A 100 F capacitor and a 225  resistor are connected in series with a 75.0 V battery. The switch is closed and the capacitor begins to charge.  

a)When does the capacitor hold 15.0 % of its maximum charge? Express your answer in milliseconds.

b)What is the voltage across the resistor at this same time?

Please state your answers as clear as possible and show all the steps and formulas used. Thank you!!!

There are no results for Drugs of Abuse Mr. V, a 47 year-old man, was recently promoted as a director of a transportation company. A routine inspection of the books shows that a large sum of money is missing. Subsequent investigation finds that Mr. V has been spending more than $20,000 a month to buy cocaine; currently he consumes 2-3 g/d. He also drinks several beers each day and 5-8 shots of vodka in the evening. He spends weekend nights in clubs, where he often consumes 2-3 pills of ecstasy. He began using drugs at age 18; during parties he mostly smoked cannabis (5-6 joints per weekend), but also tried cocaine. This “recreational use” came to an abrupt halt when he married at age 27 and entered a professional training program that allowed him to obtain his current job, now jeopardized by his cocaine use. 1. Is Mr. V addicted, dependent, or both? Explain your reasoning. (5points) 2. What is the reason for the use of several different addictive drugs at the same time? (5points) 3. Exogenous cannabinoids (marijuana) include several pharmacologically active substances, but the main psychoactive alkaloid is called __________________________. (2points) 4. When CB1 receptors are activated by marijuana it produces several effects. List at least 3 of the effects. (3points) 5. Ecstasy is a psychoactive drug primarily used for recreational purposes. Ecstasy increases the activity of three brain chemicals. Describe the three brain chemicals that it increases. (5points)

A) Electrons accelerated by a potential difference of 13.16 V pass through a gas of hydrogen atoms at room temperature. Calculate the wavelength of light emitted with the longest possible wavelength.

B) Calculate the wavelength of light emitted with the shortest possible wavelength.

Consider the settlement in U.S. v. Halifax and the Corporate Integrity Agreement entered into by Halifax Hospital Medical Center, which addresses methods for preventing Anti-Kickback violations. What measures required by the Corporate Integrity Agreement do you believe will be most effective in preventing future violations? Which, if any, do you think will be least effective or ineffective in preventing future Anti-kickback violations? Explain your reasoning.

What is the rms current through the resistor? Tries 0/20

What is the average power dissipated in the circuit? Tries 0/20

What is the peak current through the resistor? Tries 0/20

What is the peak voltage across the inductor? Tries 0/20

What is the peak voltage across the capacitor? Tries 0/20

The generator frequency is now changed so that the circuit is in resonance. What is that new (resonance) frequency?
