An observer in the earth reference frame observes cart a and cart b moving toward each other with the same speed until they collide and come to rest. consider this event as seen by observer a moving along with cart a. assume that this observer matches cart a's initial velocity but does not collide with cart b (that is, observer a continues along at the same velocity that cart a had initially). would the observer in the earth reference frame and observer a obtain the same value for the initial velocity of cart a? yes no would the observer in the earth reference frame and observer a obtain the same value for the final velocity of cart b after the collision? no yes would the observer in the earth reference frame and observer a obtain the same value for the relative velocity of the two carts after the collision?

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.
