We have 15 laptops with 15 power supplies. Each laptop needs 240 watts. Each power supply requires 100 watts. How much power do I need total to supply? What is the maximum rating or amperage should my power source to meet safety standards?
My power bill has more than doubled since I had my neutral wire repaired. We had a power surge that took out a bunch of appliances and ever since then our power bill has doubled. I live in a townhouse and my neighbor has more square footage and pays about 45% of what I pay.
*PLEASE READ* In no way is this an attack on the video game industry, Kickstarter, or crowd funding in general and I think David Crane is no doubt a huge inspiration. I’m merely asking whether or not a line should be drawn when funding things that don’t exist. Should there be regulations? Higher expectations? Guarantees from the people getting the money? A person or company can take as much crowd funded money as they want and never have to give anything back in return. Is an idea worth $900000? Again, I’m simply putting this out there to get people thinking. Please leave your comments below and let’s have a civil debate.

one of the cables on my manual boat hoist snapped. I purchased a new one, but am unsure of how to replace the cable. I am not good at things like this. Is it easy? if not what is a reasonable amount to pay someone to do the repair?
A crane lifts a 425 kg steel beam vertically upward a distance of 78 m. How much work does the crane do on the beam if the beam accelerates upward at 1.8 m/s^2? Neglect Frictional forces.
I feel like you can’t add the accelerations, you’d have to subtract because they’re in opposite directions.
If I got in a pinch during a power outage and connected a 12 volt to 110 volt power convertor to the battery of my lawn tractor (via a cigarette lighter connection that I can install), how much power would be available? I have a typical $900 Lowes lawn mower with a 15.5 HP Briggs engine. And I don’t have the power convertor yet, so I can buy any size.
