The dispersion of light is the phenomenon of splitting of a beam of white light into its seven constituent colours when passed through a transparent medium. It was discovered by Isaac Newton in 1666.
<u>Explanation</u>
The Iron is incontact with the shirt. So, heat is transferred from the iron to the shirt because they are in contact.
Before the contact, there is temperature difference between the shirt and the iron. When they come into contact there must be exchange of heat energy, this happens until equilibrium state is reach.
False they simple machines do not reduce the amount of work you do it would just reduce the amount of force you use.
Given that:
mas (m) = 0.14 Kg ,
height (h) = 16 m,
Determine gravitational potential energy ?
Gravitational potential energy = m × g × h
= 0.14 × 9.81 × 16
= 21.97 Joules
<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>
