What do you call cool magnetic fields that dot the surface of the sun?
The dark spots on the surface of the sun are sunspots. They are caused by intense magnetic activity which stops convection and causes a relatively cool spot.
Can electric field lines do work?
Yes. Work is force times distance, or technically the dot product of vector force times vector distance. Electric fields exert force on charge and the force does work when the charge moves in the direction of the electric force. (In the converse, when the movement of charge is against the direction of force, work is transformed into stored electromagnetic energy.) Technically, it is the electric field that does work and not the field line. Mother nature produces electric fields, but humans can not see electric fields. Humans invented the idea of field lines to create a mental picture of the field. The two most common ways are to draw lines in space or to draw a collection of arrows in space. Note: One should not confuse this answer with the question of whether work can be done by a magnetic field. A magnetic field can not do work because the direction of the magnetic force is always perpendicular to the direction of motion of charge and hence the dot product of force and distance moved is always zero.
What is the relationship between the gradient dot product and vector calculus?
The gradient dot product is a key concept in vector calculus. It involves taking the dot product of the gradient operator with a vector field. This operation helps in understanding the rate of change of a scalar field in a given direction. In vector calculus, the gradient dot product is used to calculate directional derivatives and study the behavior of vector fields in three-dimensional space.
What is the electric flux through the surface?
The electric flux through a surface is a measure of the total electric field passing through that surface. It is calculated by taking the dot product of the electric field and the surface area vector. The unit of electric flux is Newtons per Coulomb (N/C).
What is the surface integral of electric field?
The surface integral of the electric field is the flux of the electric field through a closed surface. Mathematically, it is given by the surface integral of the dot product of the electric field vector and the outward normal vector to the surface. This integral relates to Gauss's law in electrostatics, where the total electric flux through a closed surface is proportional to the total charge enclosed by that surface.
What are the cool magnetic fields that dot the surface of the sun?
Magnetic fields that dot the surface of the sun are known as sunspots. Although they are hardly cool in temperature, they are much colder than surrounding areas, which causes them to be visible as darkened spots.

Cool
Why Microsoft has chosen the name Dot Net for Ms Dot Net?
cause it sounds cool i guess

Its a storm on the plantets surface
What does a party dot tattoo mean?
That you drunkenly and foolishly tattooed a dot on yourself to be one of the "cool" kids with a party dot tattoo. It means nothing, and looks like a freckle or a mole.
Do smileys look cool?
Yess'! (: Smiley's are the bomb dot com. xD "]]
Is there a black dot in the middle of the Sun?
No, there is no black dot in the middle of the Sun. The Sun is a bright, glowing ball of gas and does not have any visible surface features like a black dot.
What does a spore look like?
it looks like a brown dot, puffy very cool
What is it called to place small pieces of butter over the surface of a food?
to dot
