An electric field is constant at every point on a square surface that is 0.80 m on a side. this field has a magnitude of 3.5 n/c and is oriented at an angle of 35° with respect to the surface, as the drawing shows. calculate the electric flux φe passing through the surface.

What is the measurement of how fast an object moves relative to a reference point?

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.

Selma made a diagram to compare convection and radiation. which label belongs in the area marked x? must involve temperature differences between substances or objects only occurs when molecules are in direct contact involves the movement of fluids based on density differences can occur where there is little or no matter
