Answer:

θ = 51.21°

Explanation:

Vh= 193.6 km/h

Va= 141.7 km/hr

Relative velocity ,Vr= 193.6 - 141.7 = 51.9 km/hr

Time taken to cover 71.3 m

h=\dfrac{1}{2}gt^2

71.3=\dfrac{1}{2}\times 9.81\times t^2

t= 3.81 s

t= 0.00105 hr

So the horizontal distance x

x= Vr .t

x= 51.9 x 0.00105  km

x=0.0549 m

x= 54.96 m

Lets take angle is θ

tan θ = h/x

tan θ = 71.3/54.96

θ = 51.21°

A capacitor is connected to an AC generator. As the generator's frequency is increased, what happens to the current in the capac
Licemer1 [7]

Answer:

The current increases.

Explanation:

A capacitor can be defined as an electronic component used in electrical circuits to store charge temporarily.

A capacitor is connected to an AC generator. As the generator's frequency is increased, the current in the capacitor increases as well.

This ultimately implies that, when a capacitor is connected to an AC generator, the frequency of the circuit is directly proportional to the amount of current flowing through it.
