Given the wavelength of the corresponding emission line, calculate the equivalent radiated energy from n = 3 to n = 2 in both joules and electron volts. Also calculate the frequency of the wave.

Athermometer is removed from a room where the temperature is 70° f and is taken outside, where the air temperature is 10° f. after one-half minute the thermometer reads 60° f. what is the reading of the thermometer at t = 1 min? (round your answer to two decimal places.) ° f how long will it take for the thermometer to reach 30° f? (round your answer to two decimal places.)

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz.

The graph describes the motion of an object. the object moves with from a to b. it from b to c. it moves with from c to d.
