The bicycle and the person on it are in motion. therefore anything is motion has energy.
That's false. Think about a stone or a baseball, during the first
several seconds after you tossed it straight up, before it reaches
its maximum height and starts to come down again.
There's no upward force on it during that time.
Also, after a roller coaster reaches the top of the FIRST hill, there's
no upward force on it for the whole rest of the ride, even though it
coasts up many more hills.
Answer:
Explanation:
= Refraction index of water = 1.333
= Refraction index of air = 1
= Angle of sunlight = 30°
From Snell's law we have
The angle measured from the vertical does the sunlight strike thesurface of the water is
Boiling water has a lot more heat than the oven's air (even though the air has a higher temperature). ... A match has a greater temperature than the iceberg because the average molecule in the match is moving faster than the average molecule in the iceberg
16. Solids cannot transport heat through convection. Because solids are stuck in place so they can't flow and since they can't flow, there is no convection.
17. It is because the metal conducts heat faster that it feels colder than the wood, which conducted heat slower. In other words metals are good conductors of heat. It takes away your body heat as you touch it and which makes your body temperature to drop, therefore you feel the coldness when you touch a piece of metal.
