Conceptual Impulse Impulse is an object's change in momentum, Impulse states that the time it takes to change momentum
and the force required are inversely proportional. This means that a longer time takes less force and a
shorter time requires more force
Two friends are riding bikes next to each other and use the brakes to come point
to a stop. If one friend uses more force on the brakes, what can you say
about the time it takes them to stop?
It takes them more time to stop
It takes them less time to stop
It takes them the same amount of time to stop

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.

A200-n force is applied to the foot-operated air pump. the return spring s exerts a 2.6-n·m moment on member oba for this position. determine the corresponding compression force c in the cylinder bd. if the diameter of the piston in the cylinder is 40 mm, estimate the air pressure generated for these conditions. state any assumptions. enter a positive number for the compression force c.

An object is placed in front of a concave mirror between the pole and the focus of the mirror, what is the nature of the image formed by the mirror
