An object is 25.0 cm away from a concave lens of focal length -5.0 cm. If the height of the object is 2.7 cm, what is the image height? Group of answer choices 0.35 cm -0.35 cm -0.45 cm 0.45 cmA sound wave is produced and begins to travel from left to right through four different media. The speed of the wave varies as it travels. The media are solid, liquid, gas, and a vacuum, but not necessarily in that order. Chart. 1 = 344 m/s. 2 = 5,000 m/s. 3 = 1,450 m/s. 4 = no transmission transmission chart 1 2 3 4 344 m/s 5,000 m/s 1,450 m/s No transmission Which speed MOST likely represents a gas?
