What is the shortest possible time in which a bacterium could travel a distence of 8.4 cm across a petri dish at a constant speed of 3.5mm

Debbie places two shopping carts in a cart corral she pushes the first cart which then pushes a second cart what force is being exerted

An object weigh 40n in air ,weigh 20n when submerged in water,and 30n when submerged in a liquid of unknown liquid density.what is the density of unknown of liquid?

In order to do work, the force vector must be question 1 options: in a different direction than the acceleration vector. in a different direction than the displacement vector. in the same direction as the displacement vector and the motion. in the same direction as the acceleration vector.
