Два куска железной проволоки имеют одинаковые массы. Длина одного из них в 10 раз больше длины другого. Какой кусок проволоки имеет большее сопротивление; во сколько раз?
в 10 раз больше у длинного куска....так как формула R=p*l/s

How to Write a Vacation Postcard
In the era of the Internet, many people have lost touch with the basic art of letter writing. Sometimes we travel to locations that don't have the Internet connection and an e-mail is no longer an option. The digital revolution has left a few gaps and a basic postcard writing is one of them.
These simple steps given below refresh your memory on how to send a hand-written note to your family and friends when on vacation.
The style of your writing is usually going to be very informal. People often use incomplete sentences that still make sense just so they can fit more into the available space. This style has been adapted today and used when sending text messages. Paragraphs, too, tend to be disregarded in order to conserve more space.
Step 1. Write the day's date in the top right-hand corner of the left section of the postcard.
Step 2. Write the address of your current location in the top right-hand corner of the left section of the postcard. The address should consist of the town and state or town and country, unless, of course, you are expecting a reply back from your postcard.
Step 3. Write the greeting under the date. A simple greeting like "Dear Joe" is sufficient.
Step 4. Compose the body of the postcard. Traditionally, this section includes information about your journey, the weather, and the places you've visited, etc.
Step 5. Sign the postcard below the body on the right hand side of the leftsection of the postcard.
Step 6. Place name and mailing address of the person you are writing to in the centre of the right-hand section of the postcard. Remember to include your full name, zip code and country, especially when writing from overseas.
Step 7. Stick a stamp on the top right hand corner of the right section of the postcard and mail. Check local rates to ensure your postcard arrives.
