Consider a solenoid of length l, n windings, and radius b (l is much longer than b). a current i is flowing through the wire. if the length of the solenoid became twice as long (2l), and all other quantities remained the same, the magnetic field inside the solenoid would: a: become twice as strong. b: remain the same. c: become one half as strong.

50 g of ice at 0°c is dropped in a beaker containing 100 g of water at 0°c. what will be the contents of the beaker after 5 hours? assume that the room temperature is 0°c.

Simple machines can a. increase force only b. decrease force only c. increase or decrease force

The pressure increases by 1.0 x 104 n/m^2 for every meter of depth beneath the surface of the ocean. at what depth does the volume of a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^−2m on an edge at the ocean's surface, decrease by 7.5 x 10−10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^−2, delta v=7.5x10^−10. at some point l needs to be cubed. why p is divided by delta v?
