A 2.0 mH inductor is connected in parallel with a variable capacitor. The capacitor can be varied from 100 pF to 200 pF. What is the minimum oscillation frequency for this circuit?

The oscillating frequency is from 251613.43 Hz to 388835.1 Hz

Explanation:

L = 2.0 mH = 2 × 10⁻³ H

c = 100 pF to 200 pf

π = 3.142

oscillating frequency

When c = 100 pf (100 × 10⁻¹²) :

oscillating frequency

Substituting values

When c = 100 pf, f = 388835.1 Hz

When c = 200 pf (200 × 10⁻¹²) :

oscillating frequency

Substituting values

When c = 200 pf, f = 251613.43 Hz

The oscillating frequency is from 251613.43 Hz to 388835.1 Hz

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
