Answer:
Explanation:
First we need to find the capacitance of the capacitor.
The capacitance is given by:
Where 
is the air permittivity, which is approximately 8.85 * 10^(-12)
The radius is 12/2 = 6 mm = 0.006 m, so the area of the capacitor is:
So the capacitance is:
The time constant of a rc-circuit is given by:
So we have that:
Answer:
Earth's gravity would increase with the increase in Earth's mass. The driver hits a bump and the gravell falls out, so that the mass of the truck is one half as large after hitting the bump.
Explanation:
hope this helps :)❤️
As you approach the police car with blaring siren, you hear a change in pitch and frequency. The apparent pitch changes as a result of the Doppler effect. Frequency determines pitch; frequency and wavelength are inversely proportional. You wouldn't "hear" either one. The result is pitch.
D) pitch and frequency.
B the answer is b in this equation
