It is easier to turn the steering wheel of a large diameter than that of a small diameter. Give reason.

The sound produced by a large drum is louder than that of a small one.

Assertion : The water rises higher in a capillary tube of small diameter than in the capillary tube of large diameter. Reason : Height through which liquid rise in capillary tube inversely proportional to the diameter of capillary tube.

Lithium is more metallic than beryllium. Give reason.

It is easier to pull a suitcase that has wheels rather than a suitcase without wheels.

Iron tyres are mounted on the wooden wheels of a tonga. Initially the diameter of the iron tyre is:

A galvanometer coil is replaced by another coil of diameter one-fourth of the original diameter and the total number of turns as ten times the original number. What will be the new diflection if the same current is passed through it? Old deflection is theta .

Sound waves from a loudspeaker spread nearly uniformly in all directions if the wavelength of the sound is much larger than the diameter of the loudspeaker. (a) Calculate the frequency for which the wavelength of sound in air is ten times the diameter of the speaker if the diameter is 20 cm. (b) Sound is essentially transmitted in the forward direction if the wavelength is much shorter than the diameter of the speaker. Calculate the frequency at which the wavelength of the sound is one tenth of the diameter of the speaker described above. Take the speed of sound to be 340 m s^-1 .

At Wesley's Pizzeria the small pizza is 4 inches smaller in diameter than the large pizza, whose diameter is 16 inches. If each pizza is cut into eight equal slices, one large slice is approximately what percent larger than one small slice ?

An iron tyre is to be fitted onto a wooden wheel 1.0 m in diameter. The diameter of the tyre is 6 mm smaller than that of wheel the tyre should be heated so that its temperature increases by a minimum of (coefficient of volume expansion of iron is 3.6xx10^-5//^@C )
