Diagram 1 shows a beam balance. A beaker with a wire loop balances the standard masses. The beaker is then removed and hung from a spring. The spring extends by 5.0 cm, as in diagram 2. The experiment is repeated with the same apparatus on the Moon, where the acceleration of free fall is less than on Earth. Which statement describes what happens on the Moon? A. The beam balance is balanced and the spring extends by 5.0 cm. B. The beam balance is balanced and the spring extends by less than 5.0 cm. C. The right-hand balance pan is higher and the spring extends by 5.0 cm. D. The right-hand balance pan is higher and the spring extends by less than 5.0 cm.

What are igneous intrusions and extrusions

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.
