Consider the radial field f = (x, y, z) and let s be the sphere of radius a centered at the origin. compute the outward flux of f across s using the representation z = plusminus squareroot a^2 - x^2 - y^2 for the sphere (either symmetry or two surfaces must be used.) the net outward flux f across s is 4 pi a^3.

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
