Aball is dropped from the top of a tall building. slightly later a second ball is thrown downward and catches up with the first ball. when the two balls pass one another,
compare the magnitudes of their acceleration: (a) the acceleration of the second ball is greater.
(b) the acceleration of the first ball is greater.
(c) the acceleration of both balls is the same.
(d) the acceleration is larger for the second ball initially. the acceleration of the first ball is
lager later.
(e) the accelerations are both zero.

Aregion of space in which a measurable gravitational force is indicated by the force exerted on a test mass is called

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?

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.
