Passage No. 7

Sound is a kind of energy and it needs a medium to travel as it is a kind of longitudinal wave. The speed of sound in different medium is different.Along with the nature of the medium temperature also affects the speed of the sound. At 25ºC speed of sound in some medium is given below :

1. Air – 346 m/.s

2. Water (Distilled) – 1498 m/s

3. Water (Sea) – 1531 m/s

4. Flint Glass – 3980 m/s

5. Steel – 5960 m/s

Sound energy gets reflected through a suitable reflecting surface. An echo is a reflected sound which is heard separately. The sensation of sound persists in our brain for about 0.1sec. To hear the echo clearly at 22ºC, the minimum distance between the source of sound and obstacle should be 17.2 m as the speed of sound in air at that temperature is 344 m/s.

 

Question. The speed of sound is more in sea water than in distilled water at the same temperature because of

(i) taste of sea water is different from distilled water

(ii) density of sea water is more than distilled water

(iii) sea water can conduct electricity

(iv) animals can survive in sea water.

Answer : (ii) 

 

Question. An echo is returned in 3 sec. at 22ºC in a hall. What will be the distance of reflecting surface from the source.

(i) 1032 m
(ii) 516 m

(iii) 258 m
(iv) 344 m

Answer : (ii) 

Question. The speed of sound in space will be

(i) 0 m/s
(ii) 332 m/s

(iii) 596 m/s
(iv) 1498 m/s

Answer : (i) 

Question. In the same medium the speed of sound

(i) increase with temperature

(ii) decreases with temperature

(iii) remains same

(iv) first increase then decrease

 

Answer : (i) 

 

Passage No. 8

In everyday life, we see some objects at rest and others in motion. An object may appear to be moving for one person and stationary for some other. Most motions are complex. Some objects may move in a straight line, others may take a circular path. The simplest type of motion is the motion along a straight line. The shortest distance measured from the initial to the final position of an object is known as the displacement.

If the object covers equal distance in equal intervals of time, it is said to be in uniform motion. During uniform motion of an object along a straight line, the velocity remainse constant with time. In this case, the change in velocity of the object for any time interval is zero. However, in non-uniform motion, velocity varies with time. Non-uniform motion is of two types –

uniform acceleration and non-uniform acceleration. If a car travelling along a straight road increases its speed by unequal amount in equal intervals of time, the car is said to be moving with non-uniform acceleration whereas, if its speed increases or decreases by equal amount in equal interval of time, it is said to be moving with uniform acceleration.

 

The table given below shows distance (in metres) travelled by three cars A, B and C. Read this data carefully and answer the questions that follow :

 

 

Question. Which of the cars is moving with uniform motion?

(i) A
(ii) B

Answer : (ii) 

 

 

Passage No. 9

There are two forms of mechanical energy in an object – kinetic energy and potential energy. Kinetic energy is associated with an object’s motion, while potential energy is the stored energy in an object as a result of its vertical position i.e. height. The total amount of mechanical energy is the sum of these two forms of energy. A group of students are studying the relationship between the Potential Energy(PE), Kinetic Energy (KE) and total mechanical energy (TME) for a cart rolling down and up on the incline plane. The four different locations of the cart in (cm) are given below in fig 1 and energy values of the cart in fig 2. On the basis of these observations answer the following questions.

 

 

Question. At which position, the potential energy is minimum?

(i) 0.50 m
(ii) 1.00 m

(iii) 1.20 m
(iv) 1.45 m

Answer : (i) 

Question. Which conclusion regarding the total mechanical energy (TME) of the cart is right with the data values?

(i) The TME increases as the cart rolls upward decreases as it rulls down.

(ii) The TME decreases as the cart rolls upward and increases as it rolls down.

(iii) The TME decreases as the cart rolls upward and decreases as it rolls down.

(iv) The TME remains constant during the cart’s motion along the incline plane.

Answer : (iv) 

Question. During motion of cart from location C to D :

(i) Both the K.E. and P.E. increases

(ii) Both the K.E. and P.E. decreases

(iii) The K.E. increases and P.E. decreases

(iv) The K.E. decreases and P.E. increases

Answer : (iii)

Question. For which of the following positions along the track does the cart have the smallest K.E.?

(i) 30 cm
(ii) 90 cm

(iii) 50 cm
(iv) 150 cm

 

Answer : (iv)
