Batteries (e.g., lead-acid batteries) store chemical energy and convert it to electric energy on demand. Batteries do not store

electric charge or charge carriers. Charge carriers (electrons) enter one terminal of the battery, acquire electrical potential energy, and exit from the other terminal at a lower voltage. Remember the electron has a negative charge! It is convenient to think of positive carriers flowing in the opposite direction, that is, conventional current, and exiting at a higher voltage. (Benjamin Franklin caused this mess!) For a battery rated at 12 V and 350 A-h, determine: a. The rated chemical energy stored in the battery. b. The total charge that can be supplied at the rated voltage.

Answer:

A battery is a device consisting of one or more electrochemical cells with external connections provided to power electrical devices such as flashlights, smartphones, and electric cars. When a battery is supplying electric power, its positive terminal is the .... Batteries convert chemical energy directly to electrical energy.

A proton is going 2,000 m/s into a magnetic field of 300 T. How much force does it feel. The charge of a proton = 1.602 x 10^-19
NemiM [27]
This depends on the direction of the velocity vector to the magnetic field vector. The force is F=q(VxB)  ("x" is the cross product.)  The max force is when V and B are perpendicular.  Then F=qVB = (1.602e-19)(2000)(300) = 9.612e-14 N

Which statement best describes insulators? Free electrons can move to other atoms Electrons within their atoms are strongly held
balandron [24]

Answer:

The statement that best describes insulators is <u><em>"Electrons within their atoms are strongly held by the nuclei"</em></u>

Explanation:

Atoms are constituted by a nucleus with positive charge (protons and neutrons), around which negative charges (electrons) revolve.

Substances that have a huge amount of "free electrons" that can move through the material are called conductors. This is due to the low resistance to the movement of the load or electric current.

Materials that do not conduct electricity are called insulators. In this case the electrons are strongly bound to the nucleus and cannot move freely. In this way a great resistance to the flow of electric current is offered.

Finally, semiconductors are the materials that can have electrical properties of conductors or insulators.

So<u><em> the statement that best describes insulators is "Electrons within their atoms are strongly held by the nuclei"</em></u>
