Some types of waves require a (4) to travel through, rather than a vacuum. These waves are known as a (5), or a compression wave. An example of this kind of wave is (6), or a wave that has the ability to do work through vibrations. These types of waves have a pattern to them. Regions of the wave where air particles are closest together are called (7), and areas where the air particles are furthest apart are called (8).

According to newton’s first law of motion, which force is expected to cause a body to accelerate?

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
