Answer:
The answer is below
Explanation:
Distance is a measurement of how far apart two points are. Distance is a scalar quantity, i.e. it has magnitude and no direction.
Total distance traveled = distance traveled north + distance traveled east + distance traveled south
Total distance traveled = 100 + 50 + 60 = 210 meters
Displacement is the shortest distance between the starting and end points.
displacement² = 50² + (100 - 60)²
displacement² = 2500 + 1600
displacement = 64 meters
The displacement of the journey is vector, because displacement is a vector quantity.
If you're given the force and the length of time that the force acted,
then you can determine momentum, with units of [mass-length/time].
Without more information, you can't determine power, watts, energy,
joules, or distance.
A cup of tea/coffee transfers heat via conduction, convection and radiation.
Conduction:
- Heat transfer from a coffee to the spoon is in direct contact
- Inner part of the tea cup against hot liquid will transfer heat to the outer part and saucer.
Convection:
Movement of molecules within the coffee. Hot molecules of the tea at the middle of the drink will be eventually make their way to the outer part of the drink near the tea cup, where they will loose their heat.
Radiation:
Thermal radiation is the loss of heat from a solid object in to atmosphere via the release of electromagnetic radiation. So hot outer edge of the teacup loss the energy to its surroundings via thermal radiation.
The appropriate term is latent heat. This energy is released as the water changes state from a gas to liquid....a liquid to solid etc. the latent heat is either absorbed or given off by the water as it changes its physical state. Latent heat of fusion is associated with freezing a liquid or melting a solid.
