QV= 1/2(mv^2) Q is the charge V= potential V= speed m= mass Q * 25000= 0.5 * 0.000839* 1170* 1170 Q= 574/ 25000= 0.023 C See if this can help
Let C = Annual income (22/100)* C = Annual Budget= 400* 12 C= 400* 12*100/ 22= 21818 Her annual income is $21818 Good luck Mariya.
C is correct (X1 + X2)^2 + ( y1 + y2)^2 = D^ 2 ( 2 + 4)^2 + (2+6)^2= D^2 36 + 64 = 100= D^2 D= root of 100= 10 D is the distance Ignore the minus sign in the given values
Lifted weight= Bouyant force g*[(He density)*V+650+4600]=Air density *V*g g= gravity= 9.8 N/Kg Air Density= 1.29 Kg/m^3 He Density= 0.179 Kg/ m^3 Ballon Voulme= Gas Volume= Air volume approximately Solving the equation V= 4227 m^3
