                                               Trees 🌲🌳🌴                                                           Trees reduce the urban heat island effect through evaporative cooling and reducing the amount of sunlight that reaches parking lots and buildings. This is especially true in areas with large impervious surfaces, such as parking lots of stores and industrial complexes.                       Keep Nature free from Pollution                           1. keep the environment clean 2. Reduce the usage of your electrical appliances. 3. Drive your car less. 4. Reduce the usage of your wooden stove. 5. Maintain a healthy eco system. 6. Reduce usage of chemicals and pesticides. 7. Recycle the waste products. 8. Reduce carbon footprints. 9. Grow your food locally.llution

  Lemon water is simply the juice of lemons mixed with water. The amount of lemon juice in lemon water depends on the person’s preference. People may drink it cold or hot. Some people also choose to add lemon rind,  mint leaf ,  honey ,  turmeric , or other ingredients. Lemon water has become a popular morning beverage, with people using it as a refreshing pick-me-up due to claims that it can boost energy levels and  metabolism             Lemon juice🍹 benefits           1)  Aids in digestion          2)  Helps you stay hydrated          3) Weight-loss friendly          4)  Prevents oxidation          5)  Supplies a healthy dose of vitamin C          6)  Provides a potassium boost          7)  Helps prevent kidney stones                 How to make lemon juice            1.  Squeeze lemon juice into a glass.           2.   Add warm water.            3.   Stir and enjoy

We have to find  V1 and V2 it by applying nodel analysis at two nodes  ?    Step 1: first nodel analysis         ( (V1-20) /5)  +(V1/10) +((V1-V2) /10) =0            (2V1-40+V1+V1-V2) /10 =0             4V1-V2=40.....................(I)          Now,                 Step 2:  second nodel analysis       ((V2-V1) /10) + (V2/20) -4=0  (2V2-2V1+V2-80)/20=0  3V2 -2V1=80 ......................... (II)               Now equate equation (I) and(II)  to get  the value of V1  and  V2             ( -2V1+3V2=80) *1             ( 4V1- V2  =40) *3              ..............................                -2V1 +3V2 =80                12 V1 -3V2=120              .......................................                 10V1      =200                 V1    =20 V                and put the value of V1 in equation (I) to get the value of V2                      So, V2 =40 V  

Electrical Tutorial 1)   Calculate the equivalent resistance (Req)?          Ans :  first R10 and R8 are in series             So,  R10 =2 ohm                     R8  = 10 ohm               R10+ R8 =(10 + 2 ) ohm = 12 ohm Now,  12 ohm and R9 are in parallel              R9=6 ohm So, Rparallel= (12*6) /(12+6) =4 ohm Now,  R7 and 4 ohm are in series                R7=8 ohm    Rseries =(4+8) ohm =12 ohm R6 and 12 ohm are in parallel                 R6=6 ohm Rparallel = (6*12)/(6+12) =4 ohm R5 and 4 ohm are in series            R5= 4 ohm  Rseries=(4+4) =8 ohm R4 and 8 ohm are in parallel            R4=8 ohm Rparallel = (8*8) /(8+8) =4 ohm R3 and 4 ohm are in series        R3= 4 ohm Rseries=(4+4) ohm=8 ohm R2 and 8 ohm are in parallel           R2 =8 ohm Rparallel= (8*8) /(8+8) =4 ohm   Now R1 and 4 ohm are in series              R1 =6 ohm Req=Rseries=(6+4) ohm=10 ohm
