0.63A
0.50A
0.31A
0.22A
Correct answer is A
I = \(\frac{f}{n} = \frac{1}{6 - 2}\)
I = \(\frac{v}{R + r} = \frac{2}{3} + \frac{1}{6} = 0.63\)A
possesses low internal resistance
can be recharges
has shorter life span
possesses high e.m.f
Correct answer is D
No explanation has been provided for this answer.
6.0 x 10-5C
1.2 x 10-4C
2.4 x 10-4C
4.8 x 10-4C
Correct answer is C
C = \(C_1 + C_2 = 2 + 2 = 4 \mu F\)
but Q = CV
= 4 x 10\(^{-6}\) x 120
= 4.8 x 10\(^{-4}\)
\(\therefore\) Each of the capacitor has a charge of \(\frac{4.8 \times 10^{-4}}{2}\)
= 2.4 x 10\(^{-4}\) C
When depreciation is deducted from Gross National Product, the result is
Total national income
Gross domestic product
Net national product
Net domestic produc
Correct answer is C
Net national product is the total value of goods produced and services provided in a country during one year, after depreciation of capital goods has been deducted.
When two like charges are brought together, the potential energy of the system formed will
increase because work is done against the field
increase because work is done by the field
decrease because work is done by the field
decrease because work is done against the field
Correct answer is A
if two like charges are close together, they repel each other. moving them closer together requires working against repulsive force which increases the potential energy of the system.
