A particle of charge +18.5C and mass 4.84 × 10-5 kg is released from rest in a region where there is a constant electric field of +578 N/C. What is the displacement of the particle after a time of 1.89 × 10-2 s? 1) F=Eq 2) a=F/m 3) d=vt+1/2at^2 1) F= 10693 N 2) a=...

The object increases by 505%

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.

**pre-alg**

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
