Explain what causes an electron to move toward one end of a wire when the wire is moved across a magnetic field. (Select all that apply.) The interaction between the charge of the electron and the magnetic field creates a force on the electron, causing it to move.
A moving electron creates its own electric field.
A moving electron creates its own magnetic field.
The magnetic field induces a region of positive charge which attracts the electron toward one end of the wire.
The interaction between the electric field of the electron and the magnetic field creates a force on the electron, causing it to move.
An electron has its own magnetic field.
None of these are true.
The interaction between the magnetic fields creates a force on the electron, causing it to move.

An air-filled capacitor is formed from two long conducting cylindrical shells that are coaxial and have radii of 26 mm and 103 mm. the electric potential of the inner conductor with respect to the outer conductor is - 700 v (k = 1/4πε 0 = 8.99 × 109 n · m2/c2) the energy stored in a 1.0-m length of this capacitor is closest to

Read the passage about bird food and bird watching. noted scientist dr. elsa birde described the effect of adding a mixture of dried apples and raisins to the previous feed of sunflower seeds, millet, thistle seed, and cracked corn in bird feeders in her yard. over three years, dr. birde observed that the new mixture increased the number of songbirds at her feeders, especially during the months of april and may. as she has done for several years, dr. birde recorded, at the same time each day, the number of birds at each of her four feeders. she noted that the third year using the mixture coincided with the largest increase. there was a twenty-five percent increase in the number of songbirds over times when this mixture was not used. dr. birde also noted that in the third year she used a specific ratio of the ingredients, carefully measuring, which she had not done in previous years. the third year also had a warmer than normal spring, and a construction project began in a neighborhood near dr. birde’s. dr. birde is now going to produce this formula for sale and advertise to customers that they may see the same twenty-five percent increase in songbirds at their feeders. dr. e. birde, journal of scientific bird feeding which scientific claim can be made? a. songbird numbers will increase due to the effects of climate change increasing global temperatures. b. songbirds appear more often in april and may. c. a combined ratio is the main reason songbird numbers increased. d. a study by dr. birde showed that the number of songbirds in her yard increased due to a modified food source.
