Answer: k = 1163.72 N/m²
Explanation: if the bow obeys hook's law, then force is proportional to extension.
F = ke.
F= Force = 263 N
k = force constant
e = extension = 0.226m
263 = k * 0.226
k = 263/ 0.226
k = 1163.72 N/m²
Explanation:
It is given that the number of electrons passing through the cross-sectional area in 1 s is
. Also, we know that charge on an electron is
, then negative charge crossing to the left per second is as follows.
I- =
I- = 0.544 A
As it is given that the number of protons crossing per second is
, as the charge on the proton is
, then positive charge crossing to the right per second is calculated as follows.
I+ =
I+ = 0.224 A
I = l I+ l + l I- l
So, I = 0.544 + 0.224
= 0.768 A
Thus, we can conclude that the current in given hydrogen discharge tube is 0.768 A.
