uranium” is an indefinable amount of uranium. If it means uranium ore as found in nature, then the concentration of uranium is orders of magnitude too low for any type of reaction.

A bowling ball is far from uniform. Lightweight bowling balls are made of a relatively low-density core surrounded by a thin she
Leni [432]

Answer:

Part a)

I = 17.4 \times 10^{-3} kg m^2

Part b)

I = 14.9 \times 10^{-3} kg m^2

Explanation:

Part a)

Moment of inertia of the core of the ball

I_1 = \frac{2}{5}m_1r_1^2

I_1 = \frac{2}{5}(1.6)((\frac{0.196}{2})^2)

I_1 = 6.14 \times 10^{-3} kg m^2

now the moment of inertia for thin shell

I_2 = \frac{2}{3} m_2r_2^2

I_2 = \frac{2}{3}(1.6)((\frac{0.206}{2})^2)

I_2 = 11.3 \times 10^{-3} kg m^2

now total inertia of the ball is given as

I = I_1 + I_2

I = 17.4 \times 10^{-3} kg m^2

Part b)

Moment of inertia of uniform ball of mass 3.2 kg

I = \frac{2}{5} mr^2

I = \frac{2}{5}(3.2)((\frac{0.216}{2})^2)

I = 14.9 \times 10^{-3} kg m^2

When ionizing radiation strike atoms or molecules in their paths they cause _____
Brrunno [24]

Answer:

C) ions or free radicals, highly reactive species that can cause undesirable effects in living tissue.

Explanation:

Ionizing radiation is a type of energy released by atoms in the form of electromagnetic waves or particles

When a cell absorbs radiation, there are four possible effects on the cell.

• The cell may suffer enough damage to cause loss of proper function, and the cell will die.

• The cell may lose its ability to reproduce itself.

• The cell’s genetic code (i.e., the DNA) may be damaged such that future copies of the cell are altered, which may result in cancerous growth.

• The absorption of radiation by a cell may have no adverse effects.

The detrimental effects of ionizing radiation (IR) involve a highly orchestrated series of events that are amplified by endogenous signaling and culminating in oxidative damage to DNA, lipids, proteins, and many metabolites. Despite the global impact of IR, the molecular mechanisms underlying tissue damage reveal that many bio molecules are chemo selectively modified by IR

Hence the correct answer is C.
