Asquare coil, enclosing an area with sides 6.1 cm long, is wrapped with 2,578 turns of wire. a uniform magnetic field perpendicular to its plane is turned on and increases to 0.49 t during an interval of 1.5 s. what average voltage (in v) is induced in the coil? express the answer with two decimal places.

What happens to atoms and chemical bonds during a reaction?

An element becomes a positively charged ion when itloses protons. loses electrons. gains electrons. gains neutrons.

The starship enterprise is caught in a time warp and spock is forced to use the primitive techniques of the 20th century to determine the specific heat capacity of an unknown mineral. the 125-g sample was heated to 96.3°c and placed into a calorimeter containing 85.9 g of water at 20.0°c. the heat capacity of the calorimeter was 14.2 j/k. the final temperature in the calorimeter was 24.5°c. what is the specific heat capacity (in j/g°c) of the mineral? enter to 4 decimal places.
