What is the main difference between a prokaryotic cell and a eukaryotic cell? a prokaryotic cell has flagella, and a eukaryotic cell does not. a prokaryotic cell has ribosomes, and a eukaryotic cell does not. a eukaryotic cell has a cell wall, and a prokaryotic cell does not. a eukaryotic cell has a nucleus, and a prokaryotic cell does not.

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to.in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?

You hang a book bag on a spring scale and place the bag on a platform scale so that the platform scale reads 23.7n and the spring scale reads 13.8n. what is the magnitude of the force that earth exerts on the bag?

While the change in blank will remain the same during a collision, the force needed to bring an object to a stop can be blank if the time if collision is blank
