Determine the potential difference across 5-ohm resistor and determine the potential difference across the battery

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

Suppose an objects initial velocity is 10m/s and it’s final velocity is 4 m/s. mass is constant. what can best be concluded about the object based in the work-energy theorem

At very high pressures, gases become and will eventually a) more dense; become hotter b) more dense; change to a liquid or solid c) less dense; combust d) less dense; turn into a liquid
