Answer:
Electron microscope
Explanation:
Electron microscope uses a beam of electrons as energy source. Since the beam has an exceptionally short wavelength, it strikes most objects in its path and increases the resolution of the microscope significantly. Thus it has a higher magnification and resolution.
<span>Of SiF4 and SiBr4, the atom SiF4 is more polar. This is because the cation of both molecules are Silicon, but the anions of each are different. In SiF4, the anion is Fluorine, which is more electronegative than the Bromine in SiBr4, which creates a larger dipole, which results in a more polar molecule.</span>
Answer:
(V-Vo)/t = (30-0)/4 = 7.5 m/s^2.
The correct answer is True , my reason being is because they eat decomposed / decomposing things to get their food, they are not fighters , rather lazy
