Answer:

Based on the passage, the article's claim is not true. Therefore, the answer is:

No, because radio waves have energies that are too low to fall in the ionizing range.

Explanation:

Radio waves are generally known as forms of non-ionizing radiation. This means that they do not have enough energy, unlike microwaves, to separate electrons from atoms or molecules, thereby ionizing them. They cannot cause electron displacement, as claimed in the article. Therefore, they cannot break chemical bonds, which can cause chemical reactions or DNA damage. As non-ionizing radiation, radio waves occur at lower frequencies in the electromagnetic spectrum.

Measuring the size of a specific object might include which of these SI units?

defon

D. Meter, Kilogram

Explanation:

There are certain units for the measurements things which are around us.
This is the SI units for the measurement of the size of the objects.
SI units are international unit systems, they are one who accepted around the world.
It is called the International System of Units, used to expresses the phenomenon happens around us in a scientific method
Here, the meter is the unit for Length in the International System of Units and Kilogram is to represent the mass of the object in SI units system.

What are the starting materials for nuclear fission

aliina [53]

In normal fission reactors, the fuel used to start the nuclear fission is Uranium-235.
Generally, fuel rods enriched with uranium-235 are used to start the fission. When a nucleus of uranium-235 absorbs a neutron, it becomes unstable and then it breaks apart, producing two smaller nuclei, several neutrons and energy. The additional neutrons produced in the reaction are then absorbed by other nuclei of uranium-235, triggering other fission reactions, and so on.

The electron gun in an old TV picture tube accelerates electrons between two parallel plates 1.0 cm apart with a 20 kV potential

Julli [10]

Answer:

A) electric field strength between the plates;E = 2 x 10^(6) N/C

B) exit velocity;v = 8.39 x 10^(7) m/s

Explanation:

We are given;

Potential difference; V = 20 kV = 20000 V

Distance between the 2 parallel plates; d = 1cm = 0.01 m

A) The electric field strength will be gotten from;

E = V/d

E = 20000/0.01

E = 2000000

E = 2 x 10^(6) N/C

B) For exit speed, we'll use the formula for Kinetic energy; KE = (1/2)mv²

KE is also expressed as; V•q_e

Thus,

(1/2)mv² = V•q_e

Where;

V is potential difference = 20000 V

Q_e is charge of electron which has a constant value of; (1.6 x 10^(-19))C

m is mass of electron with a constant value of (9.1 x 10^(-31)) kg

v is the velocity

Thus, making v the subject, we have;

v = √((2V•q_e)/m)

v = √((2 x 20000•(1.6 x 10^(-19)))/(9.1 x 10^(-31)))

v = 83862786 m/s or

v = 8.39 x 10^(7) m/s

mixas84 [53]

The role of thermal energy is to balance the electrical energy lost from the light bulb.

<h3>Energy conservation</h3>

The law of energy conservation states that energy can neither be created nor destroyed but can be transformed from one form to another.

<h3>Thermal energy</h3>

This is a form of energy that occurs due to rise in temperature.

The role of thermal energy is to balance the electrical energy lost from the light bulb.
