Answer:
The centripetal acceleration will be "21.785 m/s²".
Explanation:
The given values are:
Time,
t = 0.85 seconds
Length of rope,
r = 0.40 m
Mass of ball,
m = 0.80 kg
As we know,
⇒ 
On substituting the values, we get
⇒ 
⇒ 
⇒ 
The centripetal acceleration will be:
⇒ 
⇒ 
⇒ 
⇒ 
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.
Answer:
Option D
4200 W
Explanation:
Power, P is also given as the product of voltage and current, expressed as P=VI
Here, P is power, V is voltage in the xircuit and I is current theough voltage.
Taking 12 V for voltage across and 350A for current across circuit then power will be
P=350*12=4200 W
Therefore, option D is correct.
