Abattery is used to charge a parallel combination of two identical capacitors. if the potential difference across the battery terminals is v and total charge q flows through the battery during the charging process then the charge on the positive plate of each capacitor and the potential difference across each capacitor are

The brightest star in the night sky in the northern hemisphere is sirius. its distance from earth is estimated to be 8.7 light years. a light year is the distance light travels in one year. light travels at a speed of 3.00 × 108 m/s. calculate the distance from earth to sirius in miles. (1 mi = 5280 ft) g
