A 220 pF capacitor is charged through a 1200 ohm resistor.

 Find the charge when the capacitor when t = 500 nanoseconds. Assume charging starts at t = 0

I already found the time constant to be 264 nanoseconds

Is there a general rule? I want to cut out an 8 inch by 8 inch piece. So I need the diameter/ circumference to stay the same for at least 30 ft. I was thinking about using white birch or pine.

Can I pay someone to install electricity in a log home that was built before electricity became common? Or would I need to take apart the old log home

I saw a documentary explaining what happens when everyone tries to pull their money from the banks at once only to find that it isn't there. So obviously the people who had precious metals or other valuable resources did well because they could trade it for stuff but did people who hid their live savings in their mattress do well because they are one of the few people who had enough money to get by?

 I am trying to relax my muscles, especially my torso and back. I had a hard life with mental issues and I have been incredibly tense for over a decade. Now that I got medical help I am starting to relax but when I tried to, it really hurt. Like my body was fighting the relaxation. This hurt more than my intense exercises. Anyone had something similar happen and if I can do anything about it besides pain pills. 

I am working on my mental health and I come to realize that I feel that I have to keep working and do more. I hate this and I don't like working but can bare it. I honestly feel like even if I was the first man on Mars, I would still feel like I should have done more. How do I get rid of this feeling because I hate it. I want to be able to only work 40 hours a week and not feel guilty about not working overtime every day even when I do not need the money or have the slightest clue what I would even want to spend it on. I can't work overtime forever because of other health issues, it would drive me to an early grave. Almost had.

I went to a fishing pond the other day and I can't seem to catch anything. I waited till the Bober was under water and yanked it but I never catch anything. I use night crawlers and the lures with 3 hooks.

We are restoring a vintage camper. A 1959 15ft kenskill camper. A guy we took to have it looked at said we should get electric brakes. Do we even need brakes because I would imagine these old campers didn't have electric brakes and would stop when the car stopped. Also it would seem I would have to get a mount and an electric brakes controller to install in the car and I don't want to do that. Could I wire it to my existing tail light wires so it will brake when both of the tail lights get power?

I'm over two weeks into my weight loss program and Today my upper abdominal area hurts. I can tell it's close to the skin and I haven't been doing abdominal workouts lately. It feels like it's being squeezed.

I heard that doing stuff like biceps curls to gain muscle mass makes your arms feel lighter, more relaxed, and makes lifting every day objects easier. Is this true?

I am restoring a 1959 Kenskill camper with my mother. I looked under it and the axle is pretty rusty but will it still work? it is not bent. It is a 4 inch drop axle. also the 4 leaf springs seem ok. they are rusty but not damaged. the weird thing is when I measured the center of the eyes, I get 27 1/2" on one side and 27 3/4" on the other. there is a metal plate that connects it to the frame but it is not perpendicular. can these springs stretch because I can not find a 27 1/2" long 4 leaf double eye spring

I want to buy a new backpack and don't know what I should get. I want something that will last for decades. Will canvas last this long or should I get real leather. From what I read it seems real leather has some issues like if it gets wet that i would need to dry it immediately and routinely apply oil. Is this an issue?

I am a college student and got a part time job restoring boats. It's alot of manual labor. After I work I am sore and on my days off I feel lethargic. Will this go away after a few weeks after my body adapts to it?

Long story short I lost something off a dock and I know exactly where it is but I have to wait till it is warm enough to dive down and get it. Is there a rule of thumb I can use to tell the water temperature like for example if the air temperature is 70 degrees the water is x degrees colder.

Which is a stronger, longer lasting material? I want to buy a leather backpack as I am tired of my cloth backpacks falling apart after a few years. Ideally it would last long enough to be a family heirloom. Money is not much of an issue.

I saw a video about these Japanese researchers who made a container to grow a chicken without the need of the shell. This got me wondering if I could use this method to clone mammals? For example, the pangolin population is being overhunted and I think the best way to save them is to make them a pet. The axolotl species was saved from extinction by becoming a popular pet. The problem is pangolins usually only produce one offspring a year, so if I can take their cells, make it an embryonic cell, and grow it in this shell less egg technique, it may save them.

I want to make a pathway where I can walk on moss barefoot comfortably. Should I place the moss spores directly over soil or should I place small rocks over the soil than the moss. If I do the small rocks will it be uncomfortable to walk on or will it have a massaging effect

I am curious to what will happen if most of China gets sick from the corona virus. Will silver and gold be in much higher demand?

I heard about a story where a president during the 1700s or 1800s said it was constitutional for a private citizen to own a war ship or something. Do you know who the president was and what exactly the man had?
