An electrostatic dipole is formed by two charges with q = 2 ∙ 10-9 C and distance away from one another d = 1 mm. The positive charge
is positioned at the point (0, d / 2,0), the negative charge at the point
(0,-d / 2.0). Determine the value of the electric field generated by
the dipole at the point of coordinates (0, a, 0) where a = 1 m

The temperature in gavin's oven is a sinusoidal function of time. gavin sets his oven so that it has a maximum temperature of 280°f and a minimum temperature of 240°. once the temperature hits 280°, it takes 20 minutes before it is 280° again. gavin's cake needs to be in the oven for 30 minutes at temperatures at or above 270°. he puts the cake into the oven when it is at 260° and rising. how long will gavin need to leave the cake in the oven? (round your answer to the nearest minute.)
