The string of a guitar is vibrating at a frequency of 200 hertz. Calculate its timeperiod? |
|
Answer» Explanation:ANSWER f= 2L 1 μ T where f is frequency, T is Tension, L = length and μ is constant ∴f∝ L T ⇒ f 1 f 2 =( T 1 T 2 )( L 2 L 1 ) SQUARING on both sides and REARRANGING we GET ⇒ T 1 T 2 = (f 1 L 1 ) 2 (f 2 L 2 ) 2 L 2 =2L 1 ,f 1 =200HZ,f 2 =300Hz Substituting above values we get T 1 T 2 = 1 9 |

Antonio has70 kg of cement and240 kg of sand and you want to prepare equal bags with the same proportion of cement and sand to store in the storage room, but you want to buy the minimum number of bags possible. How many bags should he buy? |
|
Answer» ber of bags has to be a divisor of 70 already 240 and it has to be maximum. Therefore, your gcd. We decompose the numbers: 70 = two ⋅ 5 ⋅ 7 240 = two 4 ⋅ 3 ⋅ 5 The common bases are two Y 5 and its minor exponents are 1 Y 1 . Therefore, m C d ( 70 , 240 ) = two 1 ⋅ 5 1 = 10 MUST buy 10 sacks. Each bag will have 7 KG of cement and 24 of sand. |

Are these quantities ‘Rest’ and ‘Motion’ absolute? Justify your answer with an example. |
|
Answer» Rest and motion are the RELATIVE terms because they depend on the observer's FRAME of reference.If an observer is at rest in his or her own frame of reference , but he MAY be MOVING in other observer's frame of reference. So if two different observers are not at rest with respect to each other, then they too GET different results when they observe the motion or rest of a body. |
