a laboratory cart mi=500g is pulled horizontally across a level track by a lead weight m2=25g suspended vertically off the end of a pulley. If the lead weight falls 85cm then find speed of the system

Initially, a particle is moving at 5.33 m/s at an angle of 37.9° above the horizontal. two seconds later, its velocity is 6.11 m/s at an angle of 54.2° below the horizontal. what was the particle's average acceleration during these 2.00 seconds in the x-direction (enter first) and the y-direction?

Acombination reaction is when two or more combine to form one product. a decomposition reaction is when a substance breaks down into two or more simpler substances in a chemical reaction.

Explain what will happen if decomposers were apsent from a forest ecoysystem.
