Step 1
The mirror equation is given by \(\frac{1}{f} = \frac{1}{v} + \frac{1}{u}\), where \(f\) is the focal length, \(v\) is the image distance, and \(u\) is the object distance. The magnification (\(m\)) formula is \(m = \frac{-v}{u}\). Show moreā¦

Please answer the following question, all parts, thank you. A. When a light bulb is connected to a 12-volt battery, the current of 0.3 A flows through it. When the same light bulb is connected to a 6-V battery, the current through the light bulb will be about: B. You need 64 J of work to push a 4-C charge from point A to point B in an electric field. What is the voltage between these two points? C. A 32-volt battery supplies a light bulb with 144 J of energy each second. Find the current that flows through the light bulb. D. An electric appliance draws 3600 C of charge each minute when connected to a 90-V battery. What current passes through the appliance? E. A parallel plate capacitor with air between its plates has a capacitance of 3 pF. Then, the distance between the plates is decreased 4 times and a dielectric with a dielectric constant of 1.8 is inserted to fill the space between the plates. The new capacitance is about:
