Answer:
one dimension of motion on a circle is "back and forth"
Explanation:
Whether the position graphs look the same or not is a function of the acceleration (and velocity), and how position is measured.
For a circle centered at the origin, uniform motion around the circle will be equivalent to sinusoidal motion in the x- or y-directions. So, that motion is equivalent to sinusoidal motion "back and forth", however it may be generated.
The "back and forth" motions of a piston in a cylinder (connected to a crankshaft), and of a pendulum, are almost sinusoidal, but not quite. Their position graphs will differ slightly from the graph of position of an object moving around a circle.
__
On the other hand, if the circular motion is plotted as the length of the radius versus time, it will be a constant -- not "back and forth" at all.
__
In short, plots of similar motion will look similar.

Answer:
V₂ = 46.99 μL.
Explanation:
Given that
V₁ = 45.1 μL
T₁ = 24.7°C = 273 + 24.7 = 297.7 K
T₂ = 37.2°C = 273+37.2=310.2 K
Lets take ,The final volume = V₂
We know that ,the ideal gas equation
If the pressure of the gas is constant ,then we can say that
Now by putting the values in the above equation we get
V₂ = 46.99 μL.
The final volume will be 46.99 μL.
Answer:
Explanation:
the object will not move as the force exerted is not sufficient enough to overcome its force of friction
(A) A device that converts heat into work with 100% efficiency
It clearly violates the second law of thermodynamics because it warns that while all work can be turned into heat, not all heat can be turned into work. Therefore, despite the innumerable efforts, the efficiencies of the bodies have only been able to reach 60% at present.
