TeflonBlixx: This is wrong. The question is to find mass. Not mass conc. Then you used the H conc instead of OH concentration as it is NaOH. I got 0.0202g though. Don't know if I'm correct |

A heating coil of resistance 30ohm is connected to a 240volt supply for 300seconds to boil a quantity of water in a vessel of heat capacity 200j/k. If the initial temperature of the water is 20degree celsius and its specific heat capacity is 4200j/kg/k. Calculate the mass of water in the vessel. (answer=1.67kg. Please solve until you get this answer) 2. A transformer is required to supply 0.2ampere at 100volt from the secondary using a primary voltage of 250volt. if the primary has 120turns, calculate the number of secondary turns and the primary current assuming the transformer is 100% efficient.(answer= 480turns, 0.8ampere. pls solve and get this answer) cc indomixx eben331 drbestjc aceed |

BiafranDel:R=300 ohms, V=240v, t=300s, initial temperature T1=20^oC, final temperature T2=100^oC (since it is at boiling point), heat capacity of vessel C=200J/K, specific heat capacity of water c=4200J/kg/K, mass of water in the vessel m=? >>> Note that both the water and vessel have the same initial and final temperature >>> Heat gained by water + heat gained by vessel = Heat lost by coil >>> mc(T2-T1) + C(T2-T1) = V^2t/R >>> m*4200(100-20) + 200(100-20) = (240^2*300)/30 >>> m*4200*80 + 200*80 = 57600*10 >>> m*336000 + 16000 = 576000 >>> m*336000 = 576000-16000 >>> m*336000 = 560000 >>> m=560000/336000 >>> m=1.667kg >>> m=1.67kg (approx) |

Gracy3535:1 circle = 2pie = teta...where teta=angular displacement. >>> 1/4 of circle = 1/4*2pie = pie/2 >>> therefore teta = pie/2 >>> angular displacement = pie/2...distance s = teta*radius >>> distance s = pie/2*r = pie*r/2. |

TeflonBlixx:Since what we were given was heat capacity of the vessel and not the specific heat capacity of the vessel, so the mass of the vessel is not needed...from the formula of heat capacity: H=C(T2-T1) >>> C=H/(T2-T1). |

A Physics student standing on the edge of a cliff throws a stone vertically downward with an initial speed of 10m/s. The instant before the stone hits the ground below, it is travelling at a speed of 30m/s. If the physics student were to throw the rock horizontally outward from the cliff instead, with the same initial speed of 10m/s, what is the magnitude of the stone just before it hits the ground? (a) 10m/s (b) 20m/s (c) 30m/s (d) 40m/s. PLS SHOW UR WORKINGS!! |
