Answer:
Wavelength,
Explanation:
It is given that,
Velocity of an electron,
Mass of an electron,
We need to find the wavelength of an electron. It can be calculated using the De- Broglie wavelength as :
So, the wavelength of an electron is . Hence, this is the required solution.
Answer:
Distance covered is: 45 meters
Displacement is 15 meters to the right of where he started
Explanation:
Notice that Brady has walk a path that looks like an incomplete rectangle of height 5 meters and length 25meters, although he actually didn't cover the full length (25 meters) when getting back to the point where he started (he made just 10 meters instead of 25 after the third turn right) See attached image.
Therefore, Brady's displacement is 15 meters to the right of where he started, and the total distance he covered is :
Distance = 5m + 25m + 5m + 10m = 45m
