So we want to know the height Hi of the image if we know object distance Do=8 cm, image distance Di= 12 cm and the height of the object H0= 4 cm. The magnification formula is M=(Hi/H0)=(Di/Do). By multiplying the equation with H0 we get Hi=(Di/Do)*H0. Now we input the numbers and get: Hi=(12/8)*4=6 cm. So the height of the image Hi=6 cm.

What is the difference between condensation and conduction
aniked [119]

Answer:

Convection is the heat transfer due to the bulk movement of molecules within fluids such as gases and liquids, including molten rock. Condensation is the process by which water vapor in the air is changed into liquid water. Condensation is crucial to the water cycle because it is responsible for the formation of clouds. These clouds may produce precipitation, which is the primary route for water to return to the Earth's surface within the water cycle.

If you can simply pour sand into a cup then why is it not a liquid?
sleet_krkn [62]
If you, for example, poured it onto a wide cup with a volume equal to the total volume of the sand particles, the sand would not spread out to fill the container but would bunch up together in the middle.
