What is meant by the following statement? "Inertia is directly proportional to mass." Inertia and mass are the same thing. Inertia and mass are the same size. Inertia increases as mass decreases. Inertia increases as mass increases.

Answers

Answer 1
Answer:

Inertia increases as mass increases.

Explanation:

Inertia is the resistance of an object to any change in motion. Inertia is proportional the mass of the object: in fact, as we experience in common situations, the larger the mass of an object, the more difficult it is to change its motion.

A simple example: while it is quite easy to stop a tennis ball thrown towards us, we know that it is not so easy to stop a large truck travelling towards us with the same speed: the reason for that is that the truck has much more mass than the tennis ball, so it has much more inertia. Therefore, inertia increases as mass increases.
Answer 2
Answer: inertia increases as mass increases. In fact, mass is what causes inertia

Physics is as good a place as any, I guess.

And, before we roll up our sleeves, may I also note that assigning 48 fill-ins
(4 each for 12 problems) is exceeded in its excess only by expecting all of
the answers in return for 5 points.    I'll give you the tips and hints you need
in order to solve these, and then I'll wish you well.

I see from the label in the upper corner that all of this refers to series circuits.
That's important to know, and I was about to ask.  So we're going to assume
that for the whole bunch on the page, R1 and R2 are in series, connected
across VS, and there are no other components involved besides the two
resistors.

OK.  Here are the tools you need:

On a resistor . . .
                             ' K ' = 'thousand'
                         ' Meg ' = 'million'

Total resistance . . . RT = R1 + R2 ohms

Voltage across each resistor:
                                                  VR1 = VS  [ R1 / (R1+R2) ]    volts

                                                  VR2 = VS [ R2 / (R1+R2) ]     volts

Total current in the series circuit:   
                                                   IT = VS / RT  = VS / (R1+R2)  Amps

And that's it. Easier than I thought.  There are some other things that
it could have asked for, but it didn't.

Example: 
Line #4:
VS = 5 volts
R1 = 470 ohms
R2 = 1,000 ohms

RT = R1 + R2 = 1,470 ohms

VR1 = VS ( R1/RT ) = 5 (470 / 1,470) = 1.598... volts
VR2 = VS ( R2/RT ) = 5 (1,000 / 1,470) = 3.401 volts

(Notice that  VR1 + VR2 always = VS.)

IT = VS / RT = 5 / 1,470 = 0.0034 Amperes = 3.4 mA (milliamps)

The power supplied by the battery is  (VS)²/RT = 0.017 watt ,
but it doesn't ask for that.

And that's it !  That's everything you need.  Go get 'em, champ !

Which part of a scientific argument must be supported by valid data? claim evidence reasoning theory

Answers

This question is a bit ambiguous because all parts of a scientific argument must be supported by valid data. However, among the choices, the closest synonym to "valid data" would be evidence. Evidence is the body of facts or information that support  a given idea.

Answer: Theory

Explanation: A claim is an interpretation based on the results of a given experiment, you first observe, and interpret the information.

Evidence is the valid data itself.

The reasoning is the approach or the "logic path" you used to reach some theory or claim.

The theory is an interpretation of the natural world, that explains why and or how some things work.

If we want to support a theory, we need to have some valid data that supports, at least, part of it, so the right answer here is theory.

Notice that claim also needs to be supported for valid data, but in the case of the claim you first get the data and then make the claim, and in the theory, the work is done in the other order.

In any one material, all electromagnetic waves have the same speed. But of course, since they may be traveling up, down, left, right, or slanty, they don't all have the same velocity.
