Difination of dimensionnal formula and eqution |
|
Answer» ensional formula is defined as the expression of the PHYSICAL quantity in terms of its basic unit with proper dimensions. For example, dimensional force is. F = [M L T-2] It's because the unit of Force is N or kg*m/s2.An equation obtained by equating a physical quantity with its dimensional formula is CALLED the dimensional equation of the physical quantity.the dimensional formula of an quantity is expressed in terms of SEVEN fundamental physical quantities.the seven fundamental physical quantities are mass kg e time second length metre TEMPERATURE Kelvin CURRENT ampere luminous intensity candela amount of substance mole.any physical quantity other than these seven are called derived quantities. |

a stone is released from the top of the tower to the surface of the earth calculate its final velocity just before touching the ground |
|
Answer» u = Initial velocity of the stone = 0 m/s v = FINAL velocity of the stone s = Height of the stone = 19.6 m G = Acceleration DUE to GRAVITY = 9.8 ms−2 ∴ v 2 − 02 = 2 × 9.8 × 19.6 ⇒ v 2 = 2 × 9.8 × 19.6 = (19.6)2 ⇒ v = 19.6 ms−1 Read more on Sarthaks.com - https://www.sarthaks.com/9589/stone-released-from-tower-height-calculate-its-final-velocity-just-before-touching-ground |

For echo to take place for least distance, the distance between the source of sound and the reflecting surface should be (Take: sound speed = 340 m/s.persistence time 1/10 s)(A) 17 cm(8) 17m(C) 1.7 m(D) 34 m |
|
Answer» to the REFLECTING surface and back should be at least (344 m/s) × 0.1 s = 34.4 m. Thus, for hearing distinct ECHOES, the MINIMUM distance of the obstacle from the source of sound must be half of this distance, that is, 17.2 m. |

the distance travelled by an object in time hundred plus minus one years is 5.2 plus minus 0.1 M what is the speed and its error |
|
Answer» 19.23 ± 0.56 m/s.Explanation:From the QUESTION we GET that distance = 100 ± 1 seconds and the time = 5.2 ± 0.1 m.So, we know that Speed = Distance/Time. HENCE, the Speed = 100/5.2Speed = 19.23 m/s. Since, for every value there is an error in the data, hence we let that Δx be the error in speed.So, we get that Δx/x= Δa/a + Δb/b im which a is the distance and b is the time.Δx/x=0.1/5.2 + 1/100Δx/x= 0.019 + 0.01So, on calculating Δx/x=0.029Hence, Δx = 19.23 × 0.029Therefore, Δx = 0.56Consequently the Speed will be FOUND to be = 19.23 ± 0.56 m/s. |
