3. Explain the relationship between power, energy and time.
likoan [24]
There is a very simple relationship between the three. First off, power is the amount of energy used over a certain amount of time. Energy is the capacity of carrying out that power. Lastly, time depends on how much energy you have to exert the work.

Hope this helps :)

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
