When a spoon is in a cup of water, is called refraction.
You would do distance divided by speed. So 150÷3, which would equal 5km per hour.
Answer:
A d-t graph's slope is equivalent to the speed and direction while a v-t graph's slope is equal to its acceleration. A constant slope for a d-t graph means that the speed is constant. The area underneath a v-t graph would be its distance.
Explanation:
The picture is very blurry I wish I could help
The extra energy allows the molecules to convert states of molecules.
<h3>What is heating?</h3>
When the temperature is increased , the body or particle is said to be heating.
The water in this pot is in the process of changing from a liquid to a gas. Thermal energy is still being added to the water as it vaporizes, but its temperature and the motion of its particles are not increasing.
When the liquid is converted to gas, the temperature reaches the boiling point of water. After boiling, the heat added up will only make the particles to convert its phase and go away in then atmosphere.
Thus, extra energy added helps molecules of water to change its state from liquid to solid.
