Readme [11.4K]

Explanation:

Given that,

A person walks 9.0 km directly east and then turns left and heads directly north for 12.0 km.

We need to find his displacement from the starting position.

We know that,

Displacement = shortest path covered

D=\sqrt{9^2+12^2} \\\\D=15\ km

For direction,

\theta=\tan^{-1}(\dfrac{d_y}{d_x})\\\\\theta=\tan^{-1}(\dfrac{12}{9})\\\\= $$53.13^{\circ}

Hence, this is the required solution.

A capacitor is connected to an ac generator. As the generator’s frequency is increased, what happens to the capacitor connected
Bad White [126]

Answer:

Current in the capacitor increases as the frequency of the generator increases

Explanation:

Xc = 1/2πfC = 1/ wC

Since frequency is inversely proportional to reactance of a capacitor,

as the frequency increases, the capacitance decreases and tend towards behaving like a wire with zero resistance as such the generator send high current to the capacitor, the current in the capacitor increases.
