Magnetic length is related to the larmour radius: r = mv/(qB) = mvr/(qBr)=L/(qBr)Since L is quantised as m(l)h; m(l) =magnetic quantum number= integers, so let it be unity for the smallest value or r, then r^2=h/(qB) and the vale of r with m(l) = 1 is called magnetic length l(B): so l(B) = sqrt(h/qB)The physical interpretation of this length is that the area swept out by this length (2*pi*l*l) contains one quantum of magnetic flux.
The other word for atomic radius includes the Van der Waals radius, ionic radius, and covalent radius. The atomic radius refers to half the distance between the nuclei of identical neighboring atoms in the solid form of an element.
For a solid cylinder, divide the radius of the flywheel by the square root of 2, to get the radius of gyration.
The expression for tan @ is F/B Here F = mu not n I / 2a mu not = permiability of air which equals to 4pi x 10-7 H/m n = number of turn in the TG a - radius of coil in TG in meter I = the current flowing through in ampere B is the earth's magnetic field. Hence B = F / tan@ Here @ is the angle of deflection in the TG when two perpendicular fields are applied. Here one is earth's magnetic field whose induction is B tesla and F is the magnetic field produced due to flow of current in the TG coil
The radius of a circle is 1/2 of the diameter.
raduis of amper loop is greater than than the radius of its own toriod..than this toriod is called ideal toriod
volume of the cube - volume of the sphere = volume enclosed between the cube and sphere
==================================Answer #2:I believe you want the volume of the shell ... the material between theinside and outside diameters ... whereas the first answer, above, gave youthe volume of the hole in the middle of everything. Here's my take on it:-- Volume of a sphere is 4/3 pi R3-- Volume enclosed by the outer radius is 4/3 pi (2)3-- Volume enclosed by the inner radius is 4/3 pi (1)3-- Volume of the material between them is4/3 pi (23 - 13) = 4/3 pi x 7 =28/3 pi = 29.32 m3. (rounded)The volume of a spherical shell is equal to the difference between the volume of a sphere with a radius of 2 m and a volume of a sphere with a radius of 1 meter:V= 29,321531433504736892318004910609 м3
All of the above. See related questions.
Assuming equal velocity. The alpha particle has twice the charge but four times the mass so it would have the wider radius.
because moon has small density and shorter radius than earth. specially density is more important for calculation of Gravity. there are some stars that have small radius but greater Gravity. why? because they have Larger density
This is not a fixed value, as it depends on the medium and magnetic field strength in which the explosion happens as well as the yield. In the lower atmosphere (where the air is nonconductive, except right around the device where it ionized the air itself) this radius may be well under the blast effect radius. In the ionosphere (where the air is already ionized) this radius could be in the hundreds or thousands of miles. Above the atmosphere (in the vacuum of space) this radius is zero (regardless of yield).
For a given perimeter, the greatest possible area is enclosed by a circle.A circle with a circumference of 18 has a diameter of (18/pi) and a radius of (9/pi).Its area is (pi R2) = (pi 92/pi2) = 81/pi = 25.78 (rounded)So an area of 42 cannot be enclosed by a perimeter of 18.
Everything within a 25 mile radius would be annihilated.
Beta tron is a device for speeding up electrons to extremely high energies with the help of expanding magnetic field. The beta tron differs from cyclotron in the two fundamental respects - 1) in beta tron the electron are accelerated by expanding magnetic field 2)the circular orbit has a constant radius.
Circumference is the perimeter of a circle Diameter is the length spanning a circle cutting through its center Radius is half the length of a circle's diameter Tangent is a straight line that touches a circle's circumference at one point Arc is part of a circle's circumference Chord is a straight line joining any two points of a circle's circumference Sector is the area enclosed by an arc and two radii Segment is the area enclosed by arc and a chord Circle's circumference divided by its diameter is equal to the value of pi Area of a circle = pi*radius squared There are 360 degrees around a circle
