Pure research becomes ___ when scientists develop a hypothesis based on the data and try to solve a specific problem
Inessa05 [86]

Answer:

The answer is <u>applied research</u>

Explanation:

Pure research becomes <u>applied research</u> when scientists develop a hypothesis based on the data and try to solve a specific problem.

This is because the pure research try to understand, predict or explain the behavior of different phenomena <em>(the data)</em> while the applied research try to develop new technologies or methods (<em>hypothesis)</em> to take part, intervene and/or create changes on these phenomena and solve a <em>specific problem.</em>

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
