Calculate the magnitude of the magnetic field at a point 123 cm from a long, thin conductor carrying a current of 1.47 A. The permeability of free space is 1.25664 × 10−6 T · m/A.
Answer in units of T

Two small loudspeakers are connected to a single source—an 798 Hz sine-wave generator—so that they are coherent. Suppose that initially the speakers are side by side, a few centimeters apart, equidist
Or is it gateway to another area in our own universe?-possibly. We cannot know the answer to this question. If there were such things and we could manage those things to our advantage, then it would b
Universe started with a size of a Plank size, inflation lasted 10^-35 second, and inflated the universe by a factor of 10^50 in that time frame.-Sure, a Planck nugget of low entropy would be v = 4/3 p
Please help me UNDERSTAND this! Im lost and I tried reading the book, but it doesnt explain it well. Thanks a lot!
A spherical balloon has a radius of 7.00 m and is filled with helium (density=.179 kg
Let me explain.
Say the Universe is a soda can and gravity is a magnet (perhaps invisible magnet). Is the magnet somewhere inside the can, or perhaps the magnet is outside of the can in which would e
A snow skier weighing 400 N has an initial speed of 10 m/s at the bottom of a hill which is fast enough to just coast to the top and stop. How high is the hill? The answer is 5 m but how do you get th
Like pure water is H2O, so why does it liquefy at such a different temperature compared with pure liquid Hydrogen or Liquid Oxygen, the elements its made of?-Why are liquid Hydrogen and liquid Oxygen
Ive to explain about it, and I know the laws are important, but why is it important, in general? :D-Do you want to drive a car that has an engine?
Do you want to understand how to build a better fire?
In the figure, a block slides along a track from one level to a higher level after passing through an intermediate valley. The track is frictionless until the block reaches the higher level. There a f
A 10 gram ball is thrown horizontally at a wall with speed 15 m/s and bounces back with the same speed. The magnitude of the impulse on the ball is? The answer is 0.3 N s but how do you come up with t
a block of mass m=.5kg is sliding on a horizontal table with coefficients of static and kinetic friction of .8 and .5 respectively. It is attached to a wall with a spring of unstretched length l=.13m
