What type of bond is formed if atoms donate electrons to other atoms when the elements are combined?

Answers

Ionic bond.

In the ionic bond one atom loses one or more electrons, leaving the atom with positive charge, and the other atom accepts those electrons standing with negative charge.

If the current in each wire is the same, which wire produces the strongest magnetic field?-a wire that is 1mm thick and not coiled
-a wire that is 2mm thick and not coiled
-a wire that is 1-mm thick and coiled
-a wire that is 2-mm thick and coiled

Answers

If the current in each wire is the same, the wire that produces the strongest magnetic field is a wire that is 2 mm thick and coiled. The correct option is d.

What is a magnetic field?

A magnetic field is a false field of current created. This interactive animation shows how the magnetic field relies on the direction of the current that creates the field and is strongest in the vicinity of the wire.

In every wire, the current is the same. If a wire carrying electricity is wound with additional turns, the magnetic field generated by the wire grows. Low resistance to the current would result from a thick wire. Therefore, the highest magnetic field would be produced by a 2-mmthick wire that is coiled.

Therefore, the correct option is d. a wire that is 2 mm thick and coiled.

Answer: option 4: A wire that is 2-mm thick and coiled.

Explanation:

The current in each wire is same. The magnetic field due to a current carrying wire increases if the wire is coiled with the more number of turns. A thick wire would cause low resistance to the current. Hence, a 2-mm thick wire which is coiled would produce the strongest magnetic field.

Thermal energy is added to a sample, its particles move ?

Answers

Yes, if the temperature increases, than that means the particles are moving faster. Temperature is the measure of movement of particles in an object or substance.

The ____ states that between 15 and 20 billion years ago, the universe began expanding out of an enormous explosion. A. H-R diagram
B. binary star theory
C. Big Bang theory
D. "big crunch" theory

Answers

In my opinion, the correct answer among the choices listed above is option C. The Big Bang Theory states that between 15 and 20 billion years ago, the universe began expanding out of an enormous explosion. However, the exact number is approximately 13.8 billion years ago.

Answer:

Big Bang theory

Explanation:

The big bang theory describes the beginning of the universe. According this theory, all the matter of the universe was confined at a point and about 15-20 billion years ago, it started expanding out of a huge explosion -the big bang. The universe has been expanding since then. The discovery of cosmic microwave background radiation provides the evidence to this theory.

Thus, the correct option is C.

When a wave is acted upon by an external damping force what happens to the energy of the waveA-the energy of the wave decreases gradually
B-rhe energy of the wave increases gradually
C-there is no change in the energy of the wave
D-the propagation of the wave stops immediately

Answers

Answer:

A-the energy of the wave decreases gradually

Explanation:

when a wave is acted upon by an external damping force the energy of the wave decreases gradually.

The energy degrades into the form of heat which is considered to be of less value and use. The reason is because it disperses and spreads more widely.

So therefore it end up as heat with a little sound but that is close to none because that too disperses into heat i.e. decreased form of energy.
