The bat emits a sound wave with a frequency of 25.0 kHz and a wavelength of 0.0136 metres.
Calculate the speed of this sound wave.

The calculation that you then need to do is 25000 x 0.0136 = 340. You must not forget the units of speed, which here are metres per second, or m/s. Your final answer is 340 m/s.

answer; how far out of place which the object finished relative to the starting location;

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
