A circular current with center O and radius R = 20 cm has a current of magnitude I1 = 10A flowing through it. a) Calculate the magnitude of the induction vector from B at center O.
b) An infinitely long straight current of magnitude I2 = 5A flows through center O and coincides with the axis
of the circular current I1. Calculate the magnitude of the magnetic induction vector B produced by two currents I1 and I2 at
point M lies on the straight current I2 and is a distance x = 20 cm from the center of O.

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.

Frequency of electromagnetic waves that a radio station is assigned is called

Write a hypothesis about the effect of increasing resistance on the current in the circuit. use theformat and be sure to answer the lesson question. “how do changes in voltage or resistance affect current in an electric circuit? ”
