Answer:
The focal length of the lens is 5.54 cm and the height of the image is -0.89 cm.
Explanation:
Given that,
Height of object h = 2 cm
Object distance u= -18 cm
Image distance v= 8 cm
We need to calculate the focal length of the lens
Using formula of lens
Where, f = focal length
Put the value into the formula
(II). We need to calculate the height of the image
Using formula of magnification
Put the value into the formula
Hence, The focal length of the lens is 5.54 cm and the height of the image is -0.89 cm.
Answer:
See the explanation below
Explanation:
Many of the advantages are due to higher power generation efficiency compared to other forms of power generation.
For example, a smaller amount of uranium compared to carbon or oil is needed to produce the same amount of energy.
Nuclear power plants can be installed in isolated and safe places far from the cities and not necessarily near a river, as if it happens in hydroelectric plants.
A nuclear power plant can supply power to large metropolises, ensuring a level of reliability of 98%, compared to thermoelectric and hydroelectric power plants.
Its working fuel is uranium or plutonium, energy that is used to heat bars that are immersed in water generating steam. The amount used of radioactive material (uranium or plutonium) is very small compared to fossil fuels such as coal and oil.
