A cart moves on a surface when it is pulled by a constant force. The total mass of the cart is 2.0 kg and the accelerometer data show that its acceleration is 0.4 m/s2. Another trial is done with the same constant force, but the total mass of the cart is changed to 0.5 kg.
What acceleration should the accelerometer read?
A. 0.1 m/s2
B. 0.2 m/s2
C. 0.4 m/s2
D. 0.8 m/s2
E 1.6 m/s2

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. threat method number of species that benefit number of years to see benefit habitat fragmentation reforestation 450 8 introduced prey species biological augmentation 150 2 which statement is an accurate explanation of the information in the table? a. biological augmentation would benefit only a few species because it is typically not very effective. b. biological augmentation would take less time to be effective because it targets the majority of prey species. c. reforestation would take the longest time to be effective because trees take several years to grow. d. reforestation would not benefit many species because most forest species live on the ground.

Johnny rode his bike to a friend's house 4 blocks down the street in his neighborhood. he immediately rode back home once he realized his friend was not able to play. what was his displacement for the total bike ride? how did you determine this? what could we use as a reference point to determine he was in motion during his bike ride? why can you use it as a reference point
