$C = 4 \ \mu F = 4 \cdot 10^{-6} \ F. \newline
q = Cu = 4 \cdot 10^{-6} \cdot 2 = 8 \cdot 10^{-6} = 0.000008 \ C.$

Answer:

The total distance is 24 m.

The tiger's resultant displacement is 8 m.

Explanation:

Given that,

Width of tiger= 8 m

Tiger starts from the right side of the cage,

Paces to the left side

$\Delta x_{1}=+8\ m$

Then, back to the right side,

$\Delta x_{2}=-8\ m$

finally, back to the left

$\Delta x_{3}=+8\ m$

We need to calculate the total distance covered

Using formula of distance

$d= x_{1}+x_{2}+x_{3}$

Put the value into the formula

$d=8+8+8$

$d=24\ m$

We need to calculate the tiger's resultant displacement

Using formula of displacement

$D=\Delta x_{1}+\Delta x_{2}+\Delta x_{3}$

Put the value into the formula

$D=8+(-8)+8$

$D=8\ m$

Hence, The total distance is 24 m.

The tiger's resultant displacement is 8 m.

Sergeeva-Olga [200]

The direction is something between west and north. That is, a heading between 270 and 360. The exact direction depends on the airplane's airspeed and the wind speed.

Nesterboy [21]

<span>The physical property that the symbol IencI represents is the net of the current that flows through the Amperian loop. The Amperian loop is not actually present, but instead is the area around a current that would exist assuming that Ampere's law is accurate. It is essentially an invisible loop that surrounds the current and represents the physical property of the current.</span>
