To maximize your cordless phone battery life, make sure to leave your phone off the base every once in a while until it is dead. Then leave it on the base until it is fully charged. You should leave your phone on the base for at least 24 hours to charge it fully. There is no need to avoid rechargeable batteries. They can save you significant amounts of money over time. Don't be scared off by the 'memory effect'.
In addition to being a great toy, the Slinky is an excellent device for creating and studying waves. A slinky can easily demonstrate the two basic types of waves, longitudinal and transverse. In a. longitudinal wave. the particles move parallel to the direction the wave is moving. In a. transverse wave. the particles move at right angles to the direction of wave travel.
Best Answer: 1.A mechanical wave is a wave that requires a medium through which to transmit energy. Sound waves, waves in a Slinky, and pressure waves are all examples of this.Sound waves need air molecules in order to exist; the Slinky waves need the Slinky, and the waves in the ocean need the water.nce this initial energy is added, the wave will travel through the medium until all the energy has been transferred. There are three types of mechanical waves. Transverse waves are waves that cause the medium to vibrate at a 90-degree angle to the direction of the wave.
