Acoil has n turns enclosing an area of a. in a physics laboratory experiment, the coil is rotated during the time interval δt from a position in which the plane of each turn is perpendicular to earth's magnetic field to one in which the plane of each turn is parallel to the field. the magnitude of earth's magnetic field at the lab location is b.

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.

The amount of work done is determined by 2 factors. describe an example of work (using the scientific definition) list the 2 factors that determine the amount of work done.

Is the vertical component of velocity ever zero?
