Your parent has discovered that you have accidently left the bathroom light on for a whole 45 minutes!!! It is a 50W bulb as well! They are going mad with you! You have cost them a fortune! You are grounded and will get no pocket money for the whole
month. By using a calculation, show them the actual cost of this terrible mistake and then explain to them why they need "to take a chill pill" and get less stressed. (The cost of electricity in your town is P5.00/kWh)

- The immediate cause of many deaths is ventricular fibrillation, an uncoordinated quivering of the heart, as opposed to proper beating. An electric shock to the chest can cause momentary paralysis of the heart muscle, after which the heart will sometimes start organized beating again. A defibrillator is a device that applies a strong electric shock to the chest over a time of a few milliseconds. The device contains a capacitor of a few microfarads, charged to several thousand volts. Electrodes called paddles, about 8 cm across and coated with conducting paste, are held against the chest on both sides of the heart. Their handles are insulated to prevent injury to the operator, who calls Clear! and pushes a button on one paddle to discharge the capacitor through the patient's chest Assume an energy of 3.00 102 W s is to be delivered from a 30.0-F capacitor. To what potential difference must it be charged?arrow_forwardA student stands on a thick piece of insulating material, places her hand on top of a Van de Graaffgenerator, and then turns on the generator.

In order for the three lights to be bright enough to be seen in daylight, each of the three RL = 50 N lights must dissipate P = the 3 lights are connected in parallel (see the drawing), and the open circuit voltage of the battery (that is, the voltage when there is no current) is Vo = 110 volts. What is the maximum internal battery resistance R; allowable given that each lamp must dissipate 220 watts? 220 watts. Suppose %3D %3D Ri Vo RL pyriarrow_forward
- A student reaches to open a door and gets a small electric shock. She knows that the shock is caused by static electricity, but it seems like in the winter she gets shocked more than in the summer. The student asks her science teacher if there are times of the year when there is more static electricity that builds up than other times of the year. The teacher replies that there is, and it depends on the humidity, or moisture in the air. The more humid the air is, the less static will build up and, therefore, the less you get shocked. Explain why static electricity does not build up as much when the air is humid. In your response, be sure to include: • an explanation of static electricity is formed. • an explanation of why the student felt a shock when reaching for the door handle. an explanation of how moisture in the air allows static electricity to dissipate.arrow_forwardA student reaches to open a door and gets a small electric shock.
