The second speaker's cone and coil will vibrate, causing a change in magnetic field on the magnet, which will induce a current along the wire to the first speaker. The current induces a magnetic field on the first coil, which is then attracted and repelled from the magnet, causing the cone to vibrate and produce sound
Answer:
The answer is stage one: denial.
Explanation:
It is the first of the five stages of grief, and helps us cope with with the loss (or the possibility of loss). After the shock, the person might feel that life is meaningless or unfair, and might simply continue living in an automated, dull way.
In this stage, the healing process starts, but all the supressed emotions arise in time, which leads to anger.
Answer:
Because lip reading is HARD
Explanation:
You can't be 100% accurate lip reader. Since someone is deaf they cant hear, so all they can go off of is your lips. Don't you think it would be easier to just look at someones hands. Also I think that a deaf person would prefer to use sign languages because other people around them might be deaf too. But maybe they would talk if someone they were talking to did not know sign language.
Evolution isn't a steady process. When the environment changes, the organisms have to adapt quickly or perish. A theory known as punctuated equilibrium accounts for this. Any changes in then environment brought on by natural or artificial changes will cause animals to evolve to those changes. It may be that they just have to migrate where the climate is more suitable. When you look at geologic sequences, you can often see the different environments as the climate changed and a new suite of animals and plants took over.
<span>It is fantasy to claim that the "old" environment was stable before humans came along unless you live in the tropics. There was a mile of ice over NYC and Chicago 15 thousand years ago. </span>
<span>Geologic changes can affect evolution by creating population splits which allows for speciation. For example, the thrusting up of a mountain range may cause one population to split into two. The separate populations may then evolve on their own sometimes into new niches. One population may stay relatively similar and the other may change dramatically.</span>
