It makes it harder for the defense to cover you.
Answer:
C) 
volts
Explanation:
f = frequency of oscillator = 1 kHz = 1000 Hz
= 12 Volts
L = Inductance of Inductor = 5 mH = 0.005 H
= Inductive reactance
Inductive reactance is given as
= 
= 
= Capacitive reactance
Capacitive reactance is given as
Impedance of the circuit is given as
Rms Current flowing is given as
A
Rms potential difference across the resistor is given as
volts
Answer:
Part A the answer is the dielectric constant.
Part B Mica- mylar- paper- quartz
Explanation:
The capacity of a capacitor is given by
C = ε ε₀ A / d
Where the dielectric constant (ε) is the value of the material between the plates of the capacitor, we see that as if value increases the capacity also increases.
Another magnitude that we must take into account that the maximum working voltage, the greater the safer is the capacitor
the flexibility of the material must also be taken into account
Part A the answer is the dielectric constant.
Pate B order the materials from best to worst
Mica. The best ever
Mylar Flexible
Paper Low capacity, low working voltage, flexible
Quartz high dielectric, but brittle
Answer:
Zero
Explanation:
According to Newton's second law, the net force acting on an object is equal to the product between the object's mass and its acceleration:
F = ma
For the hockey puck, there are no forces acting on it during its motion, since ice friction and air resistance are negligible. This means that the net force is zero:
F = 0
But this means that the acceleration is also zero:
a = 0
So the hockey puck is moving already at constant velocity. Therefore, there is no need for additional forces.
