Wha happens to the weight of astronauts when they are in orbit

Physics
2 answers:
Lynna [10]3 years ago

That depends on the size of the orbit.  

In "low Earth orbit", like the Mercury, Gemini, early Apollo flights, and aboard the ISS, the astronauts' weight is about 85% of their weight when they're standing on the Earth's surface.  

BUT ... since everything in orbit is in "free fall", they don't <em>feel </em>the weight of their own body or anything else.  The feeling is like being completely without any weight.

Microgravity. It is sometimes called zero- gravity, but this is wrong. What happens is they go into free fall. On earth, gravity causes all things to fall, it can essentially be called a 'vacuum' if you will. So, I'm not to sure about it, but that's kind of what happens.

A). very large
B). very small
These are both wishy-washy words ... words that mean different things
to different people, and may even mean different things to the same person
at different times.
Even if everybody agreed on the meaning of these words, we wouldn't
have any idea which one may apply to the rover, because there's nothing
in the picture that gives any size reference !  We don't know from the picture
whether this thing is the size of a school book or a school bus.  Or somewhere
in between.

C). very mathematical
What in the world does this mean ? ?
I don't see a single number or math symbol anywhere in the drawing.
I don't think this is the correct choice.

D). very complex
In the drawing, there are thirteen different labels of things,
and eight of them have such long names that only their initials
are shown.
This is one complicated combination of many different machines.
I think this is the best choice of description.

Why does the moon exert a greater tidal influence than the sun?
andreyandreev [35.5K]
Well, I'm not sure right now that it actually does.

But if it does, that's because the sun is about 400 times
FARTHER from the Earth than the moon is.

What does a worm and wheel mechanism do to torque and speed​
sergejj [24]

Answer:Explanation:

Image result for what does a worm and wheel mechanism do to torque and speed​

Like other gear arrangements, a worm drive can reduce rotational speed or transmit higher torque. ... Each full 360 degree turn of a single start worm advances the gear by one tooth. For a multi start worm the gear reduction equals the number of teeth on the gear divided by the number of starts on the worm.

If the distance between two asteroids is halved, the gravitational force they exert on each other will
mamaluj [8]

Answer:

e) Be four times greater

Explanation:

Here we have to use Newton's gravitational law that relates the gravitational force between two objects with their masses (m_{1} & m_{2}) and the distance between them (r) in the next way:

F=G\frac{m_{1}m_{2}}{r^{2}} (2)

Now if distance between asteroids is halved:

F_{2}=G\frac{m_{1}m_{2}}{(\frac{r}{2})^{2}}

F_{2}=G\frac{m_{1}m_{2}}{\frac{r^{2}}{4}}

F_{2}=G\frac{4m_{1}m_{2}}{r^{2}}=4G\frac{m_{1}m_{2}}{r^{2}}

Note that G\frac{m_{1}m_{2}}{r^{2}} because (1) is F so:

F_{2}=4F

It's four times greater!
