depends on how young it starts usually at age 10 or 12 sometimes 13 are the most common ages to start this
The change needed is from 8 to 28, a change of 20 m/s. At a rate of 2m/s/s it will take 10 seconds for it to happen (2x10=20). I hope this helps.
Explanation:
temperature can cause change of state of a substance and change of state is a physical change. A physical change simply put is a change that isn't permanent...a change that can be reversed. the change of state of a substance is a physical change because addition of heat or a rise in temperature makes a solid melt and the removal of heat turns it back to solid

<span>-Electromagnetic waves carry transverse vibrations in electrical and magnetic fields, not vibrating particles.
-Electromagnetic waves do not need matter to travel through - they can travel through empty space (a vacuum).
<span>-In a vacuum, all electromagnetic waves travel at approximately 3 x 108 m/s - the fastest speed possible.
</span><span>-When electromagnetic waves travel through matter (for example, light through air or glass), they travel a bit slower than this but rarely less than half as fast as in a vacuum. The value for light travelling through an optical fibre, for example, is taken as 2 x 108 m/s.</span></span>
