What else can I help you with?
F equals ma in linear and Rotational force equals I x alpha. And torque for linear T equals max R. why rotational torque is I x alpha?
I'm going to let Paul A. Tipler (Aka my 50lb physics textbook) answer this one.First to explain why I (rotational inertia) is in the equation.T (not period, but tao, or torque) is defined as F x RBy Newton's second law F = ma, in a rotating body a = alpha x RF = m(alpha)Rif you multiply both sides by RF x R = m(alpha)R2Recall F x R is TT = m(alpha)R2Sum the torques in the entire bodySigma(T) = Sigma(mR2(alpha))Therefore I is defined as Sigma(mR2), or for a continuous object(a disk) I = the Integral of (R2dm)Therefore, Sigma(T) = I x alphaThis is analogous with Newton's second law: F = ma. Where in rotation F --> T, m --> I, a --> alpha
What does the sigma letter stand for in physics?
Sigma Basically means the sum of something For Example: (sigma)F=ma This means the sum of the force acting on the object is equal to the mass multiplied by the acceleration!
What is the significance of the sigma symbol in the context of electrical conductivity in physics?
The sigma symbol represents electrical conductivity in physics. It is a measure of how well a material can conduct electricity. A higher sigma value indicates better conductivity, while a lower value indicates poorer conductivity. The sigma symbol is important in understanding the flow of electrical current through different materials.
What is the 1 sigma uncertainty associated with the measurement of this keyword?
The 1 sigma uncertainty is a measure of the range within which the true value of the measurement is likely to fall.
What is the Energy of uniformly charged spherical shell having radius R and a charge Q on it?
(1/4pi[epsilon]_0)*Q^2/2R This can be derived from the fact that a spherical shell seemingly has a potential of a point charge (that is, k*Q/R) and W =½ int Vdq, where dq can be replaced with a [sigma]dA=[sigma] 4 pi r dr and sigma= Q/A = Q/4piR^2 => int½ Vdq = int ½k*Q/r*Q/(4piR^2)*4pir dr from 0 to R = k*½*Q^2/R^2 int dr from 0 to R = ½kQ^2/r=k*Q^2/2r.

Does yale have fraternities or sororities?
When I was an undergraduate there in the late 1960's, Harvard had a chapter of Sigma Alpha Epsilon--which I believe was the only fraternity on campus. I'm not sure what the current situation is.
Where would one find out the definition of sigma alpha epsilon?
Actually the best place to get more information on "Sigma Alpha Epsilon" would be the related English Wikipedia page. The article is entitled accordingly "Sigma Alpha Epsilon".
