Many animals rely on their sense to alert them about changes in temperature. <span>Some ways that animals adapt for the seasons include migration, hibernation and physical changes that help them survive the differences in the weather. Hope this helps.</span>
1.35 x 10 to the power of 5 is 135000
If the floor is truly frictionless, then ANY force, no matter how small, applied for
ANY time, no matter how short, will set the block in motion. The force can then
be taken away, because on a frictionless surface, NO force is required in order
to keep the block moving.
The work done is equal to the kinetic energy you want the block to have. That
can be as much or as little as you feel like giving it.
Energy of the waves are redistributed to form a resultant wave with amplitude given by the summation of individual wave's amplitude.
<span>If the two waves are of same frequency, speed and amplitude and travelling in opposite direction den stationary waves are form.</span>
