Answer:
So electric field between the plates will be equal to
Explanation:
We have given potential difference between accelerating plates = 24 KV = 24000 volt
Distance between the plates d = 1.5 cm = 0.015 m
We know that potential difference is given by V = Ed, here E is electric field and d is distance between plates
So
E = 1600000 N/C =
So electric field between plates will be equal to
Answer:
Explanation:
The acceleration of the train is given by:
where:
u = 5 m/s is the initial velocity of the train
v = 45 m/s is the final velocity of the train
t = 8 s is the time taken for the train to increase the velocity
Substituting numbers into the formula, we find
Answer:
option E
Explanation:
The correct answer is option E
Writing the relation between wavelength and frequency
f is the frequency
v is the velocity of wave
λ is the wavelength
From the above expression we can clearly see that frequency is inversely proportional to wavelength.
When the distance between the two successive crest is decreased then wave length of the wave also decrease.
If wavelength of the wave decreases then frequency of the wave increase.
hence, we can say that both wavelength and the frequency changes.
