A solid nonconducting sphere of radius RRR carries a charge QQQ distributed uniformly throughout its volume. At a certain distance rrr1 (rrr1 < RRR) from the center of the sphere, the electric field has magnitude EEE. If the same charge QQQ were distributed uniformly throughout a sphere of radius 2RRR, the magnitude of the electric field at the same distance rrr1 from the center would be equal to

What property is a characteristic of a substance that can be observed and does not change the identity of the substance

The transfer of heat through the movement of a gas or liquid a. convection b. conduction c. radiation

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.
