If an arrow is shot upward on mars with a speed of 52 m/s, its height in meters t seconds later is given by y = 52t − 1.86t2. (round your answers to two decimal places.) (a) find the average speed over the given time intervals.

The sample with the lowest specific heat capacity will have the greatest temperature increase. in this case, it would be platinum.

Sounds propagates through some kind of medium. usually it's air, but it goes just as well through solid objects like walls, windows etc. a soundwave will compress the (air)molecules in front of it, and if this increased density wave hits your ears, you register it as sound. solid objects like walls are a lot denser than air, this means that they will damp a wave, but also carry it easier.
