The magnitude of centripetal force is calculated by the relation Fc=mv2/r where m is mass of the object,v speed of the object (constant) and r radius of the curved path.If the radius of curved path is large then centripetal force is decrease. Therefore it is easy to turn along a curved path of large radius as compared to a curved path of short radius.
Find the radius of the larger wheel.Find the radius of the axle.Divide the radius of the large wheel by the radius of the axle to find the mechanical advantage. MA =r (large wheel )/ r (axle)
The angle of incidence equals the angle of reflection. Always. If the surface is curved, this is still true. Now for some caveats. 1. If the "beam" has zero width, then there really is no complication. Measure angles relative to the line perpendicular to the surface and in the plane of incidence at the point the beam strikes the surface and everything works out perfectly. 2. If the beam has a finite width, then everything still works out, but the beam strikes the surface at more than one point and the reflected beam goes away from the surface at more than one point but at each point, the angle of incidence equals the angle of reflection, but the angle of incidence is different at each point on the curved surface. Still, at each point, one measures from the perpendicular to the surface at that point, just as described above. Some more technical stuff. We may say a beam has zero width if the width of the beam is very much smaller than the radius of curvature of the surface measured at the place where it strikes the surface. Under any circumstances, the beam reflected from a curved surface will spread, i.e. be dispersed at a range of angles relative to the incoming beam and that range depends on the radius of curvature of the reflecting surface. As mentioned above, this is small if the beam is narrow, but if you are observing reflection far enough from the reflecting surface, one can observe the spread. All this assumes "ray optics" where the sizes of the beam diameter and the radius of curvature are large compared to the wavelength of the light. It all gets more complicated otherwise.
Not at all, as long as the mass of the 'bob' is large compared to the mass of the string.
An amoeba is about 200 - 700 micrometers, and an air particle is about 0.00001 micrometers. Thus, an amoeba is about 5 million times bigger.
That's because the strong nuclear force only acts at very short distances.
Atomic radius of Iodine is very large compared to potassium.
a Gulf.
by radius yes, 2nd largest
Polaris has a radius which is around 5000 as big and so it occupies a volume which is approximately 125 billion times as large.
A wooly mammoth is a large, elephant- like mammal. It is covered with thick hair, and has large, curved tusks. Think along the lines of Manny from Ice Age.
The radius is the large bone in the arm.

The diameter is twice as large as the radius.
francium
Compared to other planets, yes it is small. But compared to a house, no, it is very large...
