What is momentum tell me explain |
Answer» Answer:Momentum is a physics term; it refers to the quantity of motion that an object has. A SPORTS team that is on the move has the momentum. Momentum can be defined as "mass in motion." All OBJECTS have mass; so if an object is MOVING, then it has momentum - it has its mass in motion. ━━━━━━━━━━━━━━━━━━━━━━━ btw GOOD evening MIS and unid karte hai aapka saam rageen hoo aapke sathi ke saath ━━━━━━━━━━━━━━━━━━━━━━━ |

A particle of mass m revoles in a vertical cir ular path of radius r. If is just complete the cycle then find the tention |
|
Answer» Let a small body of mass 'm' attached to a string and revolved in a vertical CIRCLE of radius 'r'. We know that weight of the body always acts vertically downward and tension in the string towards the centre of the circular path.Let v 2 is the speed of the body and T 2 is the tension in the string at the lowest point B. So at the lowest point T 2 = rmrm+mg ..(1) +mg ..(1)TOTAL energy at bottom +mg Total energy at bottom=PE+KE=0+ 21 MV 22= 21 mv 22 ...(2) +mg ..Let v 1 is the speed and T 1 is the tension in the string at highest point A. +mg ..(1)Total energy at bottom=PE+KE=0+ 21 mv 22= 21 mv 22 ...(2)Let v 1 is the speed and T 1 is the tension in the string at highest point A.So, T 1 = rmv 12−mg ....(3)Total energy at A=PE+KE =2mgr+ 21 mmv1
....(4)From equations (1) and (3)T 2 −T 1 = rmv 22+mg−( rmv 12 -mg) = rr (v 22−v12 )+2mg 2 )+2mg ...(5)By law of conservation of energy 2 )+2mg .. 12=4rg ...(6)Putting this value in EQUATION (5)TT −T 1 = rm −T 1 = rm (4rg)+2mg −T 1 = rm (4rg)+2mg =4mg+2mgT -T 1 =6mg Hope this will help you... Sweet dreams buddy... |

In the shown network, charges in capacitors are same. Then C 2 /C 1 is |
|
Answer» Answer: Two different VALUES capacitors are CONNECTED in parallel with each other. When charge Q is given to that combination then the distribution of that charge will depends over the value of each CAPACITOR connected in parallel. ACCORDING to the formula.. Q/V= C.. As the capacitance increases the charge storing capacity is also increases so that case the charge distribution is higher for the higher capacitance and charge distribution is lower for lower capacitance |

An electric heater of resistance 230 ohm is connected to 230 volt supply calculate the heat energy produced by it in one second |
|
Answer» Answer: Given:Resistance of the electric heater = 230 ohms = R • VOLTAGE or the potential difference = 230 volts = V Time = 1 second = t To FIND : Heat energy produced by the heater in 1 second Heat energy = Vxlxt Using ohms law : V=IxR 230=1x230 | = 1 ampere The CURRENT passing through the heater is 1 ampere Now using the formula: Heat = 230x1x1 Heat = 230 Joules The heat energy produced is equal to 230 joules Note:this can also be FOUND with the formula 1²RT #BrainLock. |

an immersion rod of 2kw and 220v rating is used to heat 15 litres of water if initial temperature of water is 20 degree Celsius. what would be the temperature after heating it for 15 minutes. the specific heat capacity of water is 4200j/kg degree Celsius. |
|
Answer» Answer: Explanation: 1 lt = 1dm³ = 1000cm³ 15lt = 15000 cm³ so, MASS of WATER = 15000gm = 15 kg HEAT = mS(T - 20) 2000 × 15 × 60 = 15 × 4200 × (T - 20) 1200/42 = T - 20 28.57 + 20 = T so, T = 48.57° C |

1. What do you understand by area? State its SI unit. |
|
Answer» Explanation: The MOLAR mass of ethanoic acid is 2(12)+2(16)+4(1)=60 g/mol. The mass of ethanoic acid is divided with molar mass of ethanoic acid to obtain number of moles of ethanoic acid. Number of moles of ethanoic acid = 60g/mol 2.5g =0.04167mol The mass of benzene is 75 grams or 1000 75 =0.075 kg. The molality of ethanoic acid in benzene is the ratio of the number of moles of ethanoic acid to the mass of benzene (in kg). It is 0.075kg 0.04167mol =0.556m |
