An AC voltage is applied to a purely capacitive circuit. Just as the applied voltage is crossing the zero axis going negative, w
Fiesta28 [93]

Answer:

The Ic will be zero.

Explanation:

Capacitors have a working principal as follows:

  • As the current flows through the circuit, they store the electrical energy according to certain attributes they have such as the area of the plates and the material's capacitence in between the plates.

An AC voltage increases and decreases between certain maximum and minimum points periodically. So while the AC voltage is on the positive side, the capacitor charges up and when the AC voltage crosses to the negative side, the capacitor takes over and it's current starts increasing as the current coming from the AC source decreases.

So in this case, as the AC voltage crosses zero, the capacitor current was decreasing because the AC voltage was on the positive side and it was charging. The capacitor current will be zero as well and it will start to increase when AC voltage is on the negative.

I hope this answer helps.

How do you use vectors daily without realizing it was a vector?<br><br> I need help ASAP !!!
jonny [76]

Explanation:

Vectors are quantities that has both magnitude and direction. A vector is described in terms of quantity and the direction it is headed.

There are different forms of vectors that are used in our daily life.

  • When we describe the motion of a car and the direction it is heading, we are simply talking about its velocity which is a vector.
  • When we say James treks 2km from his school to the house everyday, we are simply describing his displacement.
  • When we apply a force to push the table from one corner of the room to another point, is simply a vector
  • When we change position, it is a vector application.

Uma massa de 500 Kg desloca-se com velocidade 58 km por hora. Calcule o módulo de sua quantidade por movimento
Simora [160]

The momentum of the object is 8050 kg m/s

Explanation:

The momentum of an object is defined as

p=mv

where

p is the momentum

m is the mass

v is the velocity of the object

For the object in this problem, we have

m = 500 kg is its mass

v = 58 km/h is its velocity

Converting the velocity into m/s,

v=58 \frac{km}{h}\cdot \frac{1000 m/km}{3600 s/h}=16.1 m/s

Therefore now we can find the momentum of the object:

p=(500)(16.1)=8050 kg m/s
