 Question: Calculate the time required to heat 20 kg of water from 100C to 350C using an immersion heater rated 1000 W. Assume that 80% of the power input is used to heat the water. Specific heat capacity of water = 4200 J/Kg - k Ans: Let us consider the required time is t. power of the immersion heater is 1000W, 80% power is used only so used power = 1000*80/100 = 800W.work done by the immersion heater due to this power is W = P*t = 800tthis is the form of electrical energy this energy will be used to heat the water soHeat give by the Heater = Heater taken by the water800t = ms(T2 -T1)800t = 20*4200*[(273+35) - (273+10)] we have added 273 because we will take temp. in kelvin800t = .....Read more...
 Question: Two bodies are connected with a spring and one of the particles is given a velocity v find 1* maximum velocity of second particle and 2* max. extension in the spring. Answer fast please! Ans: when velocity is given to one body the that time the amplitude of oscillations will be maximum compression in the spring . At the time of maximum compression, velocities of both the bodies will be equal say V1. and this velocity be the velocity of the second body at the of release after compression. so by law of conservation of momentum ---m1*v = (m1+m2)V1 if the mass of bodies is m1 and m2so V1 = (m1*v) / (m1+m2) ------------------------------------(i)by the conservation of e .....Read more...
