Answer:
Explanation:
Let the distance traveled in first half is d and then in the next half is also d.
Let the time taken in first half is t1 and the time taken in the second half is t2.
Total time taken
The average speed of a body is defined as the total distance traveled by teh body to the total time taken.
It will take a total of 15 minutes i believe. t = d/r
t = 5mi/20mph = .25hr
60 min = 1 hr
.25*60 min = 15 minutes it wil take him
Explanation:
Given that,
Initial speed of the electron,
Distance, s = 5 cm = 0.05 cm
Acceleration of the electron,
(a) Let v is the electron's velocity when it emerges from this region. It can be calculated as :
v = 871779.788 m/s
or
(b) Let t is the time for which the electron take to cross the region. It can be calculated as:
Hence, this is the required solution.
