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>
The sum of more than one velocity vector.
Or the sum of an initial velocity vector and an acceleration vector integrated over time.
From 1st EQ. of uniform motion
1)20.9-3.44/6=t=2.91 sec
2)28= 0+4.22a
a=6.66m/sec^2
3) Instantaneous acceleration
<span>Scientists have obtained most of this information from natural geological activity.
</span>S-waves and p-waves are seismic waves- the waves of energy that travel through the Earth as a result of an earthquake .Both P- and S-waves travel easily through solids, but S-waves cannot pass through liquids, and they cannot pass through the outer core. Scientists know that Earth’s outer core is liquid because s-waves are not able to pass through it.<span> When an earthquake occurs there is a “shadow zone” on the opposite side of the earth where no s-waves arrive.
</span>So, one of the reasons <span>why scientists believe the outer core is liquid is the s-wave shadow zone.</span>
1. Increase the amount of gas. Adding more molecules of gas increase how much they collide therefore increasing the temperature.
2. Decrease the volume of gas. This also increases how much they collide and increases the temperature.
