A car Moves with a speed of 80/km hr For 15 min and then with a speed of 60/km for next 15 min The total distance covered by the car is? |
|
Answer» Total distance covered = 35 kmExplanation:velocity in first half v₁ = 80 km/HR = m/s= 200/9 m/svelocity in second half v₂ = m/s = 60 X 5/18 = 50/ 3 m/stime = t₁ = t₂ = 15 min = 15 x 60 secDistance covered in first half s₁ = v₁t₁ = =20,000 m = 20 kmDistance covered in second half s₂ = v₂t₂ = = 15,000 m = 15 kmTotal distance covered s = s₁ + s₂ = 20 + 15 = 35 kmAlternate Method :Formula used : If a body covers first half time (t) with velo v₁ and second half time with velo v₂ thenAverage velo = (v₁ + v₂)/2∴ Avg velo v = = 70 km/hrTotal time t = 30 min = 30/60 hr = 0.5 hrTotal dist covered s = vt = 70 x 0.5 = 35 km |

17. A stone of mass 0.25 kg tied to the end of a string is whirled round in a circle of radius 1.5 m with a speed of 40 rev./min in a horizontal plane. What is the tension in the string? What is the maximum speed with which the stone can be whirled around if the string can withstand a maximum tension of 200 N? |
|
Answer» tion:Mass of the stone, m = 0. 25 kgRadius of the circle R = 1. 5 mNumber of REVOLUTION per second n = 40/60 = 2/3 rps Angular velocity The centripetal force for the stone is provided by the tension T in the string That's Maximum tension in the string t max = 200NTherefore the maximum speed of the stone is 34. 64 m/s. ✍ Hope its helpful to you! ✍ |

Complete the analogy : [1] 1 kg x 1 m/s2 : 1 N :: 1 g x 1 cm/s2 : _________ |
|
Answer» Explanation:1 N FORCE is the force which when applied on a 1 kg MASS results to an acceleration of 1 m/s^2 in the BODY. 1 dyne force is the force which when applied on a 1 gram mass LEADS to an acceleration of 1 cm/s^2 in it. 1 kg = 1000 gram and 1 m = 100 cm=> 1 N = 1(kg)(m/s^2)= (1000 gram)(100cm/s^2)= 10^5 dyne. |

What does a pmic do? |
|
Answer» There are PMIC devices which are preset with the relative timing and relationship among the various rails, with some flexibility. Other are more fully user programmable, often via an I2C or PMBus interface, to allow the user to set the specifics of the sequencing and other parameters that the PMIC is managing. In some CASES, a few external cents such as RESISTORS or capacitors may be NEEDED by the PMIC. In very complicated SYSTEMS, a dedicated microcontroller may be used with the SOLE task of providing PMIC functions.Hope it helps you. |
