For the motion of a falling object, which graphs are straight lines? *

Acceleration versus time only
Displacement versus time only
O Displacement versus time and acceleration versus time
O Velocity versus time and acceleration versus time

Answers

Answer:

Displacement versus time and acceleration versus time

The graphs which shows the straight line for the motion of a falling object are velocity versus time and acceleration versus time.

What is a position-time graph?

The position-time graph shows the change in position of the moving object over the timescale.

Displacement-time graph-The displacement-time graph shows the position of the moving object over the timescale. This graph tell that how far the object is from its initial position over the timescale. Velocity-time graph-The velocity-time graph shows the speed of the moving object over the timescale. Acceleration-time graph-The velocity-time graph shows the change in speed of the moving object over the timescale.

In the image attached below, the graph is plotted for the Displacement-time graph (A), Velocity-time graph (B), and Acceleration-time graph (C).

In this three graph only velocity and acceleration shows the straight lines for the motion of falling object.

Hence, the graphs which shows the straight line for the motion of a falling object are velocity versus time and acceleration versus time.

How are bacteria different from other cells? 24 points and Brainliest for the first answer

Explanation:

Answer:

Bacterial cells are prokaryotic and cells of other organisms are eukaryotic cells. So, difference between eukaryotes and bacteria is that there is a membrane-bounded nucleus in eukaryotes and not in bacteria.

Why do you like trains

Answers

I like trains because I have always found trains utterly fascinating, passenger trains as well as freight trains, real trains as well as model trains and toy trains. I think it is because it is so fascinating to see this long string of cars obediently following behind the locomotive no matter how the track may twist and turn. And certainly I love riding them as well.

Which is more harmful a nuclear war or 1,000,000 comets heading straight towards the earth? explain lol

Answers

The comets aren't harmful at all, as long as they're still "heading ... towards the Earth".

But if you want to compare a nuclear war to a comet's IMPACT, then if the comet is big enough and fast enough, the impact of a SINGLE comet could be far more harmful than a nuclear war.

And "big enough" could be a rock only a few miles across.

A million uvum ? No question. The comets are, if they hit.

It depends. To be real, they both are harmful but it only depends on the size and impact zone of it. If comets are too large and very hard, then of course yes, it would be more harmful.
