32.5kg-1 s
31.5kg-1
30.8kg-1 s
30.0kg-1 s
Correct answer is D
Flow = rate = \(\frac{mass}{time}\)
= \(\frac{1000 \times 540}{5 \times 3600}\)
= 30.0kg-1 s
0.4eV
2.5eV
3.0eV
7.0eV
Correct answer is C
Work function = 5 - 2
= 3eV
3V
6V
24V
48V
Correct answer is A
\(\frac{V_s}{V_p}\) = \(\frac{N_s}{N_p}\) = \(\frac{I_p}{I_s}\)
\(\frac{100}{400}\) = \(\frac{V_S}{12}\)
V = 3V
Which of the following is required to convert a milliammeter to an ammeter?
A high resistance in parallel
A high resistance in series
A low resistance in parallel
A low resistance in series
Correct answer is C
No explanation has been provided for this answer.
If the maximum voltage across a 100ohms resistor is 20V, then the maximum power it can dissipate is
5.00W
4.00W
2.00W
25W
Correct answer is B
P = \(\frac{V^2}{R}\)
= \(\frac{20 \times 20}{100}\)
= 4W
