When a car collides with a truck, intuitively the car reacts more during the collision. (You’d rather be riding in the truck!) So occupants in the car would feel the bigger force. In the meantime, Newton’s 3rd law states: The force exerted by object A on object B is equal in strength (but opposite in direction) to the force exerted by object B on object A. How would you reconcile the law with the collision feeling?

Awoman stands a distance d from a loud motor that emits sound uniformly in all directions. the sound intensity at her position is an uncomfortable 2.0×10-3 w/m2. at a distance 2.6 times as far from the motor, what are (a) the sound intensity and (b) the sound intensity level relative to the threshold of hearing?

What should the power status of a circuit be when measuring resistance with an ohmmeter?

As part of your daily workout, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. when you push the platform, you compress the springs. you do an amount of work of 79.0 j when you compress the springs a distance of 0.230 m from their uncompressed length. (a) what magnitude of force must you apply to hold the platform in this position? (b)how much additional work must you do to move the platform a distance 0.230 m farther? (c) what maximum force must you apply to move the platform a distance 0.230 m farther?
