66m
136m
264m
528m
Correct answer is B
2 × Distance = speed × time
2 × Distance = (340) × (0.8)
= 272/2
Distance = 136m
0.33
0.50
1.50
3.00
Correct answer is C
Weight in Air = 45N
Weight in Water = 15N
R.D = \(\frac{45}{45-15}\) = 1.50
3,600J
6,000J
7,200J
14,400J
Correct answer is C
Power drawn by the resistor = IV = (2)(3) = 24W = 24J/s
Energy dissipated = power × time = (24)(5)(60) = 7200J
1.10Ω
1.64Ω
2.44Ω
27.50Ω
Correct answer is C
\(\frac{R_1}{R_2}\) = \(\frac{L_1}{(100 − L_1)}\)
\(\frac{R_1}{2}\) = \(\frac{55}{45}\)
R\(_1\) = 2 × \(\frac{55}{45}\)
= 2.44Ω
10cm
20cm
30cm
40cm
Correct answer is D
F= 15cm
M = 3
M = \(\frac{v}{u}\)
V =3u
\(\frac{1}{f}\) = \(\frac{1}{u}\) + \(\frac{1}{v}\)
\(\frac{1}{15}\) = \(\frac{1}{u}\) - \(\frac{1}{3u}\)
\(\frac{1}{15}\) = \(\frac{2}{3u}\)
U =10cm
D = u + v
= 10 +30 = 40cm
