If two countries claim the same region, generally, it likely leads to tensions between them, so you know that the answer is D). even without knowing specifically about India and Pakistan.
And it is: India and Pakistan have a very strained relationship and had even some military conflicts and nuclear arms race because of Kashmir.
Naturalists of Steno’s day were becoming convinced that matter was composed of different combinations of tiny “corpuscles”—what today we would call molecules. Steno argued that the corpuscles in the teeth were replaced bit by bit, by corpuscles of minerals. In this gradual process, the teeth didn’t lose their overall shape as they turned from tissue to stone.
Answer:
In vector calculus, the curl is a vector operator that describes the infinitesimal rotation of a vector field in three-dimensional Euclidean space. At every point in the field, the curl of that point is represented by a vector. The attributes of this vector (length and direction) characterize the rotation at that point. The direction of the curl is the axis of rotation, as determined by the right-hand rule, and the magnitude of the curl is the magnitude of rotation. If the vector field represents the flow velocity of a moving fluid, then the curl is the circulation density of the fluid. A vector field whose curl is zero is called irrotational. The curl is a form of differentiation for vector fields. The corresponding form of the fundamental theorem of calculus is Stokes' theorem, which relates the surface integral of the curl of a vector field to the line integral of the vector field around the boundary curve.
The alternative terminology rotation or rotational and alternative notations rot F and ∇ × F are often used (the former especially in many European countries, the latter, using the del (or nabla) operator and the cross product, is more used in other countries) for curl F.
Unlike the gradient and divergence, curl does not generalize as simply to other dimensions; some generalizations are possible, but only in three dimensions is the geometrically defined curl of a vector field again a vector field. This is a phenomenon similar to the 3-dimensional cross product, and the connection is reflected in the notation ∇ × for the curl.
Explanation:
First we need to convert them into improper fractions
2 2/5= 12/5
6 4/5= 34/5
to divide fractions you flip the second one and multiply them
12 5 12
---- × ---- = -----
5 34 34
then simplify
12/34=6/17
the correct answer is 6/17
I hope I've helped!
