A“dip needle” is a small magnet mounted on horizontal axis so that it can swivel up or down (like a compass turned on its side. where on earth will a dip needle point most nearly vertically? where on earth will it point most nearly horizontally?

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?

A10 kg box initially at rest is pulled 18 meters across a horizontal, frictionless surface by a 40 n force. what is the block’s final velocity over the 18 meters?

The process of predicting values that extend beyond the range of data points is called absolute value extrapolation interpolation prediction for any given: )
