An infinite wire and an infinite length conductor sheet are carrying currents I1 and I2, respectively. Both are placed parallel to the the z axis with the wire coinciding with the z axis. The conductor sheet has a semi-circle cross-section with radius b and negligible thickness. Derive an expression for the unit-length force acting on the conductor sheet due to the current passing in the wire.

At what point the certain object feels zero garvitational force between earth and the moon. take the required information from the book. required: distance away from earth or moon

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.

In a good thermo flask the main cause of heat loss is
