0.01 %
7.
A closed cylindrical container is partially filled with water. As the container rotates in a horizontal plane about a perpendicular bisector, its moment of inertia
increases
decreases
remains constant
depends on direction of rotation
8.
Two blocks of masses m and 2m are placed on a smooth horizontal surface as shown. In the first case only a force F1 is applied from the left. Later only a force F2 is applied from the right. If the force acting at the interface of the two blocks in the two cases is same, then F1 :F2 is
1:1
1:2
2:1
1:3

1.
(a)
(B), (C) and (A)
2.
The area under the graph will give total member of gas molecules in the system
\(\mathrm{n} =\frac{P V}{R T} \quad \mathrm{R}=k \)
\(\therefore \quad \mathrm{n} =\frac{P V}{k T} \)
3.
(b)
P, T, U
4.
\(\Delta l \text { verses } \mathrm{E}\)
\(\text { Strain } \propto \text { Stress }\)
Hooke's law is followed
5.
(b)
6.
\(\text { Kinetic energy } E_{k}=\frac{p^{2}}{2 m}\)
\(\frac{\Delta E_{k}}{E_{k}}=\frac{2 \Delta p}{p}\)
\(\text {Given that } \frac{\Delta p}{p}=0.1\)
∴ Increase in kinetic energy
\(\frac{\Delta E_{k}}{E_{k}}=2 \frac{\Delta p}{p} \)
\(\frac{\Delta E_{k}}{E_{k}}=2 \times 0.1=0.2 \% \)
7.
(a)
increases
8.
(c)
2:1
9.
For a free falling body, initial vertical downward velocity = 0
For a body thrown horizontally with a velocity, initial vertical downward velocity = 0
Since both having same initial vertical downward velocity they cover equal vertical distance at any instant
10.

\(\text { Dimension of torque }\)
\(=\left[\mathrm{MLT}^{-2}\right][\mathrm{L}]=\left[\mathrm{ML}^{2} \mathrm{~T}^{-2}\right]\)
\(\text { Energy }=\text { Force } \times \text { displacement }\)
\(\text { Dimension of Energy }\)
\(=\left[\mathrm{MLT}^{-2}\right][\mathrm{L}]=\left[\mathrm{ML}^{2} \mathrm{~T}^{-2}\right]\)
