Two resistors of resistance 19 ohm each are connected in series.
In series combination, equivalent resistance = 19+19 = 38 ohm
Potential difference = 10 V
V/I = R
I ( current ) = V/R = 10 V / 38 ohm = 0.26 ampere
Answer:
v(t) = 21.3t
v(t) = 5.3t
Explanation:
When no sliding friction and no air resistance occurs:
where;
Taking m = 3 ; the differential equation is:
By Integration;
since v(0) = 0 ; Then C = 0
v(t) = 21.3t
ii)
When there is sliding friction but no air resistance ;
Taking m =3 ; the differential equation is;
By integration; we have ;
v(t) = 5.3t
iii)
To find the differential equation for the velocity (t) of the box at time (t) with sliding friction and air resistance :
The differential equation is :
=
=
By integration
Since; V(0) = 0 ; Then C = -48
Answer:
1 thermal to nuclear to mechanical to electrical. 2 thermal to mechanical to nuclear to electrical. 3 nuclear to mechanical to electrical to thermal. 4 nuclear to thermal to mechanical to electrical.
The answer to the question is
<span>PE = W = 1/2 (kx^2)
16.2 = </span>1/2 (k(0.30)^2)
k = 360 J/m^2
