chemistry the branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances.

Science the intellectual and practical activity encompassing the systematic study of the structure and behaviour of the physical and natural world through observation and experiment.

Biological specimens are often examined by microscopy. However, microscopy with visible light is limited to viewing details of a

Alborosie

Answer:

(a) Wavelength = 4.85 x 10^-12 m

(b) Maximum uncertainty = 5.27*10^-25 kgm/s

Explanation:

(a) Calculating the wavelength using the formula;

λ= h/p

but p = mv

Where;

m = mass of electron = 9.1 x 10-31

h = 6.625 x 10^-34

= h/mv

= 6.625 x 10^-34 / (9.1 x 10^-31 x 1.5×10^8)

= 4.85 x 10^-12 m

so, the wavelength is short enough to reveal molecular details at the atomic level.

(b) Find attached of part b
