Answer:
28.8 cm
Explanation:
Magnification in a microscope is:
M = Mo * Me
Where
Mo: magnification of the objective,
Me: Magnification of the eyepiece.
The magnification of the objective if:
Me = npd/fe
Where:
npd: near point distance
fe: focal length of the eyepiece
The magnification of the objective:
Mo = d/fo
Where
d: the distance between lenses
fo: focal length of the objective
Then
M = npd/fe * d/fo
d = M * fe * fo / npd
d = 12 * 5 * 12 / 25 = 28.8 cm
Answer: Musical theater is like acting in a musical.
Explanation: Other dance styles don't involve singing.
Answer:
Explanation:
If you are asking for how much a cubic meter of iron would weight, you need to find its density.
The density of iron taken from the periodic table is , therefore a single cubic meter would weight 7870 kg, which written in scientific notation would be
The term used for the total radiation that is reflected by a surface is albedo. It is the percent of solar energy that is being reflected from our Earth back into the space. It is a dimensionless value since it is a percentage and ranges from a value of zero (corresponds to a perfect black body where it absorbs all of the radiation) to one (corresponds to a white body where all radiation is being reflected). This term is very useful in astronomy, climatology and environmental management. The average albedo of Earth is found to range from 30 percent to 35 percent due to the clouds present in the atmosphere.
Fluid mechanics deals with pressure and internal forces in the fluid. So the correct answer should be a) how fluids do work.
If you put two solids in contact, there will be a contact force created between them. Since Pressure = Force / Area, the correct answer should be b) exert pressure on each other.
