Acommon flashlight bulb is rated at 0.40 a and 3.0 v (the values of the current and voltage under operating conditions). if the resistance of the bulb filament at room temperature (20°c) is 1.32, what is the temperature of the filament when the bulb is on? the temperature coefficient of resistivity is 5.4 x 10c material. for the filament number units the number of significant digits is set to 2; the tolerance is +/-2%

How much energy is supplied to each coulomb of charge that flows through a 12-v battery?

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.

How is an electron dot structure used to represent a covalent bond?
