3. If a rocket in space is moving at a constant velocity of 9.8 m/s and then uses its propulsion system to accelerate to 10.5 m/s during a 3.0 minute burn, what would be the acceleration of the
rocket? (remember to change minutes to seconds - there are 60 seconds in 1 minute)

Describe the path of a ray that approaches a mirror parallel to the principal axis.

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?

When is a current produced? when the terminals of an electrochemical cell are connected by a wire if the electric circuit is opened in an electrochemical cell if the electrolyte is removed from an electrochemical cell when the electrodes are reversed in an electrochemical cell
