Q. If a soldier can carry a load of 40 kg for 5 km, how much weight can he carry for 10 km if the weight carried is directly proportional to the distance? (2020)
A.
20 kg
B.
30 kg
C.
40 kg
D.
50 kg
Solution
If distance doubles, weight carried is halved. So, 40 kg / 2 = 20 kg.
Q. If a solid cylinder rolls without slipping, what fraction of its total kinetic energy is translational?
A.
1/3
B.
1/2
C.
2/3
D.
1
Solution
For a solid cylinder, the total kinetic energy is KE_total = KE_translational + KE_rotational = (1/2)mv^2 + (1/2)(1/2)mR^2(ω^2). Since ω = v/R, the translational part is 2/3 of the total.
Q. If a solid cylinder rolls without slipping, what is the ratio of its translational kinetic energy to its rotational kinetic energy?
A.
1:1
B.
2:1
C.
1:2
D.
3:1
Solution
For a solid cylinder, the translational kinetic energy (KE_trans) is (1/2)mv² and the rotational kinetic energy (KE_rot) is (1/2)(Iω²). The ratio KE_trans:KE_rot is 1:2.
Q. If a solid sphere and a solid cylinder of the same mass and radius are released from rest at the same height, which will have a greater speed at the bottom?
A.
Solid sphere
B.
Solid cylinder
C.
Both have the same speed
D.
Depends on the mass
Solution
Both will have the same speed at the bottom due to conservation of energy, as they start from the same height.
Q. If a solution has a vapor pressure of 80 mmHg and the pure solvent has a vapor pressure of 100 mmHg, what is the mole fraction of the solvent?
A.
0.8
B.
0.75
C.
0.6
D.
0.5
Solution
Using Raoult's Law, the mole fraction of the solvent can be calculated as 80 mmHg / 100 mmHg = 0.8, which corresponds to a mole fraction of 0.75 for the solvent.
