State Pascal’s law. Write any one application of law which is stated by you. |
|
Answer» Pascal's law-The external applied to a confined LIQUID is distributed and applies a force by distributed transmitted in all directions and applies a force on the opposite side.Formula of Pascal's law-where,F = force appliedP = pressureA= cross sectional areaApplication of Pascal's law-Hydraulic lift- If we give PRESSURE (P1) to the side of the input force then the force applied is distributed through all the PARTS in the lift and it experiences a large amount of force to the output side (P2). in this the initial difference is same.Hydraulic brakes- It is generally used in brakes of car by a systematic arrangement of braking MECHANISM which uses brake FLUID when we applied a force to the paddle it gets distributed through all the ends of the master brake and then to the brakes. |

An object is thrown vertically upwards and rises to a height of 13.07m. Calculate (i) the velocity with which the object was thrown upwards. (ii) the time taken by the object to reach the highest point. { take s=h(height) and a=g (acceleration due to gravity)} g=9.8m/s2 |
|
Answer» (i) To FIND Initial VELOCITY (u) we Will use, => v = u + GT => 0 = 16 +(- 9.8) t => 0+16 = -9.8t => 16/-9.8 = t => 1.63s = t(ii) To find TIME , we will use => v²- u² = 2gs Now put values, => (0)² - u² = 2*-9.8*13.07 => u² = 256.172 => u = √256.172 => u = 16 |

(a) A body of mass 10 kg is initially moving with a speed of 4.0m s –1. A force of 30 N is now applied on the body for 2 seconds.(i) What is the final speed of the body after 2 seconds?(ii) How much work has been done during this period?(iii) What is the initial kinetic energy?(iv) What is the final kinetic energy?(v) What is the distance covered during this period?(vi) Show that the work done is equal to the change in kinetic energy? |
|
Answer» - Mass of body = m = 10 Kg Initial VELOCITY of body = u = 4 ms-¹ Force ACTING = F = 30 N Time = t = 2 sHere we will find acceleration of the body. F = ma30 = 10aa = 3 ms-²Using first equation of motion we will find the final Velocity of body.i). v = u + at v = 4 + 3 × 2 v = 10 ms-¹Again, USING third equation of motion we will find the distance travelled.Let the distance travelled = Sv² = u² + 2aS(10)² - (4)² = 2 × 3 × S6S = 84S = 14 m ii). For work done,W = FSW = 30 × 14 W = 420 J iii). For initial Kinetic energy,K.E. = 1/2 mu²K.E. = 1/2 × 10 × 4 × 4 K.E. = 80 J iv). For Final Kinetic Energy,K.E.' = 1/2 mv²K.E.' = 1/2 × 10 × 10 × 10K.E.' = 500 J v). As calculated above distance travelled,S = 14 m vi). W = ∆K.E.W = K.E.' - K.E.W = 500 J - 80 JW = 420 J |
