The part of the electromagnetic spectrum closest to radio waves is <u> microwaves</u>.
The wavelength of radio waves ranges from 10 cm to more than 1 km. The part of the electromagnetic spectrum that occurs closest to the radio waves is called the microwave region.
Microwaves have wavelengths ranging from around 1 mm to 10 cm.
The waves overlap in the region of 10 cm.
Thus, the region of electromagnetic spectrum closest to radiowaves is <u> microwaves.</u>
Answer:
Therefore the capacitance of the capacitor is 2.38 * 10⁻⁵F
Explanation:
We apply the concepts related to Power and energy stored in a capacitor.
By definition we know that power is represented as
Where,
E= Energy
t = time
to find the Energy we have,
With the energy found we can know calculate the Capacitance in a capacitor through the energy for capacitor equation, that is
Therefore the capacitance of the capacitor is 2.38 * 10⁻⁵F
<span>You are given a circuit that contains a 6.0-v battery, a 4.0 ohm resistor, a 0.60 micro farad capacitor, an ammeter, and a switch all in series. You are asked to find the current reading after the switch is closed. Apply ohms law where V = IR where V is the voltage, I is the current and R is the resistor.</span>
V = IR
I = V/R
I = 6 volts / 4 ohms
I = 1.5A
When the switch is closed, the cathode side plate begins to fill up with electrons when it was originally empty before the switch was closed. When it fills up the cathode side of the circuit, the current decreases. And when the capacitor cannot hold more electrons, the current will stop. The higher the capacitance, the higher is the capacity to store electrons.
Answer:
12.6 m/s
Explanation:
We know that the linear speed v = rω where r = radius and ω = angular acceleration. Given that ω = 62.8 rad/s and r = 20 cm from center = 0.2 cm
So, v = rω
= 0.2 m × 62.8 rad/s
= 12.56 m/s
≅12.6 m/s
