Answer:
The derived unit of pressure is newton per metre square (Pa). It is a derived unit because it's obtained by adding two or base quantities.
The symbol is Pa and the expression in terms of SI base units is m-¹kgs-²
Answer:
C. Electron beams have much shorter wavelengths than visible light
Explanation:
A beam of electrons is used to illuminate and create magnified images of specimens in an electron microscope. The resolution of a microscope increases with a decrease in the wavelength of the light it uses for illumination. The wavelength of electrons used in the electron microscope is about 100,000 times shorter than that of visible light. Therefore electron microscopes have a resolution thousand times better than the light microscope.
Answer:
It would have to be passive immunity
