Answer: Fluorescence microscope
Explanation:
The basic function of a fluorescence microscope is to irradiate the specimen with a desired and specific band of wavelengths. A fluorescence microscope uses a mercury or xenon lamp to produce ultraviolet light. The light comes into the microscope and hits a dichroic mirror. The dichroic mirror reflects the ultraviolet light up to the specimen. The ultraviolet light excites fluorescence within molecules in the specimen. The objective lens collects the fluorescent-wavelength light produced. This fluorescent light passes through the dichroic mirror and a barrier filter, making it to the eyepiece to form the image.
Answer:
A. No precipitate is formed.
Explanation:
Hello,
In this case, considering that both calcium chloride and barium chloride are CaCl₂ and BaCl₂ respectively, due to their high polarity by cause of the ionic bond they have between calcium and chlorine and barium and chlorine we say they are highly soluble in water, therefore, A. No precipitate is formed.
Best regards.
Answer:
Force of repulsion.
By decreasing distance and increasing charge on both objects.
Explanation:
Force of repulsion is present between two negatively charged objects due to their same charge. if both charges are opposite to one another so it exerts force of attraction on one another. If we decrease the distance between two negatively charged objects so they exerts more force of repulsion on one another or by increasing power of charge on both objects also increases force on one another.
