This is why Yahoo failed U0001f92f #shorts

In the transformation of ""_(92)""^(238)U to ""_(92)""^(234)U , if one emission is an alpha particle, what should be the other emission(s)?

Assertion : The focal length of the mirrorr is f and distance of the object from the focus is u , the magnification of the mirror is f//u . Reason : Magnification =("Size of the image")/("Size of object" )

A stone of weight W is thrown straight up from the ground with an intial speed u. If a drag force of constant magnitude f acts - on the same through out its flight , the speed of stone just before reaching the ground is (1) usqrt((W-f)/W) (2) usqrt((W+f)/f) (3) u sqrt((W+f)/(W-f)) (4) u sqrt((W-f)/(W+f))

A silver cup is plasted with silver by passing 0.001 F of electricity . The amount of Ag deposited is (Ag = 107.8)

Let F(alpha)=[[cos alpha,-sin alpha,0sin alpha,cos alpha,00,0,1]], where alpha in R Then (F(alpha))^(-1) is equal to F(alpha^(-1)) b.F(-alpha) c.F(2 alpha)d.-[[1,11,0]]

Why is short run marginal cost curve 'U'-shaped?
