An orchestra contains both string and wind instruments. The orchestra tunes their instruments in the morning at a temperature of TC = 15 °C. As they play, the temperature rises in the afternoon to TH 30 °C and falls in the late evening back to TC. As usual, the speed of sound in air increases with increasing temperature.

How has the increase in temperature from the morming to the afternoon altered the speed of sound in the air?

1. The temperature increase has not changed the speed, wavelength, or frequency of the sound.
2. The temperature increase has not altered the speed of sound in air; it's only decreased the frequency of the sound.
3. The temperature increase has not altered the speed of sound in air; it's only increased the frequency of the sound.
4. The temperature increase has increased the speed of sound in air
5. The temperature increase has not altered the speed of sound in air, it's only decreased the wavelength of the sound.
6. The temperature increase has decreased the speed of sound in the air increase has not altered the speed of sound in air, it's only increased the wavelength of the sound.

During physical science, ms. greene challenged her students to produce an energy transformation. james and jill wrapped a 4-inch nail with a coil of fifty turns of wire. they connected one end of the coil to one terminal of a knife switch. they connected the other terminal of the knife switch to the battery. finally, they connected the end of the coil to the other terminal of the battery. james held the tip of a 1-inch nail near the flat end of the 4-inch nail. jill closed the knife switch quickly and then opened it. the 1-inch nail was pulled toward the 4-inch nail. what is the best explanation of why the nail moved? a) electrical energy was converted to mechanical energy in the 1-inch nail. b) the 4-inch nail became an electromagnet and the magnetic force attracted the 1-inch nail. c) the electric current in the 4-inch nail was converted to mechanical energy in the 1-inch nail. d) the 4-inch nail had a positive charge and the 1-inch nail had a negative charge. opposites attracted.
