15 s
6 s
12 s
9 s
2.

increases by 5 times
increases by 10 times
remains same
increases by 7 times
3.
When a cycle tyre suddenly bursts, the air inside the tyre expands. This process is
isothermal
adiabatic
isobaric
isochoric
4.
The load – elongation graph of three wires of the same material are shown in figure. Which of the following wire is the thickest?
wire 1
wire 2
wire 3
all of them have same thickness
5.
A planet moving along an elliptical orbit is closest to the Sun at distance r1 and farthest away at a distance of r2. If v1 and v2 are linear speeds at these points respectively. Then the ratio \({v_1\over v_2}\) is
\({r_2\over r_1}\)
\(({r_2\over r_1})^2\)
\({r_1\over r_2}\)
\(({r_1\over r_2})^2\)
6.
A particle is moving with a constant velocity along a line parallel to positive X-axis. The magnitude of its angular momentum with respect to the origin is
zero
increasing with x
decreasing with x
remaining constant
7.
A body of mass 1 kg is thrown upwards with a velocity 20 ms-1. It momentarily comes to rest after attaining a height of 18 m. How much energy is lost due to air friction?(Take g = 10 ms-2)
20 J
30 J
40 J
10 J
8.
A vehicle is moving along the positive x direction, if sudden brake is applied, then
frictional force acting on the vehicle is along negative x direction
frictional force acting on the vehicle is along positive x direction
no frictional force acts on the vehicle
frictional force acts in downward direction
9.
Which one of the following physical quantities cannot be represented by a scalar?
Mass
length
momentum
magnitude of acceleration
10.
If the length and time period of an oscillating pendulum have errors of 1% and 3% respectively then the error in measurement of acceleration due to gravity is
4%
5%
6%
7%
1.
Time period is the time taken by particle is return to B = 4 x 3 = 12s
2.
\(v_{m s}=1.73 \sqrt{\frac{k T}{m}}\)
\(\text { AT Increased by } 10 \text { times }\)
\(v_{\mathrm{ms}} \propto \Delta T\)
\(\text { RMS speed increases by } 10 \text { times. }\)
3.
(b)
adiabatic
4.
For the wire 1
Young's modulus is less
\(\text { Young's modulus } Y \propto \frac{F}{A}\)
\(\therefore \text { Area is more }\)
\(\therefore \text { Wire } 1 \text { is thickest }\)
5.
(a)
\({r_2\over r_1}\)
6.
(d)
remaining constant
7.
Mass = 1kg
Velocity v = 20m/s
Height h = 18 m
\(g=10 \mathrm{~m} / \mathrm{s}^{2}\)
\(\text { Potential energy } P . E=m g h\)
\(=1 \times 10 \times 18 =180 \mathrm{~J} \)
\(\text { Kinetic energy } K . E=\frac{1}{2} m v^{2}\)
\(K . E=\frac{1}{2} \times 1(20)^{2}\)
\(=\frac{1}{2} \times 20 \times 20=200 J\)
\(\text { Loss of energy due to air friction }= K.E - P.E\)
\(=200-180=20 \mathrm{~J}\)
8.
(a)
frictional force acting on the vehicle is along negative x direction
9.
Mass, length are scalars. Acceleration is a vector but magnitude of acceleration is a scalar
10.
\(T =2 \pi \sqrt{\frac{l}{g}} \)
\(g =4 \pi^{2} l / T^{2} \)
\(\frac{d g}{g} =\frac{d l}{l}-\frac{2 d T}{T} \)
\(\frac{d g}{g} \% =\left(\frac{d l}{l}\right) \%-2\left(\frac{d T}{T}\right) \% \)
\(=1 \%-2 \times(-3 \%) \)
\(=1+6=7 \% \)
