your friend wants to know the amount of salt added to her favorite fast food French fries. what would you recommend that she do to find out the amount of salt ?

Answers

Every fast-food chain is required by law to make the nutrition content of the
items on its menu publicly available.

My friend should walk into her favorite place, or into the nearest McRonald's,
Bendy's, Tennessee Fried Turkey, Bulgur King, Plucky Please, White Palace,
Pita Hut, Carl's Senior, Back in the Box, or any of those others, ask to see
the Manager, and ask the manager for a chart of nutritional information that
includes their french fries.

To be nice about it, she should do this at a time when the place is not too busy,
and the manager doesn't have a lot of more-important things that need to be
doneright now.

Under the french fries, look at the serving size, and the figure for "Sodium"
in that serving, which is the nutrient that your body gets from salt. Less is
better. More is worse. For an adult, the CDC Institute of Medicine says
that 1500mg a day is 'adequate' for an adult. The US Food and Drug
Administration recommends that adults should get 'no more than' 2300mg
in a day. People who have high blood pressure are supposed to watch it,
and take in a lot less sodium.

And there are organizations with official-sounding names that totally dispute
all of this.

But to answer your question, that's what she should do to learn the amount
of salt used at the place where likes to get her french fries.

How do charges move through an insulated wire connected across a battery? Use the terms potential difference, current, conductor, and insulator in answer.

Answers

The battery has both a positive side and a negative side. The potential difference will be the potential of the positive end of the battery minus the potential of the negative end, which will result in positive potential, or power. This potential is what gives the electrons the ability to flow from the positive end to the negative end, or to make a current. While the outside of the insulated wire is the insulator, the inside of the wire has copper, which is the conductor of the current. So, this current will go through the copper of the wire (and not the insulator) from the positive side to the negative.

Answer:

Battery is the source of electrical energy which will help the charge to flow through a medium.

Battery is a constant source of potential difference which will create constant potential difference across the ends of a conductor where it is connected.

When a charge is passed through the constant potential difference then the change in electrostatic potential energy will give kinetic energy to the charge.

It is given as

$q\Delta V = (1)/(2)mv^2$

so here charge will continuously flow through the conductor across which potential difference is applied by the battery. This constant motion or flow of charge is known as electric current.

What is the minimum resistance which can be made using five resistors each of 1/5

Answers

The minimum resistance to the flow of electrical current is achieved when
the resistors are connected in parallel, just as the minimum resistance to the
flow of vehicular traffic is achieved when several lanes are built in parallel.

When 5 equal resistors are connected in parallel, the net resistance of their
combination is just 1/5 of the value of each one.

So 5 equal resistors in parallel, each with a resistance of 1/5 ohm, have a
combined net resistance 0f 1/25 ohm.
