A tube open at both ends has length 47 cm. Calculate the fundamental frequency of air column.(Neglect end correction. Speed of sound in air is 3.3 x102 m/s).

Answer»

Given : L = 47 cm = 47 x 10-2 m, v = 3.3 x 102 m/s

To find : Fundamental frequency of air column (n)

Formula: n = \(\frac{v}{2L}\)

Calculation: From formula,

n = \(\frac{3.3\times10^2}{2\times47\times10^{-2}}\)

\(\frac{330}{94}\times10^2\)

= antilog [log(330) – log(94)] x 102

= antilog[2.5185 – 1.9731] x 102 

= antilog[0.5454] x 102 

= 3.512 x 102

∴ n = 351.2 Hz

Ans: The fundamental frequency of air column is 351.2 Hz.

What is relative motion ? Explain it

Answer»

Relative velocity is defined as the velocity of one body with respect to another body. 

Let us consider two observers A and B are making measurements of an event P in space from two frames of reference as shown in figure. At the beginning let the two origins of the two reference frames coincide and are on the same line. 

Let the observer B is moving with a constant velocity VBA with respect to A. Now we can connect the positions of the event P as measured by A with the position of P as measured by B. 

As B is moving with constant velocity at the time of observation of event P, the frame B has moved a distance XBA with respect to A. 

XPA = XPB + XBA → (1) 

"The position of P as measured by observer A is equal to the position of P as measured by B plus the position of B as measured by A". 

eq (1) can also be written as VPA = VPB + VBA → (2)

State Kepler’s laws of planetary motion.

Answer»

Kepler’s first law (Law of orbit): 

Every planet revolves around the sun in an elliptical orbit with the sun situated at one of the focii of the ellipse.

Kepler’s second law (Law of equal areas): 

The radius vector drawn from the sun to any planet sweeps out equal areas in equal intervals of time, i.e., areal velocity of the radius vector is constant.

Kepler’s third law (Law of periods):

The square of the period of revolution of the planet round the sun is directly proportional to the cube of the semi-major axis of the elliptical orbit.

Explain advantages and disadvantages of friction.

Answer»

Advantages of friction : 

1) Safe walking on the floor, motion of vehicles etc., are possible only due to friction. 

2) Nails, screws are driven into walls (or) wooden surfaces due to friction.

3) Friction helps the fingures hold the things (or) objects like pen, pencil and water tumbler etc. 

4) Speed running vehicles etc. can be stopped suddenly when friction is present, otherwise accidents become large. Due to friction vehicles move on the roads without slipping and they can be stopped. 

5) The mechanical power transmission of belt drive is possible due to friction. 

Disadvantages of friction : 

1) Due to friction there is large amount of power loss in machines and engines. 

2) Due to friction wear and tear of the machines increases and reducing their life. 

3) Due to friction some energy gets converted into heat which goes as waste.

What is the general name for the group of enzymes that catalyzes carbohydrates metabolism by hydrolyzing the glycolytic  bond

Answer»

The three key enzymes of glycolysis are hexokinase, phosphofructokinase, and pyruvate kinase. Lactate dehydrogenase catalyzes the transfer of pyruvate to lactate.

31.

What is the type of glycolysis that take place in the absence of oxygen

Answer»

When oxygen is not present or if an organism is not able to undergo aerobic respiration, pyruvate will undergo a process called fermentation. Fermentation does not require oxygen and is therefore anaerobic. Fermentation will replenish NAD+ from the NADH + H+ produced in glycolysis.

32.

Outcomes of Glycolysis. Glycolysis starts with one molecule of glucose and ends with two pyruvate (pyruvic acid) molecules, a total of four ATP molecules, and two molecules of NADH.

A pendulum bob of mass 100g hangs by a thread l=2m.It is pulled aside by 60° and released.Find the tension when bob is at lowest point.

Answer» When Bob is at the lowest point, tension(T) provides the net centripetal force along with Mg:

Mgl(1-cos60°)=(1/2)Mv^2

So v^2=gl

So

T-mgcos60°=mv^2/l

T=1.5N
