Answer:
Renewable energy is a type of energy that can be renewed easily, such as sunlight. By using Solar panels to collect the suns energy, we are not depleting it, so this source is renewable.
Non-renewable energy is something that cannot easily be replenished. An example would be oil because oil takes millions of years to form and cannot be renewed easily.
Answer:
0.541 nm
Explanation:
The condition for maxima is,

Here, m=0,1,2,.....
And d is the slit separation, m is the order of maxima,
is the wavelength.
Given that, the 17.3 eV electron posses a wavelength of

And the order of maxima is
.
And the angle at which first order maxima occur is,
.
Put these values in maxima condition while solving for d.

Therefore, the slit separation is 0.541 nm.
