The answer to the question is: YES.
Remember that every description of motion depends on the observer's 'reference frame'. In other words, motion is always RELATIVE TO something. There's no such thing as 'real' motion that is the same to everybody who measures it.
-- In the reference frame of somebody parked in the rest area, (or a chicken waiting to cross the road), you are moving to the East at 100 km/hr.
-- In the reference frame of the other passengers on your bus, you are at rest.
-- In the reference frame of a car driving at 120 km/hr in the same direction as your bus, you are moving WEST (backwards) at 20 km/hr.
-- In the reference frame of a bird flying North at 100 km/hr, you are moving South-East at 141 km/hr.
These measurements are all true and correct in THEIR reference frame. The measurement depends on the observer's motion just as much as it depends on YOURS.
That's why, when you asked "Is my motion ..." this or is it that, I had to answer YES. It could be either one. It depends on who's doing the measuring.
Answer:
All the planets in the Solar System orbit the Sun. When planets orbit the Sun, they don’t move around in a perfect circle. They all follow an 'elliptical path', meaning it looks more like an oval.

I would help u but u cant see nothing because its to small but you can actually go on the website and search word puzzle and the name of it....it should be on the top of the paper...the website will give u the answers
Answer:
ωf' =5.16 rad/s
Explanation:
Given that
Initial angular speed ,ωi= 125 rev/min ( 1 rev/min = 0.10472 rad/s)
ωi=13.08 rad/s
The angular speed after 1 min ,ωf= 0.7 x 125 = 87.5 rev/min
ωf=9.1 rad/s
Lets angular acceleration =α
We know that
ωf = ωi + α t
Now by putting the values in the above equation we get
9.1 = 13.08 + α x 60 ( after 1 min ,t= 60 s)
α = -0.066 rad/s²
The angular speed after 2 min
ωf' = ωi + α t
ωf' =13.08 - 0.066 x 2 x 60 rad/s
ωf' =5.16 rad/s
Therefore the angular speed after 2 min will be 5.16 rad/s.
I cant read it, i could most likely help if i could read it.
