Answer:
Z = 138.5 Ω
Explanation:
In a series RLC circuit the impedance is
Z =
the capacitive impedance is
X_C = 1 / wC
the inductive impedance is
X_L = wL
in this exercise indicate that C = 50 10⁻³ F, L = 0.3 H and the frequency is f=60 Hz
angular velocity and frequency are related
w = 2π f
w = 2π 60
w = 376.99 rad / s
let's calculate
Z =
Z =
Z = √19179.6
Z = 138.5 Ω
Answer:
The net force is the vector sum of all the forces that act upon an object. That is to say, the net force is the sum of all the forces, taking into account the fact that a force is a vector and two forces of equal magnitude and opposite direction will cancel each other out.The magnitude of the net force acting on an object is equal to the mass of the object multiplied by the acceleration of the object as shown in the formula below. If the net force acting on an object is zero, then the object is not accelerating and is in a state that we call equilibrium.Jan 4, 2016

Answer:
B. ceramics
Explanation:
Ceramics are materials which are inorganic and non-metallic materials made from compounds of metals and non metals. They are usually oxides, carbides and nitrides. They are stronger, harder and more resistant to heat than a wide variety of other types of materials. They found a great use in the industry such as for making glass wares, pottery , valves, spark plugs, pressure sensors, vibration sensors,bricks, cement,insulators, resistors, superconductors, capacitors ,ceramic rotors e.t.c.
Answer:
gets higher
Explanation:
There are videos that show the range of human hearing. If you would play the video, you would notice that if the frequency increases, the pitch would also increase.
