On the other hand, the moon are revolving around the planets. The composition of the star are absolutely different from the planets and there are lots of star but the sun is the closest to the earth.
Answer:

Explanation:
In a single-slit diffraction pattern, the location of the first minimum is given by

where
L is the distance between the slit and the screen
is the wavelength
a is the width of the slit
In this problem, we have
(location of first minimum)
L = 1.068 m (distance of the screen)
(width of the slit)
Solving the equation for
, we find the De Broglie wavelength of the electron:

b. current will stop flowing.
c and d possible for thousands of volts
Explanation:
An optical image formed from the apparent divergence of light rays from a point, as opposed to an image formed from their actual divergence.
