Answer:
I. Overall magnification (TM) = x40
II. Overall magnification (TM) = x100
III. Overall magnification (TM) = x400
IV. Overall magnification (TM) = x1000
Explanation:
A microscope can be defined as an optical device that is typically used to make an enlarged (magnified) image of a minute (small) object and as such reveals all the little information about the object that cannot be seen by the natural human eye.
Mathematically, the overall (total) magnification of a microscope is given by the formula;
Overall magnification (TM) = Eyepiece magnification(EM) X Objective magnification (OM).
I. When EM = x10 and OM = x4
TM = EM * OM
TM = x10 * x4
<em>TM = x40</em>
II. When EM = x10 and OM = x10
TM = EM * OM
TM = x10 * x10
<em>TM = x100</em>
III. When EM = x10 and OM = x40
TM = EM * OM
TM = x10 * x40
<em>TM = x400</em>
IV. When EM = x10 and OM = x100
TM = EM * OM
TM = x10 * x100
<em>TM = x1000</em>
Answer:
26. Coal is burned at a power plant
27. In dams.
28. Gas heater.
29. Nuclear power plant.
Explanation:
Coal is burned at a power plant where Chemical energy is converted into thermal and then into electrical current. In dams, water falls from higher altitude in which Gravitational potential is converted to kinetic energy by revolving of turbines which produces electrical current. in heater, electrical energy is converted into radiant and also heat or thermal energy while the nuclear thermal energy is converted into electrical energy and this happen in the nuclear power plant.
Answer:
hi there!
Explanation:
• Variation light and variation in temperatura
For me these are the problem, because they had to move some plant to the outdoors, because they don´t have enough space inside. So this changed of place could affect the plants.
The answers are a, igneous, and b, sedimentary. Hope this helped!
Answer:
Meteorologists use computer programs called weather models to make forecasts. Since we can't collect data from the future, models have to use estimates and assumptions to predict future weather. if there are no meteorologist who would prepare those models
