Answer:
(a) 
(b) 
(c) 
Explanation:
Given that,
(a) An electron accelerated from rest through a potential difference of 100 V. The De Broglie wavelength in terms of potential difference is given by :
Where
m and e are the mass of and charge on an electron
On solving,
V = 100 V
(b) V = 1 kV = 1000 V
(c) If 
Hence, this is the required solution.
We add the values on each of the riders:
300 + 20 + 8
= 328 grams
Answer:
The magnitude of the vertical component of its velocity as it hits the ground is 30 m/s. The horizontal distance from the firing point is 750 meters.
It obeys law because the physics of quantum space are so slow and small it’s actually really fast
The phase of matter has a large impact upon the elastic properties of a medium. In general, the bond strength between particles is strongest in solid materials and is weakest in the gaseous state. As a result, sound waves travel faster in solids than in liquids, and faster in liquids than in gasses.
