Answer:
I’m pretty positive that it’s 3 seconds
Hope this helps!
First, calculate for the distance between the given points A and B by using the equation,
<span> D = sqrt ((x2 – x1)2 + (y2 – y1)2)</span>
Substitute the known values:
<span> D = sqrt((9 – 2)2 + (25 – 1)2)</span>
<span> D = 25 m</span>
I assume the unknown here is the time it would require for the particle to move from point A to B. This can be answered by dividing the calculated distance by the speed given above.
<span> t = (25 m)/ (50 m/s) = 0.5 s</span>
<span>Thus, it will take 0.5s for the particle to complete the route. </span>
Here I =0.4 amp and t=2hr or 2×60×60 sec
We known I=nQ/t where Q is charge and n is no of charge.
n=It/Q
0.4x(2x60x60)/1.6x10^-19
The answer is 80 J of electrical energy
