X is the anode and very high current is used
X is the anode and Y is the cathode
Y is the cathode and X is the anode
Y is the anode and very high current is used
Correct answer is D
Metals and hydrogen are deposited at the cathode, while non-metals and oxygen are deposited on the anode
∴ metals Y will form the anode which is deposited at the cathode made of x
8.58 x 10-19 J
8.50 x 10-15 J
8.58 x 10-17 J
8.85 x 10-18
Correct answer is A
Work function, w = hfo 6.6 x 10-34 x 1.3 x 1015
= 8.58 x 10-19

A radioactive isotope has a decay constant of 10-5s4. Calculate half life
6.93 x 10-5s
6.93 x 105s
6.93 x104s
6.93 x 10-4s
Correct answer is C
T (1)/2 = (0.693)/λ = (0.693)/10-5
= 0.693 x 105
= 6.93 x 104 sec
